null, red, green, blue].
No. It's run-length-encoded. Just as well, since the text property
is what's stored on disk, and a 32-bit image with no compression
whatever would take up a ton of room. Take a look at the length of
the text versus the length of the imageData of a typical image object.
Wow, where is this in the dictionary?
I have tried setting the text of an image to some PBM/PGM/PPM formats
(P6 and P3 mostly, I think), but got no response to the image or
size. When I tried to subsequently export, I got an error.
Maybe something was wrong with my data.
I suppose if I could set one of these, I could still compress it by
exporting as something else and then setting it again.
Has anybody tried some of the simpler formats?
