How can I read/write an image in C++ using just boost/standard library?

Question

Is this possible? It doesn't matter what format the image is, but I have to be able to open it, read pixel data into some sort of array, create a new image using a modified set of pixel data.

Thanks!

Boost.GIL有一个很好的视频教程 ，向您展示如何以非常通用但高效的方式读/写和处理原始图像数据。

Answer 2

I suggest CImg . This library is extremely easy to use. You only have to include a header file in your code and set some parameters when compiling and that's it! I've used CImg with MingW and GCC.

Answer 3

You need code to encode and decode the formats you want to support. You can do this yourself (not really ideal/practical,) you can embed encoding/decoding libraries (like libpng, for example,) or you can embed image libraries like DevIL.

Boost seems to include some sort of image access library known as Boost.GIL . I really don't know much about it, though.

Answer 4

I suggest the TARGA image format for your needs. You just read/write a few values in a header, then the rest is an uncompressed array of RGBA pixel data. You won't even need Boost!
