这是为微型GUI编写的2D位图处理代码 贴图(选区贴图,半透明贴图,alpha贴图) 直线(直接画线,异或画线,透明画线) 裁剪(凸四边形裁剪,线段裁剪,覆盖分割) 变换(平移,缩放,错切,旋转,对称) 所有代码都经过彻底调试和初步优化了 采用标准C语言编写,linux-gcc编译调试

图像变换包括旋转90、180、270，缩放，水平镜像和垂直，裁剪-90,180,270 transform images, including rotation, scaling, horizontal and vertical mirror, cutting

包含了五个算法源码，能实现裁剪，平移变换，椭圆，填充，DDA，旋转变换，BresenhamLine MidBresenhamCircle-Including 7 algorithm source code, the graphics system to achieve a variety of graphics capabilities, including the transformation of filling, cutting, DDA, translation, rotation,

基于直方图的水印嵌入和提取实现，各种水印攻击，如重抽样，加噪，滤波，尺度变换，局部裁剪-Based on the histogram of the watermark embedding and extraction to achieve a variety of watermark attacks, such as re sampling, noise, filtering, scale transform, local cropping
