OpenGL(Open Graphics Library)是用于渲染2D、3D矢量图形的跨语言、跨平台的应用程序编程接口(API)。 OpenGL ES (OpenGL for Embedded Systems) 是 OpenGL 三维图形 API 的子集,针对手机、PDA和游戏主机等嵌入式设备而设计。 OpenVG(Open Vector Graphics),OpenVG? 是针对诸如Flash和SVG的矢量图形算法库提供底层硬件...
法确认fb里的数据 i)cat /dev/graphics/fb0 > /sdcard/fb0,然后将/sdcard/fb0 >到另一台相同分辨率及相同格式的手机上,看图片显示是否正常 ii)使用irfanview软件显示cat /dev/graphics/fb0出来的raw数据,注意要正确设置分辨率及格式,否则显示花屏 iii)如果adb连接正常,可以使用豌豆莢等软件,查看fb中的数据是否...
Functions in thevgagllibrary have the prefixgl_*. To initializevgagl, the graphics context must be set. Example: vga_setmode(G320x200x256); gl_setcontextvga(G320x200x256); In this example, the context is set to the physical screen. The context can be saved (only the screen type, not...
