SCAR has some FindBitmaps functions but it only finds multiple instances of the same bitmap.
SCAR Code:
function FindBitmaps(Bitmap: Integer; var Points: TPointArray; xs, ys, xe, ye: Integer): Boolean;
Returns the coordinates of all instances of the entered Bitmap found in the search area in the Points array.
function FindBitmapsTolerance(Bitmap: Integer; var Points: TPointArray; xs, ys, xe, ye, Tol: Integer): Boolean;
Returns the coordinates of all instances of the entered Bitmap found with tolerance in the search area in the Points array.
function FindTransparentBitmaps(Bitmap: Integer; var Points: TPointArray; TranspCol, xs, ys, xe, ye, Tol: Integer): Boolean;
Returns the coordinates of all instances of the entered Bitmap found in the search area in the Points array. Pixels on the search Bitmap with the color defined by TranspCol will be skipped in the search.
function FindTransparentBitmapsTolerance(Bitmap: Integer; var Points: TPointArray; TranspCol, xs, ys, xe, ye, Tol: Integer): Boolean;
Returns the coordinates of all instances of the entered Bitmap found with tolerance in the search area in the Points array. Pixels on the search Bitmap with the color defined by TranspCol will be skipped in the search.
function CountBitmap(Bitmap: Integer; xs, ys, xe, ye: Integer): Integer;
Counts the number of instances of the entered Bitmap found in the search area.
function CountBitmapTolerance(Bitmap: Integer; xs, ys, xe, ye, Tol: Integer): Integer;
Counts the number of instances of the entered Bitmap found with tolerance in the search area.
function CountTransparentBitmap(Bitmap: Integer; TranspCol, xs, ys, xe, ye: Integer): Integer;
Counts the number of instances of the entered Bitmap found in the search area. Pixels on the search Bitmap with the color defined by TranspCol will be skipped in the search.
function CountTransparentBitmapTolerance(Bitmap: Integer; TranspCol, xs, ys, xe, ye, Tol: Integer): Integer;
Counts the number of instances of the entered Bitmap found with tolerance in the search area. Pixels on the search Bitmap with the color defined by TranspCol will be skipped in the search.
