Hi to all, the new gil::io extension is ready for review. The release candidate is available from the link below containing the header files, tests, and documentation. There are jamfiles available to run the tests and to compile the documentation. http://gil-contributions.googlecode.com/files/rc2.zip This file is almost 9 MB due to the amount of test images I'm using for testing. If that's a problem I can certainly create a slimmer release candidate. A lot of things have changed for this extension but also a lot of things haven't. The interface is more or less the same. But the list of features has been grown by a lot. For instance, all formats support now in-memory read and write. The tiff extension supports a lot more formats to be read and written. n-bit images are now supported for all formats that include those. etc. etc. Right now the lib is called gil::io_new but once it's accepted it will be renamed to gil::io. Of course, I'm open for all kinds of input, critiques, and insights. Thanks a lot to all people who have helped me on this release! Regards, Christian
