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 #{
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF000000000000FFFFFF
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF... etc.
or
>> img: load %image.gif
and:
>> 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 #{
789CAD90410A003008C3FCFFA7DD6583516CD5CDDC94A688EE1CDB8888E4C5BF
F3E8675D515ECD915BF1B1C3808A7FF6B8EBF88C8EFF7BFFC4FFB23C9B5987F2
959BDDD3A5E22F920B1DFF80030000
}
>> 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 1.2.10.3.1, but runs perfectly in 1.2.1.3.1
