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 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 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 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 window, go to file export menu, choose 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 color 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 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, go to image, mode, click on convert

Open image_ scale window; use image scale tool, clicking once again on selected repeat area

Adjust numbers to 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  row that need to be inverted and repeat outline, and use navigation bar to enlarge for easy selection individual rows with crop tool

After selecting desired row with the rectangle select tool go to colors_invert, seen here for first row of color 2, repeat for length of motif. The result is suitable for use with double length KM built in features, and color changer. The black squares represent programmed pixels in download, or  what is drawn  on mylar/ punched in 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 window for scale tool, type correction to numbers if needed, click on scale , autocrop to selection for export in desired format or screen grab and print to 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 card
