[REBOL] Compressing image data (bugs?)

From: henrik::webz::dk at: 4-Dec-2003 14:57

Hi, all Sometimes image handling baffles me a bit. I want to embed a small 2-colored image in the script for use in a button. It would of course be nice to compress it to a chunk of binary data. However, I always lose the size of the image when doing something with it, which is highly impractical. If I have:
>> img: make image! [16x14 #{
>> img: load %image.gif
>> to-image decompress compress img
the size is lost, but the binary information remains. So in order to keep size information, I would have to:
>> img-data: to-binary decompress #{

>> img2: make image! [16x14 img-data]
But, img2 contains just 2 bytes set, and they are random, for each time I set img2 by the above line. The remaining bytes are zero. It looks like a bug? But:
>> length? img2
gives the correct length though. BTW: Just found by playing around that:
>> to-image to-binary img
Crashes Rebol, but runs perfectly in Regards, Henrik Mikael Kristensen
