Although I teach introdutory programming, I'm new to DarkBASIC. I'm confused on the parameters for the COPY BITMAP 10 parameter command. What parts of the bitmap does Left, Top, Right, Bottom correlate to? I know it's X/Y coordinates, but an example I was looking at in Jonathan Harbour's book was confusing (the example he used was: Copy Bitmap 1,2,5,6,7,0,2,5,6,7).

Can some give me a detailed explanation?

Thanks!

The example that you have quoted is a bit odd. It is from bitmat 1 to bitmap 0 using tiny little pixels.


Copy Bitmap....From Bitmap,Left,Top,Right,Bottom,TO BITMAP,left,top,right,bottom

Doesn't really need any explaining.... it's

X,Y top to X,Y bottom

I know it's odd, but that was the example in Jonathan Harbour's book. In the example, the bitmap he was copying from was an 8x8 grid with a smilie. The resulting bitmap was a portion of the smile without the eyes.

I understand it now. You just make a "box" from the 2, 5 and the 6,7 coordinates and that's what's copied over. Makes perfect sense, but it wasn't explained in the book.

Thanks!
