WORK IN PROGRESS
A three-color per row sample test .
I am not interested so much in large scale images when trying to understand how things work and like to be able to predict the placement of yarn colors in my designs so I can have a matching color placement in the finished knit. I had played a bit with loading colors into the program and found their “working” depending on the placement in the color palette. Subsequently, I found the explanation online that the program needs a pattern image which is 8-bit greyscale, each color is coded in a range of the 8-bit values. So for 4 colors it would be 0-63 color a; 64-127 color b; 128-195 color c; 196-255 color d. It seems to be OK to give the image some color, so long as the gray component of the colors divides up as given. I began with a pattern using 3 colors, with one color absent in some rowsbut considering color placement and the program prompts to help avoid errors in color changes, I decided to try converting the original in a few colorways to indexed 3 color grey shades for testing
