Then

PHP has a surprising ability-you can use its server-side script to create dynamic graphics. This feature is based on the GD library, which is an ANSI C library designed by Thomas Boutell, which supports the addition of the library. Most common graphic file formats other than GIF files (although the library's designers have promised to add. gif support as soon as the LZW patent expires on July 7, 2004). PHP4

js| Create | graphics There is a technology that produces neat, fine-grained histograms in Java Server Pages (JSPs) that can be used as a reusable background. In order to achieve the purpose of reusability, you need to make the size of the graphics can be adjusted, you should also manage the straight square so that they do not cross the boundaries of the

You will then need to encode the graphic data into an availa

everything for us. Especially GDI + , Win32 Programmers should be very clear about Vc6 And Delphi5 , 6 , 7 ToIt is not easy to draw a window control with irregular graphics and a unique style. We need to return the current device pointer, map coordinates, and then call the standard Win32GDI Function to draw, and finally remember to release the device pointer and a series of memory cleanup operations, now . Net Class Library, we only need Onpaint Even

We look forward to consumers' active attention to bada, a brand new mobile gaming platform, because the powerful graphic API can implement 2D and 3D graphics. Programs that benefit from 3D graphics APIs include games, map visualization, user interfaces, cartoons, screen saver, etc. To meet the needs, bada APIs include OpenGL®ES, used for advanced embedded graphics
