= set_edge_mode =

== Syntax ==
{{int set_edge_mode(int mode)}}

== Arguments ==
:'''mode'''
::Set to '''0''' for a repeating edge, '''1''' for a black border around the image, '''2''' to wrap around the edges of the image to the other side, '''3''' to mirror the edges of the image.

== Return ==
False / zero if the mode value is out of range (less than 0 or greater than 4). True otherwise.

== Description ==
Sets how the plug-in should behave when accessing pixels beyond the edges of the image (ie whether the plug-in should show those pixels as black, mirror the edge, or wrap around to the other side of the image).

== Example ==
<code>
%ffp

ctl(0): "Edge Mode", Range=(0,3), val=0
ctl(1): "Image Offset", Range=(0,100), val=30

ForEveryTile:{

int r, g, b, offset;

set_edge_mode( ctl(0) );
  offset = ctl(1);

for (y= y_start; y < y_end; y++) {

if (updateProgress(y, y_end)) abort();

for (x = x_start; x < x_end; x++) {
				
      r = src(x-offset, y-offset, 0);
      g = src(x-offset, y-offset, 1);
      b = src(x-offset, y-offset, 2);

pset( x, y, 0, r );
      pset( x, y, 1, g );
      pset( x, y, 2, b );
    }
  }

return true;
}
