Copy a region out of a Pixmap

BlitzMax Forums/BlitzMax Beginners Area/Copy a region out of a Pixmap

Hello!

Another newb question from me:

If a pixmap I have loaded up is wider than 340 pixels
I want the pixmap being replaced by the first 0-340 pixels.
So the new pixmap is only 340 in width of the original larger image. No resizing. Just simple "copy" out.

tmppixmap=LoadPixmap("MyLargeImage.jpg")
If tmppixmap.width > 340 Then
tmppixmap=tmppixmap.copy ...????
endif

How can I do this?

Thanks, Grisu

manually copy pixels thought the pixel commands would be the way to go. (and it would be 0 - 339 if it has a width of 340)

But isn't read/writepixel aweful slow?

Isn't there something like CopyImagRect in bmx?

Drawimage rect which can be saved as pixmap

You'd need to check the size being copied is smaller than the actual image w/h...
Function tg_copyimagerect:TImage(image:TImage,x1:Int,y1:Int,x2:Int,y2:Int)
    Return LoadImage(PixmapWindow(LockImage(image),x1,y1,x2,y2))
End Function


Thanks, have it now:
tmppixmap=PixmapWindow(tmppixmap,0,0,340,340)

Nothing is faster than that... :)
