Hi guys,
Is it possible to save a portion of a sprite as an image (ex: a .png file) to the hard disk?
If yes, a code snippet will be much appreciated.

Yes.

Check the Image Functions in my signature.
Initially you can use GetSpriteImageID() to get the image ID from the sprite then from my functions, the function you want is CopyImageAreaToImage() which will create an image from a section of another image.
Then use SaveImage() to save it to disc.

I noticed that in the function
Quote: "CopyImageAreaToImage"
the target image must exist. How can I create the target image?
I have the source image and I want to create new images from the source.
What I have as input it is the rectangle areas that I want to extract. I suppose that I have to create blank images but I don't know how.

[EDIT]: I think the built in function
Quote: "integer CopyImage( fromImage, x, y, width, height ) "
does my job
