You most definitely do not want to run the image-based algorithms like alpha blending or the Porter-Duff composition modes in inline template code. You want highly optimised, vector versions of them using the resources of the CPU and GPU, and not inline. You could call it a quality-of-implementation issue and allow the implementation to use extern templates for the known and common image formats. But I suggest that we *first* get the algorithms for what really matters settled down, then we figure out how or if they should be made generic. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
