Image Color Downsizing

[Thomas McGrath III]

Rick,

Have you checked out "export with palette" in the dictionary? It works on the palette of the image which could be set to 16 color count?

export "image1" to tImage as png with 16 optimized color palette

If the optimized palette form is used, then a palette with the colorCount colors will be generated that does its best to approximate all the colors present in the image. The image will be color-matched to this palette before export. If colorList is not specified, a 256 entry palette will be generated. 


export with palette

Type: command

Syntax: 
export image to {file filePath | container} as {gif | png} with standard palette
export image to {file filePath | container} as {gif | png} with optimized palette
export image to {file filePath | container} as {gif | png} with colorCount [optimized] color palette
export image to {file filePath | container} as {gif | png} with palette colorList
