Converting a Bitmap to RTF code (Views: 102)

Problem/Question/Abstract:

How do I convert a Bitmap to RTF code?

Answer:

function BitmapToRTF(pict: TBitmap): string;
var
bi, bb, rtf: string;
bis, bbs: Cardinal;
achar: ShortString;
hexpict: string;
I: Integer;
begin
GetDIBSizes(pict.Handle, bis, bbs);
SetLength(bi, bis);
SetLength(bb, bbs);
GetDIB(pict.Handle, pict.Palette, PChar(bi)^, PChar(bb)^);
rtf := '{\rtf1 {\pict\dibitmap0 ';
SetLength(hexpict, (Length(bb) + Length(bi)) * 2);
I := 2;
for bis := 1 to Length(bi) do
begin
achar := IntToHex(Integer(bi[bis]), 2);
hexpict[I - 1] := achar[1];
hexpict[I] := achar[2];
Inc(I, 2);
end;
for bbs := 1 to Length(bb) do
begin
achar := IntToHex(Integer(bb[bbs]), 2);
hexpict[I - 1] := achar[1];
hexpict[I] := achar[2];
Inc(I, 2);
end;
rtf := rtf + hexpict + ' }}';
Result := rtf;
end;
