I cannot remember exactly why I did not choose image3 for i/o,
possible reasons are: I never intended to use quicktime mov and the 64
bit version of image3 dll was not available. So I rip individual
verbs from image2/image3 into my utility script such as image_wh and
image_resize. I also read picture, lighten it, and use glpixels to
set it as background image.
lighten=: 1 : 'm+<.0.5+(255%~255-m)*y'
lightenb=: 1 : 'a.{~m+<.0.5+(255%~255-m)*a.i.y'
although hls should be more accurate, but this should serve the
purpose.
Ric have already demonstrated data read using platimg is equivalent to
that from image3. In summary I view image3 as a command-line version
of photoshop, and use platimg just for input/output.
