Atkinson dither github (free)

I have linked before (March 14, 2013) to this github as a way to achieve atkinson dithered images for possible use in knitting. I received a post with questions on how to achieve this successfully. I work on a Mac, latest OS. The resulting dithered files were not read when downloaded by any app other than Preview, and resizing within program was poor quality. Here is my work-around: it is always best to resize any of the images to be processed in color or grey scale, before indexing modes or dithering. Once that is achieved, import image into github without changing output size in the program itself, and download. Your own image size will be retained. Now time for another freebie intervention: XnConvert will accept the file, convert it to BMP or other readable formats if preferred, resulting in a knittable image.

Fair Isle single bed 1: float control

Fair isle is the name given to a pattern knitted with 2 colors in each row.  The motifs are easily identified by looking at the holes in the punchcard, or squares on mylar, pixels in programs. While I will be referring to punch card knitting, the same principles apply. Your knit swatch will look like the card, but the design will be squashed, and these designs are generally knit at least one whole tension number looser than when using the same yarns for stocking stitch.  The length of floats created in knitting these fabrics is sometimes an issue, and following are some of the methods that help with “float control”.

Altering the pattern: random holes may be punched in addition to those in the motif and shorten the very long floats, providing this does not distort the pattern too much. Iris Bishop is a designer with an extensive library of such designs.

Hooking up floats: this method works best when the 2 colors used are similar. If they are strongly contrasting there is a possibility of show through where the float is knitted on the same needle as a contrasting stitch. Use the single transfer tool to hook up the float into a needle hook above while leaving the  needle in the position to which it has been selected. If it is a very long float, it may require “hooking up” several times. Show through can be reduced on machines that preselect the needles, if you can place the float on a needle about to knit in the same color as the float (the needle will be selected to upper working position).

Binding with fine yarn: using a fine yarn, even sewing thread, matching the main color of the design, break off a length for every place that will bind the float down, trying to keep unanchored floats to no more than 5 stitches if possible. Make a slip knot at one end, take it under the first float, and place it onto the needle above, leaving the  needle in the position to which it has been selected . Knit the next row, and lay the fine yarn into the needle hook, fastening down the next float by carrying each length horizontally up your fabric and hooking it over your needles as required. Add more pieces of yarn or change colors as needed.

While this method illustrates managing edges of single motif, it also illustrates managing additional threads.

When knitting only a small area in fair isle (single motif), the contrast yarn will pull away from the edge of the patterning. This may result in holes or ladders to either side of the design. The illustration above and the one below from the Brother 940 manual illustrate securing the edges with spare lengths of the main color yarn. The lines of the yarn are in black and pink respectively for the purposes of illustration. Program the machine for single motif, attach each length of spare yarn to a needle adjacent to those pre selected for single motif, in upper working position. Knit one row in pattern to opposite side. Take the extra yarn length between the knitting and the carriage and place it on the adjacent needle in B position (in background color), knit one row to opposite side, repeat wrapping on carriage side throughout the shape.

Latching: Using the latch tool, pick up a short float below the first long float. Slip it behind the latch, catch the next long float in the hook, and pull it through the first. Continue in this way, latching up all the long floats, and then place the last float pulled through into the hook of the closest needle above that is knit in the same color latched up. As the next row is knit, the float will be caught. The disadvantage to this method is that the hooked floats will pull across the fabric, making it pucker. This technique may be done off the machine as well, with the last float sewn in by hand.

Sewing: sew floats in by hand after completion of knitting by catch stitching the longer floats in on the reverse of the knit. As an alternative a sewing machine and “stitch in the ditch” with matching thread while placing the knitting on the machine and carefully stitching down the valleys between the rows of stitches at desired vertical spacing.

Knit linings: these may be in the form of hems or pieces of knit fabric that you attach as you knit, which could be in finer yarn, large stitches, and not necessarily on every needle. Color matching once again matters.

Bonding with fusibles: suitable for yarns that can take hot, damp ironing. It also stiffens the fabric. Some bonding materials are knit, with stretch in one way and not the other, woven ones have no stretch.

Fringing: long floats may be cut and made into fringes. In this instance, the punchcard may be intentionally masked to cover holes and create intended long floats, which may be later cut. The purl side will now become the “public one”.

Mock weaving: use the reverse side of the fabric for a knit woven effect, one example. The pattern on the knit side may become distorted in a way that could be considered an added design feature.

Decorative floats: use the long floats and twist them, or bind, pick up, tuck behind stitches to make decorative fabrics highlighting the purl side.

Ruching in pattern: hooking up stitches as in hems to enclose part or all of the long floats. For this technique, if a lot of ruching is to occur, it may be best to elongate the original pattern to at least X2.

“Stitching in the ditch”: after the piece is finished floats may be anchored by using a straight, medium-sized stitch on the sewing machine. Use thread that matches the main color as much as possible. Place knitting on the machine knit side up. Stitch carefully and slowly in the valleys between rows of knitting in areas with longer spaces between ground and contrast. The same method is sometimes used at standard intervals to secure FI floats when using yarn such as chenille to help avoid “worming” (yarn slipping out in loops) along motif edges as time passes.

Fringing: deliberately planning long floats with the intent of cutting them to create fringed effects. The purl side of the fabric would be used as the “right” side. Specific areas of punchcards could be masked with tape to create wide float areas amid smaller designs, and electronic machine users can control the placement of pixels. Both can vary the designs by exchanging yarn positions in the sinker plate feeder and/or adding additional color striping.

Please note: try any of these techniques on swatches first. There may be changes in the surface of the knit on the knit side such as puckering or bleed through that may require changes. If combining techniques in a garment, each should be tested. If combining FI and “plain knit” one possible solution is to knit the latter in a simple FI pattern using the same color in both feeders, keeping similar texture and weight in both areas. If using several color changes, the card may be marked to help track them.  If self-drawn, repeats lining up in width and height should be knit tested as well.

Combining patterned stripes in stocking stitch: the latter will be single density and different weight than FI. In FI two yarns knit simultaneously, producing a double-thickness fabric. Test on swatches whether doubling the yarn for single color rows works for you. Another option is to knit “plain” bands in a 1X1 fair isle pattern, using the same color yarn in both feeders.

Converted images,”representational knitting”

One bit camera “snaps pictures in digital retro style. I began this tale with a partial shot of my face. The app apparently is no longer available via US App Store (11/15/2017)

resized, greyscale, knittable size bmp

The old bag of tricks did not produce an image I was happy with, I finally used Ggraphicconverter Picture_Mode_ Bitmap for my downloadable file

Migrated from Mac to a PC laptop, opened in WinCrea, the image repeat was downloaded to Passap, program tech 179. The bottom  of the swatch is knit single bed LX (slip stitch), the top is double bed, back bed set N/N, same tension throughout, the middle stripes are operator error in forgetting to make the lock change to LX on the front bed; the gauge is significantly and obviously different

Moving on to a birds’eye backing, the bottom starts the pattern with dark color, top with light (another operator error and a reminder to keep notes even for what may seem obvious); the black is slightly thinner than blue resulting in a change in gauge once again

The bouncing gauges certainly indicate some of the problems in maintaining aspect ratios in representational knits. The best solution may be to do a large swatch in the planned technique that is at least 100 sts X 100 rs in chosen yarn and then adjusting image aspect ratio before knitting the final piece, which in turn may be better done before conversion to final BMP and require repeating the process from its beginning.

For separations such as technique 179, and those by default in Japanese machines for 2 color DB, images must have an even number of rows in length. My original image crop was 73W by 85L pixels, so I had to shorten it by one row, which was actually achievable within WinCrea. The single bed FI swatch measured 7 inches in width, the double bed ones 12 inches at their widest point.

Last but not least, here is my friend Rocco processed via Hyperdither, Mac to PC, to WinCrea, to Passap and knit 150X150 pixels/ stitches

May 24, 2019 a greyscale mode scaled image processed in ditherlicious online produced a sharper, far more defined image than my previous effort 142X146 pixels

I have used this image before, when I posted previously on some ways to reduce colored images to B/W for possible knitting using a Mac computer, please see post on 013/03/14/ color-reduction- conversions-mac-os/. Gimp offers some alternatives to the familiar dithers and is available, free, for both PC and Mac platforms. Tutorial links on Gimp edge detection available online as of May 2019 are listed at bottom of the post.

Threshold adjustments may not be made in indexed images to alter the above image, so it’s back to greyscale. Reductions to greyscale may be achieved through Image_ Mode_ Greyscale or choosing Colors_Desaturate_OK options. Desaturation offers additional choices

Different dithering methods can be specified to counteract quantization-induced banding.
Presets are common features for many Colors commands.
Red levels, Green levels, Blue levels, and Alpha levels sliders set the number of levels for the respective red, green blue, and alpha channels.
Dithering method: can specify the dithering method to use
None: no dithering will be performed
Floyd Steinberg: the most commonly used method of dithering, and the default for this filter
Bayer: the algorithm is characterized by noticeable cross-hatch patterns in the result
Random, random covariant: use randomization of the pixel values to reduce the number of colors
Arithmetic variants are based on magic numbers and arithmetic
Blue noise variants are sometimes thought to be the least distracting

Looking for ways to reduce the noise in dithered images I tried this conversion in XnSketch, using the photocopy effect,  beginning with the colored image of Rocco, the results: imported the result into Gimp and saved it in indexed  2 color BW and in turn, 3 color indexed mode, no color adjustments, finding the result pleasantly simple beginning with the greyscale generated image followed by Mode changes in Gimp, indexed 2 color BW, then indexed 3 color, there appear to be very subtle differences with a bit more detail: Another online resource with an extensive array of dithering options https://app.dithermark.com. Here are 2 conversions using the app, the images are 2 color B/W. The presence of a third color is an illusion created by the difference in the distribution of BW color pixels, they loaded fine as viewed for knitting in Ayab, and in img2track, once I remembered to change its setting to 2 color knitting from the last used one at 4 colors It is possible to reduce images to 4 or 3 colors using the program as well: a slider for color count is used to choose the final number of colors in the reduction. Again, these instances have no added manipulation A series of dithers:
To retain the quality and size of the dithered image, download it, rather than using a screen grab. The software used to separate the chosen dither may alter the result somewhat. I am writing my posts using an iMac M1 with OS 12.0.1. At this point Ayab is not operable, img2track does open images, but in this case, with interesting distortions, and it does not download any files at all. Yet another dithering tool, allows one to draw in dithering mode using a variety of patterns and will dither images. In the latter instance, there is no real opportunity to tweak or alter the result shapes drawn using a few of the large variety of offered patterns:

In this instance, a portrait of a dog wearing a sweater image was generated in Midjourney and scaled to 191X195 pixels.
Dithering online apps were used to reduce the colors in instants to 4, 3, and 2.
The greyscale image was also color reduced and dithered in Gimp.
All results were not adjusted further in any way.
Color reductions could be tweaked a bit further prior to actual knitting.
Magnifying the chosen individual result will help visualize the change in resolution quality of the image in the final knit piece.

Double jacquard separations 4_ making them “work”

Working back to the repeat from post # 3 on this subject, I returned to the drawing board and edited the separations.  Tetris is a tile-matching puzzle video game originally designed and programmed by Alexey Pajitnov in the Soviet Union. The objective of the game is to manipulate tiles, by moving each one sideways and rotating it by 90 degree units, with the aim of creating a horizontal line of ten blocks without gaps. The principle at use for the separated “squares” shapes is to achieve the same result for each of color separation groups (highlighted by dark borders in the charts), by moving them up and down, or changing their positions in the color sequence. The first method (beginning with only one row of ground color) has eluded me in terms of an “error free” result. More than one version consistently in a missing single stitch of color. The latest method shows the problem color “tiles” marked in dark ovals. The column on left is the original separation, A shows the juggled colors, B the pixels, squares, or punched holes for the repeat, and the far column on the right shows markings that may be used to track the color change sequences, which may be transferred to punchcard, mylar, or for any cues in change of sequence your program can provide. The swatch approaches the original intended design far more than any of the previous attempts. It is expected that the background color will be the majority or main color of the design; it gets separated out as first color. By splitting the knitting of most of the needles to the beginning and the end of the sequence (japanese 2 color default) this way, one supposedly eliminates the chance that the needles knitting the second row of each color will knit over, blocking a space yet to be knit in the first row of the design by a color that has not yet been knit. In this small pattern no colors knit more than 3 consecutive stitches at any one time. With some motifs the final alternative is to redesign the motif.

Using the alternative method for decreased elongation of motif upon knitting, here are the working charts for beginning with 2 rows of color 1

GIMP software 2

This is the method I used to achieve the “color separations” in the previous post:

File new: create in canvas size for a knit repeat: deleting the default 0 gives a working surface that is 64X40/ OK for small motifs

Change magnification to 1,000, hit return

GIMP Windows_Dockable items_ navigation will provide an easy slider to adjust sizing as needed

View: show grid, snap to grid

RGB mode

Draw test motif repeat, using the one-pixel pencil tool in B to draw, W to erase

The program allows for combining all items in one window, I prefer not to

test motif

Save the file in native format .xcf  for backup and future changes

Use color markings to outline repeat

Adjust magnification with navigation slider if needed for easier editing

With crop tool, crop area within colored markings; menu_image_crop to selection

Use filter, map tile to view repeat in multiples- adding a 0 to both x and y pixel number values is an easy way to achieve that. The tiled image is in turn easily gridded if such a graph is required- simply go to view, highlight show grid, grab the resulting image, and save

If the repeat is satisfactory: back to image cropped screen, click within the window, go to file export menu, choose the file format, and save as png, BMP, etc for download, or simply screen grab the image in an easy to see size if punching a card or requiring a single repeat chart. I do not own Dak; GIMP does have a .pat read and save, but I have no way of testing whether files are in any way compatible between the 2 programs.

Most electronics are able to take the motif repeat and separate it automatically for a 2 color DBJ knit. If a separation for 2 colors DBJ is required for use with a punchcard, or for any of the fabrics already discussed one needs to return to the .xcf magnified document.

For the simplest DBJ separation, each row will break down into 2 colors, which in turn need to be knit with 2 passes for each color. This method is the one that is most likely to increase the lengthening of the knit image, but one that “always” works.

To lengthen the repeat X2, cropped repeat area needs to be converted to 2 colors or  go to image, mode, click on convert

Gimp 2.8.22: Image, mode, select Indexed 

Open Image Scale window; use image scale tool, clicking once again on selected repeat areaGIMP 2.8.22: highlight number you wish to keep constant

To break the aspect ratio and control one of the 2 values, click on the chain like symbol on right, it will appear “broken”

change the second value

Click on scale image. If the intent is to continue editing by using the pencil tool, the image mode needs to be returned to RGB before proceeding with editing.

Adjust numbers to the desired scaling, height doubled for the original repeat would be 18 pixels in length, here is the result

To separate the rows revert to RGB mode, unselect repeat area by clicking outside its parameters.

row 1/color 1 in DBJ needs to knit in the largest number of “squares”, so my color inversion will begin on design row 2, for color 2; because these are individual pixels, numbering is not possible; I use color guides for the row that need to be inverted and repeat outline, and use the navigation bar to enlarge for easy selection individual rows with the crop tool

After selecting the desired row with the rectangle select tool go to colors_invert, seen here for the first row of color 2, repeat for the length of motif. The result is suitable for use with double length KM built-in features and using the color changer. The black squares represent programmed pixels in download, or what is drawn on mylar/ punched in the card.

If the double length of the separation is required: image _mode _indexed removes red and yellow squares, repeat process described above: select motif, use scale tool over the same area, scale image to 8X36. The caveat here is that one needs to be in the original canvas area: with a beginning canvas that was 64 X40, there is enough room for doubling length once more. Undo scale, use scale tool again, dragging upper and lower corners, keeping an eye on changing numbers in the window for scale tool, type correction to numbers if needed, click on scale,  autocrop to selection for export in the desired format or screen grab and print to the desired size

working with more colors, toward similar goals

adding colors: 3 colors per row motif, drawn in RGB mode

to make it the required triple length

resulting image when scaled to triple pixel height

the still manual color separation: whiting out unwanted colors in each row

double the length again

colored squares represent pixels in download, square in mylar, punched holes in the card

GIMP software 1

GIMP (GNU Image Manipulation Program) is an image retouching and editing program released as free and open-source software. There now is a Mac OS Mountain Lion compatible version. The downloads may be found here, and more links for features, supported file formats, help tutorials. One limitation is that for “color separations” to work by inverting colors one needs to reduce images to 1 bit B/W images, a definite advantage is the speed relative to working in spreadsheet programs. Another drawback is that one is using single-pixel designing, so adding numbers for rows and stitches in a particular format is not possible. My June 10th post on illusion knits illustrated an example in creating repeats for them, here are sample results/charts

Illusion /shadow knitting DIY designs_HK

I have played with excel (and Numbers) before to create charts for various fabrics requiring color separations. My latest efforts relating to this knit group have gone in a different direction; I have also attempted to simplify the technique in terms of following the instructions for knitting them. This sample began with the use of Intwined to create the document and graphs. The first chart is set up with alternate row color striping, color 1=dark, color 2 = light. Blank-colored squares are used as knit symbols, and horizontal dash for the symbol for purl stitches. Beginning on light-colored, even-numbered rows, the design is marked in purl stitches. On odd-numbered rows beginning with row 1, mark all empty squares in the even-numbered light-colored row immediately above it with purl symbols. All unmarked stitches throughout the design are knit, whether, on the “wrong/right” sides, all dashes are purled, patterning occurs on the second row of each color. To visualize the full pattern one may use the add row below feature to expand the graph (the chart below is missing the very first row). Now add the second row of each color and grounding stripe (s) at bottom of the repeat. Most patterns will start the illusion immediately after casting on with dark color, row 1 above. I was interested in my sample having a border of sorts on its top and bottom. The resulting knit swatch shadow sideIntwinded had the capacity for building row by row written instructions for patterns, but there were discrepancies on some rows for these charts, and I opted not to include them.
Note: the program quickly became buggy, unsupported, and unusable on the Mac during the remainder of 2013.

Another program I have just acquired and begun to use is GIMP; it is free, and now also available for use in Mac OS Mountain Lion. Both Gimp and Photoshop make it possible to design using single-pixel pencil and grids to build motifs from scratch as well as gridding of preexisting images. I have a different method for these fabrics using GIMP, which is easier for more complex, overall shapes. The same series of steps may be used for mosaic knitting (the color inversion sequence is different). Below are images generated for a different illusion pattern, I will share my “how-to” for designing the motifs later, referencing mosaics and mazes. To achieve such motifs one is drawing in magnification of multiple hundreds and more, there is no way to number within a one-pixel space, so these charts as generated are lacking numbers for stitches and rows, one drawback. Another is that this color inversion works only in black and white. One advantage: the proper repeat may be cropped and saved with the grid removed in various formats that may be used to import to various machine knitting download programs, and gridded may be used to establish punchcards or mylar repeats.  Screengrabs of magnified charts were saved, and are shown below. Black squares represent purl stitches in the second row of each color. The first row of each color is always knit, not represented in these charts
The red squares are guidelines for no color inversion rows, the yellow ones isolate the repeat the actual repeat color inversion begins on row 1 and follows every other row (if numbered these would be odd rows)  testing the repeat through filter/ map/ tile a working chart that can be printed to suit with dark/light row markings and blank squares for tracking knitting rows in the execution of the pattern A larger version with stitch and row counts marked. The chart represents half the rows in the actual knit. The cast on row counts as knit row 1, color 1, and following the chart beginning with row 2 knit the black squares and purl the white squares. *Change color, knit one row (odd#), on the next row follow the chart, knitting the black squares and purling the white (even#).** Repeat from * to **. the knit swatch: “shadow side” its reverse side for online tutorials, patterns, and inspiration see Woolly Thoughts

Feb 18, 2017, I have recently become curious about creating illusions such as these in crochet, am developing ideas, and returned to this chart. The image below is intended to have symbols and notes superimposed on it. It shows the tiling in a different way, so I thought I would add it to this post as well. Repeats are highlighted with darker borders. The repeat on the right needs to be trimmed if the goal is to achieve matching edges. Row counts on the right would differ in knitting, the plan is to execute this pattern in Tunisian crochet, which handles rows in a very different manner than knitting or standard crochet.

Not all parts are created equal: sinker plates

A recent forum discussion brought up the possibility of exchanging sinker plates between models. This is often possible, with some adjustments at times being required. The images below show the one sinker plate I know of with truly distinct parts, made for the 892E, 894, 4.5 mm Brother punchcard models that had a thread lace capability like that seen in the bulky 260 machines.

the illustrations on operation and parts from the manual

The bottom view in the first photo shows the distinct brushes and their white plastic “arms” (for lack of the technical name). The red line on the right shows the span and “nub” that may not align properly on the knit carriage if there is a huge disparity in model years. I knit using a lot of “fussy” yarns, substitute tuck wheels for the brushes usually on far right and left of image as viewed here to avoid problems sometimes caused by the bristles getting damaged and worn with use. Some people actually remove the same brushes altogether, but I have not had good results doing so. The three screws above the wheels on each side are used to adjust the space between the sinker plate and the gate pegs if needed. When the gap is too small yarn may get caught, when too great stitches may not knit off properly. Generally loosening the only the 2 side screws is enough to allow movement of the sinker plate in relationship to the gate pegs. It is helpful to have an old credit card or other “tool” to help hold the correct spacing while screws get tightened back up with carriage in its knitting position on the main bed.

This view shows the front of the sinker plate; the white plastic “arms” may be seen at the top of the image, 2 other distinct features on this model were the 2 metal pieces marked on the right

BTW: though some compatibility charts online list the 910 series as having thread lace capability, they indeed do not. I will try to find information on later models, and share here.
