Hi Bernhard,

The Canvas property of the TDibGraphic class may be used to
print text (or draw lines, rectangles, etc...) on an image.
See Delphi's online help on TCanvas for the available methods.

For example, the evaluation version uses this to display the
name of the library in the upper left corner:

Graphic.Canvas.Font.Size := 10;
Graphic.Canvas.Font.Name := 'Arial';
Graphic.Canvas.Font.Style := [fsBold];
Graphic.Canvas.Font.Color := clLime;
SetBkMode(Graphic.Canvas.Handle, Windows.TRANSPARENT);

Graphic.Canvas.TextOut(4, 2, 'Envision Image Library Demo');

Graphic.Canvas.Font.Color := clGray;
Graphic.Canvas.Font.Size := 9;
Graphic.Canvas.TextOut(4, 20, 'www.intervalsoftware.com');

SetBkMode(Graphic.Canvas.Handle, Windows.OPAQUE);

Graphic is a reference to a TDibGraphic class which may be
contained for example in the TImage.Picture.Graphic property, or the TImageScrollBox.Graphic property.

When using the TImageScrollBox component, make sure the
Redraw method is called after writing on the Canvas of the
Graphic.Canvas property.

Best regards,

Michel
