Is there a way to split an image into several sprites like you do whith CreateAnimatedSprite()?

But I don't want an animated sprite :p. I just have an image from a card deck and want to split the images so that each card becomes a seperate image.

You can draw it to a bitmap, then use dbGetImage(); to grab each card
Let's say you have it 13 by 4.

+ Code Snippet

dbCreateBitmap(1,13*cardWidth,4*cardHeight);
dbSetCurrentBitmap(1);
dbLoadImage("cards.png",1);
dbPasteImage(1,0,0);
int xc,yc;
for(xc=0;xc<13;xc++){
    for(xy=0;xy<4;xy++){
        dbGetImage(imageNumber,xc*cardWidth,xy*cardHeight,xc*cardWidth+cardWidth,xy*cardHeight+cardHeight,1);
    imageNumber++;
    }
}

Or something to that effect. Unfortunately, there is no internal function (that I know of) to do that.

My site, for various stuff that I make.

Or, if you can maintain one image and use a sprite for the cards you need to display, use dbSetSpriteTextureCoord (int iSprite, int iVertex, float fU, float fV ).

You'd need to call the function four times to set the percentage of the four corners.
