// This example add a mask to a monochrome image

// =============================================

ImgScale(MaskImage, ImgGetWidth(_CurrentImage), ImgGetHeight(_CurrentImage), false);

// If template black color is not "1" then the mask is inverted

if ImgGetBlackValue(MaskImage)=0 then ImgInvert(MaskImage);

// If image black color is not "1" then the image is inverted

ImageInverted:=False;

if ImgGetBlackValue(_CurrentImage)=0 then

begin

 ImgInvert(_CurrentImage);

 ImageInverted:=True;

end;

// Add on current image the mask using logical "OR" operation

ImgAddOr(_CurrentImage, MaskImage);

// Delete the mask

ImgDelete(MaskImage);

// Re-invert the image is previously inverted
