= t3get =
== Syntax ==
:{{int t3get(int x, int y, int z)}}
== Arguments ==
:'''x'''
::The x coordinate of the pixel to be retrieved.
:'''y'''
::The y coordinate of the pixel to be retrieved.
:'''z'''
::The channel number to be retrieved for the pixel: 0->red, 1->green, 2->blue, 3->alpha.
== Return ==
:The integer value of the specified pixel for the specified channel.
== Description ==
:This function retrieves the value of a specified channel 'z' from the pixel at position (x,y) in the third of FilterMeister's tile buffers. The coordinates should usually be within the image, ie 0<=x<=X and 0<=y<=Y, while the channel number z should be in the range 0 to 3 inclusive. Channels 0, 1 and 2 are the red, green and blue channels respectively, while channel 3 is the alpha (transparency) channel and is valid only on a layer.
== Example ==
<code>
// Copy tile buffer 3 to the output buffer

for (y=y_start; y<Y; ++y) {
    for (x=x_start; x<X; ++x) {
        for (z=0; z<Z; ++z) {
            pset(x, y, z, t3get(x, y, z));
        }
    }
}
