function SimilarBitmaps(const Bmp1, Bmp2, Tol: Integer): Boolean;

Description

This function returns true if all pixels of 2 given bitmaps specified by Bmp1 and Bmp2 are within the tolerance range of each other specified by Tol. This is determined using the active tolerance algorithm which can be changed with ColorToleranceSpeed. An extended function with additional functionality is available as SimilarBitmapsEx.

Example

var
  b1, b2: Integer;

begin
  b1 := BitmapFromString(100, 100, '');
  b2 := BitmapFromString(100, 100, '');
  WriteLn(SimilarBitmaps(b1, b2, 5));
  FastSetPixel(b1, 5, 5, 255);
  WriteLn(SimilarBitmaps(b1, b2, 5));
end.

Output:

1
0
