Writing a .jpg image

Is it possible to write a .jpg image in blitz? I know with saveimage you can save in .bmp but not .jpg, so how would I go about doing this?

SaveImage image,"image.jpg"

That should do the trick.

That'll save a BMP file with a JPG extension, won't it?

It wouldn't compress it, no. But it would create a jpeg image.
I'm not sure if there is any sure-fire way to create a true jpeg image.

I don't have Blitz3D installed any more so I can't prove it, but I'm quite sure you're wrong. The file will still be saved with a BMP header.

Yes, I think Gfk is right, it is a .bmp file with a .jpg extension. But maybe you could use FreeImage to save jpg ?

SaveImage saves to BMP only.

:/ Right, there is also a command called FreeImage .. which makes my remark quite ambigious.. Actually I ment this:

If you do


SaveImage image,"image.bmp"

and then do


SaveImage image,"image.jpg"

and open both files in notepad, you'll get the same exact text. (BMP encoded)
