Hi there, over the past few months I have been working on a new version of gil's io extension. [...]. In-memory jpegs: If I get my jpeg data from somewhere other than a file, e.g. from some sort of database, or from an in-memory cache or an mmap()ed file, do you have a way to use it?
It is possible to read from memory or any other thing that can be treated like a stream. The read and write methods require a "device", there are already implementations for FILE* and std::streams: http://gil-contributions.googlecode.com/svn/trunk/gil_2/boost/gil/extension/... A device should provide {read|write,flush} and seek. It should be easy to implement one for in-memory images. kind regards Andreas Pokorny
