knitwit

Create your own Winter Bash 2018 knitted image!

In addition to the usual hat challenges, Stack Exchange added a tool for making knitted images. knitwit is my attempt at a MATLAB tool to mimic the results, with a few extra options. Some sample images can be found in my answer to a Meta question where everyone was showing off their creations.

Usage:

KNITIMG = knitwit(IMAGEFILE) will load the image data in file IMAGEFILE and resize, pad, and recolor the image to create an output image KNITIMG that mimics what would be created by the Winter Bash 2018 knitting tool.

KNITIMG = knitwit(IMAGEDATA) will use the image data in IMAGEDATA instead of loading from a file. IMAGEDATA must be an N-by-M-by-3 matrix.

KNITIMG = knitwit(..., 'PropertyName', PropertyValue, ...) will modify how the images are generated based on the property/value pairs specified. Valid properties that the user can set are:

• 'BackFill' - A logical value determining if the code will attempt to identify a background solid color (abutting the borders) and fill it with the default blue background value. Default is FALSE.
• 'Dither' - A logical value determining if dithering will be used when performing color quantization. Default is FALSE.
• 'AddKnit' - A logical value determining if the knit pattern will be added to the image created. A value of FALSE will create a resampled, color-quantized image that can be uploaded to the Winter Bash 2018 knitting tool to add the pattern. Default is TRUE.
