--- Comment #5 from Sven Claussner <scl.gp...@gmail.com> --- I investigated a bit and a look at the console output gave me some insights. On opening the File/Open dialog, a long list of file format messages is printed out, among them: mimeType "image/x-krita-raw" seen false swap extension order false description: "Camera Raw Files" patterns: ("*.nef", "*.cr2", "*.sr2", "*.crw", "*.pef", "*.x3f", "*.kdc", "*.mrw", "*.arw", "*.k25", "*.dcr", "*.orf", "*.raw", "*.raw", "*.raf", "*.srf", "*.dng") >>>>>>>>>>>>>>>>>>> "Camera Raw Files ( *.nef *.cr2 *.sr2 *.crw *.pef *.x3f >>>>>>>>>>>>>>>>>>> *.kdc *.mrw *.arw *.k25 *.dcr *.orf *.raw *.raw *.raf *.srf >>>>>>>>>>>>>>>>>>> *.dng )" On trying to open a CR2 file, Krita prints: krita.file: Couldn't create a valid graph for this source mimetype: "image/x-canon-cr2" Checking at system level (at least in KDE), the CR2 files are associated to another mime type than Krita expects. To prove this I added the new mime type "image/x-krita-raw" at system level and assigned the imaginary CR3 file extension to it. Then I renamed a CR2 file to CR3 and opened it in Dolphin with the Krita AppImage - et voila: Krita opens it in full size! Here are the correct mime types I got from the KDE file association tool: NEF: image/x-nikon-nef CR2: image/x-canon-cr2 SR2: image/x-sony-sr2 CRW: image/x-canon-crw x3f: image/x-sigma-x3f kdc:image/x-kodak-kdc mrw:image/x-minolta-mrw arw:image/x-sony-arw k25:image/x-kodak-k25 dcr:image/x-kodak-dcr orf:image/x-olympus-orf raw:image/x-panasonic-raw *.raw is a duplicate. Perhaps you meant *.rw2, which is image/x-panasonic-raw2 ? raf:image/x-fuji-raf srf:image/x-sony-srf dng:image/x-adobe-dng Tldr; : assigning the raw formats properly to their corresponding mime type should fix it. -- You are receiving this mail because: You are watching all bug changes.
