补充：c++ builder 与 windows  API经典范例

这种代码完全看不懂，先把过程照着wp写下来，之后慢慢 分析吧，首先字符 wrong定位到算法函数：

如图为主函数：

 

用exescope导出dump如图

于是写出脚本，拷贝别人的：

from PIL import Imagewidth = 200height = 150image_file = open('Data_1.bin', 'rb')data = image_file.read()image = Image.frombuffer('RGB', (width, height), data, 'raw', 'RGB')image = image.transpose(Image.FLIP_TOP_BOTTOM)image.show()image_file.close()

于是得到了这张图片
