I am "brand new" to Revolution, my first contacts with hypercard-like tools also were my last: Toolbook on Windows, about 12 years ago. I am currently trying to get comfortable with Revolution - or, more precisely, with "Transcript" - to minimize the work needed to get cross-platform tools.
As a "starter" I plan to "port" some older tools I did in C, which read in JPEG files and parse the attached headers (JFIF etc) according to some specific rules, handling Photoshop-chunks etc.
I understand that rewriting the decoding in "Transcript" would be best to get a cross-platform version. I have to admit that I find Transcript extremely difficult to read, at least imagining a larger project with complex "parsing functions". Most likely this is a question of getting used to Transcript.
My question now is: I have browsed the documentation but did not find a detailed description about how to handle binary objects. So that is why I described my "test project" above: I need to read in a JPEG file (no display needed or wanted), eventually decode it into a bitmap memory area (I understand this decoded bitmap is available as an object after the JPEG has been read in, I found something about that in the docs). And I need access to all header chunks in the file, so I can parse them. I would love to have a "C-like" language for that, since I am used to that for about 20 years or longer, but learning something new may be fun :-)
Could someone here point me to the right place in the documentation where handling binary objects and parsing them is described?
Erm, and: Is there a plain text version of the docs? I find the short chapters and the help-browser (on Windows) some kind of unsuportive :-)
