Wrong. TIFF is a container format. The contents in a TIFF file can be compressed or uncompressed, losslessly or lossy. PNG/MNG is a container format. It can also have compressed or uncompressed, losslessly or lossy. DJVU and PDF can also contain compressed or uncompressed chunks, losslessly or lossy. > So, not only is > supporting lossless file formats good for WikiSource texts and good for > image restorationists, it is also good for our future negotiations with > museums and galleries. TIFF support is good for future negotiations because it means that we don't need to argue with them about which file formats are better, or concern ourselves with the feasibility of transcoding large collections. -- John Vandenberg _______________________________________________ Commons-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/commons-l
