Once have enabled Direct2D support in an MFC application, there is no sweat to load an image from a file, by using one of CD2DBitmap constructors. Unfortunately, we cannot find a CD2DBitmap method to save it into a image file (something similar to CImage::Save or Gdiplus::Image::Save). No problem, we can try to do it ourselves. … Read more
In an older article, I presented a function that enumerates Windows Imaging Component codecs. Recently I had the idea to make a set of WIC Interfaces wrapper classes for easily enumerate and get info about all types of WIC components: bitmap decoders and encoders, metadata readers and writers, format converters, and supported pixel formats. Here … Read more
A graphic file can store additional information abaout image (camera model, camera manufacturer, date and time, etc). Windows Imaging Component (WIC) provides interfaces which allow dealing with image metadata. Basically, for reading metadata we need an IWICMetadataQueryReader instance to call its GetMetadataByName method. The first argument of GetMetadataByName is based in Metadata Query Language and is composed by … Read more
Once having a WIC (Windows Imaging Component) source, we can render it by using GDI, GDI+ or Direct2D. There are many examples over the internet including MSDN Library that describes how to perform this. This article describes how to use WIC Wrapper Library, which is designed for using WIC without worrying about directly deal with COM interfaces. … Read more
A previoius article extends CFileDialog MFC class, in order to make a File Open or a File Save dialog that automatically filters files, according to available WIC (Windows Imaging Component) codecs. This article presents how to show a similar File Open dialog using IFileOpenDialog interface. This way, it can be used not only in an … Read more

Download: Example 2: Using wic::ImagingFactory::CreateBitmapFromHICON and wic::Bitmap The following example is close to the previous one, except that it uses wic::ImagingFactory::CreateBitmapFromHICON to display an icon … Read more
I’ve begun writing a series of wrapper classes over WIC (Windows Imaging Component) interfaces, that can easily be used in MFC, ATL, or Win32 applications without worry about directly dealing with COM interfaces. This first version contains basic operation for loading, scaling and converting source image formats that are supported by WIC. Download: WIC Wrapper … Read more
A previous article showed how to enumerate WIC (Windows Imaging Component) codecs, that are available in system. Now, let’s use the codecs list in order to make File Open and File Save As dialogs which are dealing with WIC-compliant image files, i.e. having “File of type” filter list according to available WIC codecs (see the images, below). CWICFileDialog class … Read more
