Except it still is puzzling that the imagedata would be so obviously corrupt while the image looks fine. See if you get good imageData the second access or after getting 'the text' of the image. If so, use that as a workaround. This sounds familiar. Maybe you should bugzilla this, especially if you are willing to supply RunRev with an example image. Check the image bugs; this might be there, but I think this is different. I'm going to do a rash of image checks in the next beta, so if bugzilla is a bother, I'll look for this then. I think I have seen Revolution gag on some gray PNG files and display a squished pink image. Maybe some gray formats are a problem.

imagedata problem Ken Ray
Does anyone else have this experience? -- I'm trying to analyze the imagedata of a whole bunch of grayscale images. The problem is that the imagedata for almost every pixel is: 0,191,191,191 or 0,85,85,85 or 0,200,200,200 Each image has its own favorite number and it seems to make no difference whether the pixel is actually white or black or gray. On the other hand, there are parts of the image (usually the far left side or the far right side) where believable numbers suddenly appear. These images are bxw tiffs that I turned into transparent gifs in GraphicConverter. But I don't understand: if the imageData is corrupt, why do the images look fine? Any ideas how I can figure out the correct imagedata? Maybe I'm mistaken, but I'm expecting to see white pixels listed as: "0,255,255,255" and black pixels: "0,0,0,0" Thanks.
