image conversion
[1/8] from: th72:dds:nl at: 2-Mar-2006 14:16
Hello List,
I have a problem...
Is it possible to convert binary data to an image?
I use an external program (via call) to produce a image. I can capture
the image via call/output but then I am lost.
Out is then a string! type like this:
{GIF87a
^A+^A=91^-^-=FF=FF=FF^-^-^-=E5=D3=C9^-^-^-,^-^-^-^-
^A+^A^-^B=FF=84=8F=A9=CB=ED^O=A3=9C=B4=DA=8B=B3=DE=BC=FB^O=86=E2H=96=E6=89=A6=EA=CA=B6=EE^K=C7=F2L=D7=F6=8D=E7=FA=CE=F7=FE^O^L
=87=C4=A2=F1=88L*=97=CC=A6=F3^-=8DJ=A7=D4=AA=F5=8A=CDj=B7=DC=AE...
Can I convert this to a REBOL image type so that I can display it with view?
I tried converting it to-binary, but no succes...
Thanks
Tim

Hi Tim,
If your image is string!, use following code:
>>image: load to binary! image-in-string
if your image is binary!, it's even easier:
>>image: load image-in-binary

Thanks Boleslav,
I can see now something that looks like an image, but it's distorted. It
works oke when I first save the data and then load it again. I think
something goes wrong with the line termination characters. Thanks so far.

BTW how to output image from script to web browser? I tried simplest way by
using content type header for image and then printing out binary string, but
it did not help.

binary: make binary! 4000

Then output the binary.

Mmm.. Maybe you can set the console to binary mode
(have to look that up somewhere...) and then hopefully
the output string from CALL won't be touched.

That should work....something like:
binary-data: ---make or load your image here---
print "Content-Type: application/octet-stream"
print newline
set-modes system/ports/output [binary: true]
insert system/ports/output binary-data
quit

Here's what I use (and this works):
data: read/binary %/some/image.jpg
print "Content-Type: image/jpg^/"
write-io system/ports/output data length? data
