如果你想创建一个程序像OmniPage一样，你有一项艰巨的任务。您在图像文件中看到的字符只是由称为像素的点组成，没有ascii字符。此外，图像文件格式非常难。 HTH --Sam

If you are trying to create a program like OmniPage, you have an enormous task. The characters that you see in an image file are just composed of dots called pixels, there are no ascii characters. Plus, image file formats are pretty tough. HTH --Sam
