Summary
GDI+ Image class.
Description
Use this class to create and manipulate GDI+ Images.
The TGPImage class provides methods for loading and saving raster images (bitmaps) and vector images (metafiles). An TGPImage object encapsulates a bitmap or a metafile and stores attributes that you can retrieve by calling various Get methods. You can construct TGPImage objects from a variety of file types including BMP, ICON, GIF, JPEG, Exif, PNG, TIFF, WMF, and EMF.
