我发现无法相信你看到了所有。在VB.NET中，您可以使用GetPixel方法获取RGB值。它是一个JPG是无关紧要的，除了你的图像会降级，bmp中纯白色的区域会变成jpg中的许多白色阴影。这是有损的。



如果你使用C＃dll，你可以使用代码项目中我的图像处理文章中说明的直接像素访问方法。

I find it impossible to believe that you looked at all. In VB.NET, you can use the GetPixel method to get RGB values. That it''s a JPG is irrelevant, excepting that your image will be degraded, an area of pure white in a bmp will turn to many shades of white in a jpg. It is lossy.

If you use a C# dll, you can use the direct pixel access methods illustrated in my images processing articles here on Code Project.
