Please note that the source code explicitely references the IMAGE category. Enter IMAGE, and then enter a unique id to reference the pic. At insertion time, VisualStudio prompts for a category name since obviously those file extensions are unsupportedi in version 6.0. In the open dialog, select the *.* file types in order to show. rc editor, righ-click on Resources, and choose Import. ![]() This is followed by the reproduced MFC implementation from PaulDiLascia, and then again a sample showing how to use it.Ī pic needs to be inserted in the. In the remainder of this article, I provide the code for the WIN32/GDI implementation, then a sample code to use it. So I decided that, because my needs are such that I don't want any MFC in my code, I have rewritten the CPicture class with raw WIN32/GDI calls. Igor, someone I have met in codeproject forums, was kind enough to show me a link to an existing MFC sample implementation for it, basically a single class called CPicture. ![]() Offering alternative image formats, for cases where certain formats are not supported. Cropping or modifying images for different media conditions (for example, loading a simpler version of an image which has too many details, on smaller displays). In addition, the interface manages the rendering by passing it a device context. Common use cases for : Art direction.So, while MSDN limits the capabilities of the IPicture interface to BMP, ICO, CUR and WMF pics, actually this interface supports non-animated GIF as well as JPEG pics. OLE/COM provides an interface I have even played with last year, and the MSDN documentation is kept so out-of-sync that it doesn't even mention what the IPicture interface really supports. Regardless the GIF licensing issues, which have ended up in the united states since june 2003, I have always relied on third-parties because of the lack of such thing along with the WIN32 API. Why such a thing in first place? Simple, I am used to have a dependency on a GIF read/write third-party library and a JPEG read/write third-party library whenever I have to use non-flat *.BMP files. Both MFC and non-MFC source code is provided as to fit the largest requirements. This article provides source code in order to read and display JPEG and GIF pictures using no third-party library at all. ![]() Loading JPEG and GIF pictures Loading JPEG and GIF pictures
