Turned out not to need the offscreen buffer, just read_image() was perfect for what I was doing.

Reasonable, but I find lambdas and some other C++11 features to be major improvements that have been long overdue in C++, and particularly useful in UI code, and any new projects I start are likely to make use of C++11. This library uses a mixin to overlay the lambda-friendly interface without modifications to FLTK itself. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
