There are a couple issues that complicate this in general. The parameters needed to process the stream need to be parsed and they can be far away. There are many stream filters (some complicated compression) and they can be nested. I looked at a corpus of PDF files and, yeah, a several are used in practice. However, if one needs to parse the output of a specific program or a specific model of a scanner, then the work to do parsing in LiveCode is a lot less. I hope that makes sense; I'm a little under the weather today.
