说明： 32位图像处理库delphi简单实现
TBitmap可以设置 ［pfDevice, pf1bit, pf4bit, pf8bit, pf15bit, pf16bit, pf24bit, pf32bit, pfCustom］9种格式，这里为了处理32位图像只用了pf32Bit。 (32 image processing to achieve the delphi simple tablet can set [pfDevi ce, pf1bit, pf4bit, pf8bit, pf15bit, pf16bit. pf24bit, pf32bit, pfCustom] formats, here to deal with 32 images used only pf32Bit.)
