need advice on parsing image data

file first - anyone - please? Using your example, you can say im: load r/7/content view layout [image im] or even view layout [image load r/7/content] Cheers -Larry

Might be too easy, but why is load even needed at all? if in this example, r/7/content is set, known, and in memory. Simply specifying: view layout [image r/7/content] Should be sufficient. I still have yet to wrap my head around rebol. I know it is portrayed as an 'easy to learn, thought like' language but some things like this still stump me. To me, the above layout line would be the way I would think about writing it in human fashion.

I'm using 'read-io to retrieve the POSTed data. There is no /binary refinement for 'read-io. Since 'read-io is a "low-level read from a port" according to 'help, isn't it already retrieving the POSTed data in binary form? Ryan C.

I'm no expert but here's my thinking. 1) The data returned from the post should initially be treated as binary - because you have image data that is binary and has not been encoded. So what I did was use read/binary to get your post-data file. I don't know for sure, but it is possible some clients may upload the file data in a different encoding like Base 64 rather than straight binary. So you may need to handle the case where a content-transfer-encoding header is given. 2) Though you data is binary doesn't mean you can't parse it like a string. Just remember to use /all refinement of parse. I already had some mime type handling stuff for emails. So I changed around a little bit to handle your file as well. It is very possible I still haven't handled the RFCs properly but it seems to work at the moment. Using Rebo/View Try this script - The view part is just to show that I succesfully got your image data. do http://www.codeconscious.com/rebol-library/message-tools.r post-data: read/binary http://www.fargonews.com/post-data r: decode-mime-parts mime-parts? post-data ---------------------------7d1a92c9014c write/binary %tf.jpg r/7/content view layout [image %tf.jpg] BTW I'd like to know how to display the image without having to write the file first - anyone - please? Hope it helps you.
