Hi Thomas,
I was looking at export image late last night without much success.
If one exports to a variable and then sets the imageData to the variable
it comes out as a mishmash.
I looked into your suggestion of "optimized" this morning and it complained
about the syntax. I found out a couple of things to make it work.
1. The term optimized is in the wrong position in the dictionary.
2, Exporting to another image container instead of a variable works.
If you use as the dictionary suggests:
export image to {file filePath | container} as {gif | png} with colorCount
[optimized] color palette
so:
export "image1" to tImage as png with 16 optimized color palette
doesn't work.
If you use:
export image "Image1" to image "Image2" as png with 16 color optimized palette
it works!
Unfortunately according to the documentation, it won't work under iOS, so I
guess
it's back to the drawing board.
Any other ideas?
Thanks,
Rick
