如何将像素数组转储为png？

Question

I'm on MacOSX.

I have read out an image, as

char image[WIDTH][HEIGHT][3]; // row, col, rgb value

Now, I want to dump it out as a png file. What is the quickest way to do this?

Answer 1

You should use libpng . I don't have a Mac, so I can't tell you if it's already pre-installed, but it should be! :-)

Answer 2

您可以使它成为一个流并将比特流写入图像对象，然后您可以将图像对象保存为PNG。
