PrintImage(img)

CATCH

Message.Error("Classe: " & Str(Error.class) & "nCode: " & error.code &

", = " & error.text & "nà: " & error.where, "OK")


END

PRIVATE SUB PrintImage(fichierimg AS Image)


DIM imageToPrint AS Image

DIM imageWidth AS Integer

DIM imageHeight AS Integer

DIM scaleIsotropic AS Float


INC Application.Busy


imageWidth = (fichierimg.Width * Printer.Resolution) / Desktop.Resolution

imageHeight = (fichierimg.Height * Printer.Resolution) / Desktop.Resolution



IF imageWidth > Printer.Width OR imageHeight > Printer.Height THEN

scaleIsotropic = Min(Printer.Width / imageWidth, Printer.Height / imageHeight)

imageWidth *= scaleIsotropic

imageHeight *= scaleIsotropic


END IF



imageToPrint = fichierimg.Stretch(imageWidth, imageHeight, TRUE)




Draw.Begin(Printer)

Draw.Image(imageToPrint, (Printer.Width - imageWidth) / 2, (Printer.Height - imageHeight) / 2)

L'attente pour l'impression peut être longue (1 à 2 minutes) en fonction de votre matériel et de la taille de l'image.
