如何在Delphi6和7中使用GDI 函数?

http://www.progdigy.com/ Download GDIPlus for Delphi 5/6/7. http://www.progdigy.com/download/gdiplus.zip Download GDIPlus Redist (Not needed with WinXP.) http://download.microsoft.com/download/platformsdk/redist/3097/W98NT42KMeXP/EN-US/gdiplus_dnld.exe Download GDIPlus documentation. http://www.progdigy.com/download/gdiplusdoc.zip I've tested all functions of GDIPlus API for Delphi 5/6, so i'm sure this API is fully functional. You will find 82 sample applications to learn how to use most of GDIPlus features. GDI is a new graphics subsystem for Windows and provides a new set of graphics APIs for rendering 2D graphics, images, and text. GDI is the only API for drawing in the .NET Framework, but in Delphi it is a complement to the current GDI to provide more advanced rendering capabilities. Here's what you get with GDI : antialiased 2D drawing, alpha channel support, universal transformations and floating point coordinates, gradient brushes, cardinal splines, scalable regions, and a new programming model. The GDI feature can be easily redistributed. GDI is standard on Windows XP. For Windows 98, Windows Me, Windows NT?4.0, and Windows 2000, you can simply copy GdiPlus.DLL into your app's directory. GDI uses a different programming model from GDI. Instead of selecting brushes and pens into a device context, in GDI you pass the pen or brush into every drawing command. Graphics elements are no longer drawn with both the pen and brush together; they are outlined and filled using separate functions (such as DrawRectangle and FillRectangle).
