Thank your for your interest in our products.

There is no such sample available at the moment, sorry.

In general, you should perform the following steps to set the background:
1) Set TElPDFSignature.WidgetProps.BackgroundStyle to pbsCustom,
2) Assign the array containing binary representation of a JPEG2000 image to the TElPDFSignature.WidgetProps.Background.Data property,
3) Set Width and Height properties of the TElPDFSignature.WidgetProps.Background object according to the parameters of your JPEG2000 image.

Thank You. My code is this.

ImageF : File;
Buf : ByteArray;
camino : string;

Sig.WidgetProps.BackgroundStyle := pbsCustom;

Sig.WidgetProps.Background.Height := 172;
Sig.WidgetProps.Background.Width := 177;
Camino := 'c:\Tca\IMFACEL.JP2';
AssignFile(ImageF, camino);
system.Reset(ImageF, 1);
SetLength(Buf, FileSize(ImageF));
system.BlockRead(ImageF, Buf[0], Length(Buf));

Sig.WidgetProps.Background.ImageType := pitJPEG2000;
Sig.WidgetProps.Background.Data := Buf;

But the image does not appear in the pdf.
