Image Processing?

Hi
I'd like to write a format for sprites that stores more informations about frames, blending, animations. For that I'd like to know more about how can I read the pixels from a image and how should I write pixels to a TImage for when I load it.
My application is going pretty well but that info is vital

EDIT:
Also is it possible to have pixmaps of different sizes in a TImage?
If not I guess you I can use multiple Images but I think that's a slowdown.

lockimage, readpixel, unlockimage

lockimage,writepixel, unlockimage

I've either misunderstood or you might need to check what a pixmap is again.

It would be much more efficient for you to read and write pixmaps and then convert the pixmap into/from an image, rather than use pixel reading and writing.

your best bet is to store your images all in one texture or maybe a couple. that way you can have different sizes and all kinds of other things packed in there. I was headed down that path myself until I got bored :(

do a search in this forum on "single surface".

I thought that you could only write pixels to a pixmap. I tried writing pixels to an image without success. Do you have some code to show this in action?

That is true and is why you need to lockimage to obtain access to the pixmap. This is then reflected the next time the image is drawn.

OK. I know where I went wrong now. Cheers :)
