Good program. Possibly you should include a color to gray scale algorithm. It is
very simple and guarantees that the conversion of colored pics is identically
with the perception of human eye.

Delphi-Code:

:function Color2Gray(AColor:TColor):TColor;
:var
:  immi : LongInt;
:begin
:  immi:=(((AColor         and $FF)*77 +
:         ((AColor shr  8) and $FF)*151 +
:         ((AColor shr 16) and $FF)*28 ) shr 8) and $FF;
:  Result:=RGB(immi,immi,immi);
:end;

(ca.: 30% red, 11% blue, 59% green)
