Working with Images
Last updated Sep 9, 2004.
Working with Images
The .NET Framework has many facilities for loading, displaying, and manipulating images in many different formats. The formats that the Framework supports are shown in the table below.
| ImageFormat value | Description |
| Bmp | Windows bitmap (BMP) |
| Emf | Windows enhanced metafile (EMF) |
| Exif | Exchangeable Image File |
| Gif | Graphics Interchange Format (GIF) |
| Icon | Windows icon file |
| Jpeg | Joint Photographic Experts Group (JPEG) format |
| Png | W3C Portable Network Graphics (PNG) format |
| Tiff | Tag Image File Format (TIFF) |
| Wmf | Windows metafile (WMF) |
The Framework encapsulates the entire image handling functionality into two classes, System.Drawing.Bitmap and System.Drawing.Imaging.Metafile, that are descended from the System.Drawing.Image class. Metafiles are handled differently from the other image formats because they are fundamentally different: metafiles contain drawing commands whereas the other formats contain more traditional image data (color tables and pixel values). Encapsulating bitmap handling in this way allows you to perform the same set of operations on an image, regardless of its raw format. Rather than having different manipulation functions for every image type, the Framework converts everything to the internal Bitmap format so that one set of functions works with every image type. It also allows you to convert painlessly from one format to another.
