# CopyPixel src_x,src_y,src_buffer,dest_x,dest_y,[dest_buffer]

# Parameters

src_x - x-coordinate of source pixel to copy from src_y - y-coordinate of source pixel to copy from src_buffer - name of buffer to copy from, e.g. ImageBuffer() dest_x - x-coordinate of destination pixel to copy to dest_y - y-coordinate of destination pixel to copy to dest_buffer (optional) - name of buffer to copy to, e.g. BackBuffer()

# Description

You can use this command on a locked buffer for a slight speed-up. See LockBuffer. See also: CopyPixelFast.

# Example

; CopyPixel/CopyPixelFast Example ; ------------------------------- Graphics 640,480,16 Print "Press a key to use CopyPixel to copy the top half of an image to the frontbuffer" WaitKey() ; Load an image - can be anything pic=LoadImage("media/blitz_pic.bmp") ; Use CopyPixel to copy the top half of the image to the frontbuffer For y=0 To ImageHeight(pic)/2 For x=0 To ImageWidth(pic) CopyPixel x,y,ImageBuffer(pic),x,y Next Next Locate 0,GraphicsHeight()/2 Print "Press a key to use CopyPixelFast to copy the bottom half of the image" Print "Once this has finished, you can then press a key to end the program" WaitKey() ; Lock buffer before using CopyPixelFast LockBuffer ; Use CopyPixelFast to copy the bottom half of the image to the frontbuffer For y=0 To (ImageHeight(pic)/2)+ImageHeight(pic) For x=0 To ImageWidth(pic) CopyPixelFast x,y,ImageBuffer(pic),x,y Next Next ; Unlock buffer after using CopyPixelFast UnlockBuffer WaitKey()
