ImageData works well in my tests.
ImageData is working for me too now, I must have screwed up my intial tests.
I think I've got the rest of it figured out too, after a clue from Scott
Raney. It all depends on the paintCompression property, which is both a
global property and an image property. The default is "rle", which
doesn't work with "put img 1 into img 2". Putting an image's contents
into another image only works with jpeg, gif, or png images ("streaming
image formats".) So, the following does NOT work:
1. Take a snapshot. -- this img is in "rle" format by default
2. Create an empty image
3. Issue: put img 1 into img 2 -- fails, because the paintcompression is
"rle"
However, for imported images, MC retains the native compression format.
If I import a gif, the image's paintcompression remains "gif" even
though the global property is still "rle". If I set the global property
to "gif" as well, a new, empty image will also be in "gif" format. This
DOES work:
1. Use the "import paint" command to import a gif image -- or jpeg or png
2. Issue: set the paintcompression to "gif" -- sets the global storage
format; this is the key
3. Create an empty image -- which now will also be in "gif" format
4. Issue: put img 1 into img 2 -- WORKS

I must not have had the second image size correct in my first test, since now that I'm specifically creating an identically-sized new image, the "imagedata" method does work.

What platform are you trying the "put img 1 into img 2" on? An update: I imported a different (jpg) image. This one works when I set the imagedata of a blank image to the imagedata of the imported image. Then I took a snapshot, and that also works when I move its contents using imagedata (both rects are the same.) However, neither image works when I use "put img 1 into img 2". Image 2 remains empty with a data size of 0. My original test image does not work with either command, but it is from a very old stack and I don't remember what its original format was.

Re: Moving image contents
Hi Jaqueline, Both of the following fail for me: put img 1 into img 2 works fine here OS X MC 2.5/RR 2.0.1. set the imagedata of img 2 to the imagedata of img 1 If i remember right, the trick is here to have 2 images with identical height/width to make it work. So you could try to set these props of img 2 BEFORE you set the imagedata... ... set the height of img 2 to the formattedheight of img 1 set the width of img 2 to the formattedwidth of img 1 set the imagedata of img 2 to the imagedata of img 1 ... Tested and works :-) Can anyone else get these to work? I get either nothing in the first case, or visual garbage (and a likely eventual crash) in the second. See above... Hope that helps...
