Automated shapes across rows of knitting using slip stitch only reviews several methods to automate/ program short row techniques.
BW repeats may have stripes of color planned and added by simply changing yarns in the yarn feeder in the selected areas.
A recent FB comment asked the question as to whether it is possible to automate intarsia using img2track downloads.
Short row “intarsia” can be executed with manual needle selection following charts, or as an easier, viable option using a knit radar and with shapes illustrated on garment pieces, which can follow the simple geometry seen in the hand selection methods, or graduate to the degree of complexity the knitter has the desire and patience to execute.
These posts illustrate simple shapes and the breaking down of more complex ones.

The Silver Reed electronic intarsia carriage was briefly available as an accessory for knitting complex intarsia designs with automated needle selection.
The yarn is placed and used in the same manner as when using the Brother intarsia accessory, but note that there are now multiple needle positions and selections for the 4 types of intarsia offered.
I gave away my standard intarsia carriage, so I cannot speak as to whether programming a design, placing yarn in selected needle groups manually as above, and bringing them all to the required position for the carriage to make successful passes would be a viable alternative.
These images are from the E6000 Passap manual, alongside the electronic repeats, which are mirrored on the front face of the knit.
The accompanying technique recommendations.
Without a Passap, and the discussion being on Brother electronic knitting, starting with duplicating one of the Passap designs and thinking it through, the 32X28 2-color repeat,
doubled in height to 32X56,
color separated for 2 color DBJ with each color in each design row knitting twice by color inverting every other row and doubling the height once more, to a final repeat of 32X112,
mirrored for use on the 930.
End needle selection must be canceled.
The pattern setting in the knit carriage is for slip-stitch in both directions.
The first preselection row is from right to left, with color changes every 2 rows using the changer on that side.
There will be a yarn ends to weave in, as at the start of any intarsia design.
Since each color knits for two rows, eyelets are formed at the color changes, familiar in short row designs. If bothersome, the size of the eyelets could be reduced.
The pattern was tested on 32 stitches and for 132 rows. At any point, more colors could be introduced for horizontal striping color changes.
When the yarn traveled across multiple stitches before being picked up, the resulting floats were hooked up every third needle on the same color stitches before knitting the second pass with it.
Central designs are more problematic to execute and, if not very wide, may knit more easily as single FI motifs, with wrapping at the sides, and latching up floats as needed.
Img2track will separate for 3 and 4-color designs.
This first attempt was a failure and reminded me why I love/hate the single bed color changers.
Aside from the changer and sinker plate crankiness, the colors, as they were carried up the left side, would twist around each other, forming floats to the next selected group.
Img2track selects colors based on the number of cells that are represented for each in the first design row, hence the sequence is blue, yellow, red.
The test image, 32×28, was doubled in height to 32X56.
I prefer to start short rows from the right.
Aiming for a similar attempt with the automated version, the image was mirrored horizontally for use on the 930.
The first preselection row is toward the color changer (remember to change the setting when the carriage is on the left to slip stitch). ![]()
This was a day when everything that could go wrong had. In addition, color #3, the red, catches on the left side before traveling to knit the narrow center band of color for no reason I could immediately fathom.
What the manual has to offer in terms of threading the changer.
After the knitter, accessory, and the machine got a break, analyzing the order for color changes made by the img2track, was reminded that selections are made in order of the number of cells representing each color in each design row, making the red, color 3, the selection for the center shape, catching that color on the left.
To eliminate that problem, one solution is to use a second carriage to select and knit the center color, operating from the right side of the machine, using rails and making sure each knit carriage clears the belt before the second carriage operates from the opposite side.
The programmed repeat stays the same.
This particular design has some jumps in the number of needle sequences that form long floats. They can be managed as one would in FI, i.e.
The resulting test swatch.
Devising a manual color separation to work cleanly with a fixed 1,2,3 sequence, the full repeat was cropped to 32X48 pixels in height, with each color in each design row still occurring X3, and the result was mirrored for execution on the 930.
Using ArahPaint, the process shown charted in progress:
The double height rendition, second from the right, with the white color locked, can have all other colors filled with black, as seen in the charted repeat on the far right, finally programmed as FI in img2track.
Missing out on the prompts for color changes is not a loss. It is easy to see which colors should knit next, with #1, red, starting on the far right, followed by the dark color, 2, for the center shapes, and then 3, the yellow/orange.

and the proof of concept swatch.
A convoluted approach: DAK Method C, if you have access to a screen grab of the template can convert it manually to a BW PNG, which may work with img2track, the double-length switch will need to be used in Japanese knitting machines. The DAK jacquard choices. 
If the goal is to use the technique in large knit pieces, then design repeats that tile properly can be used.
Encountering limitations to automation: a 20X20 repeat drawn using the pencil and straight line tool,
checked in repeat, 60X60,
filling in diagonal lines,
isolating a new 20X20 repeat,
doubled in height to 20X40,
color inverted for use on the 930,
and finally color separated, 20X80.
When using a repeating occurrence of the width of groups of each color in programming the final piece, there are some related problems: as selections are made and repeated across a row of knitting, the color being carried skips the non-selected needles, forming floats. Using the end needle selection on the carriage to catch yarns when needed at the side edges will throw off the repeats, as seen in the photo. End needles in work will also knit an extra stitch on either side of the non-selected needles, changing the intended groups of 8.
Returning to hand selecting needles, it becomes easier to add colors as well; there is no need to mirror the chart. The knitting sequences are numbered, and stitches are brought into hold after several rows of base knitting/ waste yarn.
To maintain straight side edges, it is best to chart the repeat in full. The original sketch can represent single rows of knitting, but short rows will be executed with each color making 2 identical passes, resulting in the familiar eyelets, and elongation of the design.
Color changes can occur frequently, limited by patience, yarn availability, and the knitter’s willingness to deal with lots of yarn ends.
The initial charted repeat is 40X40 pixels in width and height, and will tile correctly if larger pieces are planned or if longer pieces in a fixed width are the goal. ![]()
My swatch was knit with randomly grabbed yarns of my stash, in multiple thicknesses, not the best choice for the final pieces, resulting in some distortion along the diagonal lines.
All stripes are 8 stitches in width.
Most of the movements are needle one out on the left, one needle in on the right, except when small starting or ending triangles at the top or at the bottom of the diagonals are present.
When the top of the planned test is reached, stop on the right side when the last row of 8 stitches occurs for that color is reached, bring the group out to hold, make a free pass to the left, bring the next selection of needles to work, and continue.
Check stitch counts before returning to the left to pick up the next color.
Errors may not be noticed immediately, i.e., in the purple stripe.
If ends are woven in, try not to pull on them; allow for some ease to keep that last row cleaner, all easier to manage with thicker yarns than those in this swatch.
There is an accessory called an intarsia yarn brake.
While it was in my stash to demo in teaching days, I much preferred bobbins for personal use. Some knitters, as with all other accessories, find it useful. If possible, check reviews and take one for a test drive before making any purchase.
These are suggestions from published sources on how to deal with stitches in holding position, often found in conjunction with shaping shoulder slopes. Wrapping needles adjacent to shaping reduces the size of the resulting eyelets where the same row is repeated twice.
The Brother Techniques Book is a wonderful resource; their suggestions on partial knitting are on pp. 44-47, their illustration for managing those floats when moving by multiple needles, possible on both sides of the piece, harder to bring to the front if the pattern is automated and programmed for use with the slip stitch setting.
The angles and size of the shapes can be varied, straightforward to program if only two colors are used in the intarsia concept, but there is also the possibility of changing colors every 2 rows to create horizontal stripes that interact with each other, forming secondary striped interacting shapes.
The next rabbit hole will be exploring short rows, automated when possible, while making stripes intersect in shapes that go round, a return to “doilies”.
