Subject: Re: How can I save contents of printer DC to Bitmap file

Hi Alex,

TPrinter has a Canvas property so you can transfer the canvas of Printer to the canvas of a TJpegGraphic. If I got the parameters right it should look like:

JpegGraphic := TJpegGraphic.Create.

JpegGraphic.NewImage(...);

JpegGraphic.Canvas.CopyRect( DestRect, Printer.Canvas, SourceRect);

Best regards,

Michel
