image loading with windowscodecs
by Vincent Povirk July 9, 2009

July 9, 2009

So I've been working on an implementation of windowscodecs.dll (Windows Imaging Component). This is a Vista/.NET 3.x API for manipulating image data. To the best of my knowledge, only 2 programs currently use it, and I'm not running either one. We're not likely to see it used by real programs in Wine much, since there's no redistributable. A program using it would have to require Vista or .NET 3.0, or require users to download it manually. It's documented here: http://msdn.microsoft.com/en-us/library/ms735422(VS.85).aspx Adding this dll will not increase compatibility, at least not directly. It will, however, provide Wine with a single component that can be used by any dll or program that needs to load or save a raster image. All of the code for png, gif, jpeg, etc should be migrated into this dll. If we need any image formats not supported by native, we can implement them as Wine-specific extensions. We need to do this because oleaut32 (the current home of image-loading code) sucks. I have been told that the libpng code should not be duplicated throughout the codebase. I need features in gdiplus that oleaut32 does not provide, such as access to the image dpi and metadata, and the ability to save images. In fact, much of the gdiplus image/bitmap api matches WIC 1:1. On Windows, gdiplus is known to be able to use WIC extensions to support new image types, so in theory it should use WIC (though this probably won't matter any time soon). I'm told that image loading is also useful for d3dx9 dll's. The WIC api is well-designed in my opinion and should be able to provide any operations needed by other components to load/save images. The next step is to implement the image types needed by oleaut32 and start using WIC to load them in olepicture, starting with BMP. To that end, I need a good test program. I need to see what kind of BMP files currently work (I suspect that many are broken) and what kinds will work if I replace the BMP-loading code. This will tell me at what point I can make the change without introducing a regression. After that, I'll need to do the same thing with the other file types. So I need a general-purpose image viewer that uses either gdiplus or oleaut32 to do its image loading. Does anyone know any? -- Vincent Povirk

Re: WineD3D: Check if GL accepts 4 component specular colors

Actually, while I'm at it, you're also missing ENTER_GL()/LEAVE_GL() calls in match_allows_spec_alpha(), and you should document that it depends on the caller to do context activation.

For example, 3 component specular color will trigger the FIXME with this code. Also, EXT_vertex_array_bgra adds GL_BGRA as a valid type/size parameter for glSecondaryColorPointer(). Just test for "type == 4" and handle it according to the quirk being present or not. Combinations that are always invalid, like e.g. 1 or 2 component data should already have been filtered by declaration_element_valid_ffp().

Can someone tell me what's going on on this page http://source.winehq.org/transl/lang.php?lang=009%3A00 ? If you click on the bottom links (locales) I see a message "Invalid resource file". Does this mean the resource file doesn't exist, or is there a little oops in the links? Thanks, Ken.

'handles' is not initialized, moreover the number of passed handles is 0. MsgWaitForMultipleObjectsEx() works just fine with '0, NULL' combination. -- Dmitry.
