:{{int bTriangle(int x, int y, int centerx, int centery, int radius)}}
== Arguments ==
:'''x, y'''
::Current x and y coordinates in the image
:'''centerx, centery'''
::Center coordinates of the triangle
:'''radius'''
::Radius of the triangle
== Return ==
:If the supplied x and y values lie within the defined triangle a value of 1 will be returned, otherwise 0.
== Description ==
:Lets you easily draw a triangle on the image.
== Example ==
<code>
%ffp

ctl(0): "X",range=(0,255),val=150
ctl(1): "Y",range=(0,255),val=100	
ctl(2): "Radius",range=(0,128),val=64

ForEveryTile:
{

int Draw;

for (y=y_start; y<y_end; y++){
		updateProgress(y,y_end);
	for (x=x_start; x<x_end; x++){

Draw= bTriangle (x,y,ctl(0),ctl(1),ctl(2));

for (z=0; z<Z; z++){

if (Draw) pset(x,y,z,255);

}}}

return true;
}
