Without installing windowscodecs via vinetricks, before opening an image, mouseover previews of an otherwise unseen sample image are displayed. After opening an image, it knows the size etc of what it's been asked to open, but the display of it is black. Similarly, the mouseover previews of the various effects are black. On saving, the file appears to be all black. After installing windowscodecs via vinetricks, it displays the iamges and mouseovers of it correctly. Saves are also correct. https://web.archive.org/web/20250919105142/https://nevercenter.com/camerabag...

Yes, sorry, there's about three things to report and the wrong title was pasted. Now edited.
Please attach +wincodecs wine log, as a text file.
Attached has the results of running a plain Wine install with env "WINEDEBUG=+windowscodecs" .. is that what you're after? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=58757 --- Comment #7 from Ian <superian(a)gmail.com> --- Thanks for the hand-holding. As well as the lines showing things like reading EXIF data are not implemented, there's one that sounds a likely candidate for this: 0128:fixme:wincodecs:copypixels_to_64bppRGBA Unimplemented conversion path 18. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58757 --- Comment #8 from Nikolay Sivov <bunglehead(a)gmail.com> --- Yes, that sounds important. Regarding metadata, we have some support for metadata blocks of various types. There is no support for XMP (xml-based metadata content), and also no support for what's called "policy expressions", which is what happens in this log - comma-separate names like System.Photo.xxxx. Presumably that gets translated to a query, depending on metadata format. Anyway, metadata support is unlikely an issue I think. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

That's not in 11.0-RC3, is it?
If it is, the problem remains.
No, these patches are not included in wine-11.0.rc3 because of code freeze. You would need to apply the patches manually and build locally if you wish to test them. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=58757 --- Comment #15 from Ian <superian@gmail.com> --- I think I have done that, via editing in the linked changes to a copy of the 11.0-rc4 source for converter.c and compiling that. Although I can't copy the resulting windowscodecs.dll files from the resulting build to a plain install of 11.0-rc4 and have it work (they are a couple of MB bigger than the 11.0-rc4 binaries - debugging info etc?) I can use the whole build to run and install CameraBag Pro 2026.0 in a new wineprefix. When I do that, I still get an all black image display on opening a JPEG, so it looks like it's not just the previously missing wincodecs:copypixels_to_64bppRGBA function that's the source of this. There's a different, but similar message in the windowcodecs debug.log: 0120:fixme:wincodecs:copypixels_to_64bppRGBA Unimplemented conversion path 13 Is that because adding the new case changed the path number or..?
