how to load image and detect greylevel for each pixel?

[copico]

Hi, I am doing a project doing image processing using C++. But I dont know how to load image (jpg or bmp) into MFC. And I need to make the image into graylevel image. also I need to get the graylevel of each pixel. Someone introduce me VFW, but I still cannot find out how to load image and get information of it... really need your help... Thanks...:sigh: coding, coding, still coding...

have a look at the cximage library here on cp ... it will do all that and more ... and u can study the source code to see how it does it too ;)

Check out the CBitmap class and (H)BITMAP structure on MSDN. You can use the CBitmap class to determin the RGB color of each pixel. Hope this helps. "If I don't see you in this world, I'll see you in the next one... and don't be late." ~ Jimi Hendrix

If you want to make advanced image processing application; - First use DirectDraw to proceed display images. - Learn .jpeg, .bmp file format - Learn .bmp, .jpeg file compression decompression. ICImageCompress(...) and ICIamgeDecompress(...) defined vfw.h will be helpful
