Parameters |
Description |
|
const SrcImage: TAgkImage |
the image to use as a source. |
|
const SrcChannel: TAgkColorChannel |
the channel in the source image to use as the mask. |
|
const DstChannel: TAgkColorChannel |
the channel in this image to copy the mask to. |
|
const X: Integer = 0 |
(optional) The X offset for the source image on this image. |
|
const Y: Integer = 0 |
(optional) The Y offset for the source image on this image. |
This is a slow command and should not be called every frame. The X,Y offset values allow you to offset the source image on te destination image so a small source image can be used to mask any part of a large image. Any part of the large image outside the size of the small image will be left unchanged. Negative offset values are supported to shift the source image off the top left of the destination image.
