--- Comment #4 from Anselm Lingnau <anselm+...@anselms.net> --- Well, the EXIF standard (http://cipa.jp/std/documents/download_e.html?DC-008-Translation-2019-E) says, in section 4.5.4, “Basic Structure of JPEG Compressed Data”: “Compressed data files shall be recorded in conformance with the JPEG DCT format specified in ISO/IEC 10918-1, with the Application Marker Segment (APP1) inserted. APP1 shall be recorded immediately after the SOI marker indicating the beginning of the file”. This means that according to the standard, a file that has an APP0 (JFIF) marker segment immediately after the SOI marker and the APP1 segment after the APP0 segment is in error. I would suggest that Digikam should either omit the EXIF information altogether when it writes JFIF (ff d8 ff e0) files for inclusion in e-mail, or else do it like it says in the relevant standard, i.e., leave out the APP0 marker segment and write only an APP1 segment with EXIF data. I wrote a patch for jpegexiforient, but the jpeg-turbo guy said he wasn't going to take it because it would encourage sloppy implementations of the standard. I can see where he's coming from, but I'd also like this problem fixed. I'd much rather not see this devolve into a game of finger-pointing where everyone says the mistake is on the other side. -- You are receiving this mail because: You are watching all bug changes.
