Description
This function searches for a given color specified by Color inside of a given triangular search area specified by three coordinates which represent the corner points (X1, Y1), (X2, Y2) and (X3, Y3) using a scan-line pattern.
The function returns false if the color was not found, if it was it returns true and the coordinates of the found color in (X, Y). The search will stop after the first instance of the color was found.
Example
var
x, y: Integer;
begin
if FindColorTriangle(x, y, 0, 100, 0, 0, 100, 200, 100) then
WriteLn('Found color at ' + IntToStr(x) + ', ' + IntToStr(y));
end.
