Description
This function searches for a given color specified by Color using a scan-line pattern. The search area is given as a set of upper-left (XS, YS) and lower-right (XE, YE) coordinates which are specified relative to the selected client window. If the given search area is invalid (XS > XE or YS > YE), an exception is thrown.
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
W, H: Integer;
X, Y: Integer;
begin
GetBoxSize(GetClient.ImageArea, W, H);
if FindColor(X, Y, 0, 0, 0, W - 1, H - 1) then
WriteLn('Found color at ' + IntToStr(X) + ', ' + IntToStr(Y));
end.
