try

dw.DrawImage(0, 0, img);

(You are drawing outside the area at 500, 500).

Or perhaps you really wanted

dw.DrawImage(0, 0, 500, 500, img)

- stretches the image to fill the area.

Anyway, that is still too ineffective, there is a nice function:

RichObject CreateImageObject(const Image& img, int cx = 0, int cy = 0);

which produces RichObject directly, without the need of ImageDraw.

Hello Guido,

I am facing your same problem, that to load a file image in a qtf document. It seems you have resolved this problem.
If you have still the correct test case may I ask you to post it?
Many thanks,
Luigi

No prob, I found the answer just in the reference:

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

GUI_APP_MAIN
{
	DrawingDraw dw(500, 500);
	Image img = StreamRaster::LoadFileAny("C:\\MyApps\\qtfimage\\ita.png");        
    dw.DrawImage(0, 0, 500, 500, img);	
	QtfRichObject pict(CreateDrawingObject(dw.GetResult(), Size(500, 500), Size(500, 500)));
	
	String qtf;
    qtf << pict; 
	PromptOK(qtf);
}

that is practically your initial code (it didn't work at my first experiment). But still I have not uderstood the Mirek's suggestion about the use of
RichObject CreateImageObject(const Image& img, int cx = 0, int cy = 0);
