Color patch image generator #9

Open hdznrrd opened 10 years ago

Create color patch images from histogram data to easily and visually evaluate intermediate data results

Histogram data to color patch image. Currently only works with fixed size images. Uses convert itself to do on the fly color quantization (-colors)

histbin_to_magickdraw.pl converts imagemagick histogram output to width-relative color patch draw commands which can be fed into convert again.

sh -c "convert -size 1280x50 xc:black $(convert  frames/01616.png -colors 16 -define histogram:unique-colors=true -format %c histogram:info:-|sort -rn|../histbin_to_magickdraw.pl) patch.png" && eog patch.png

Currently it produces results like this (original in background, color patch image in overlay, compositing done manually): sneakpeek
