I want to export de printpreview to a pdf-file.
I have an lib to write on the canvas of a pdf-file.

But the resolution of the printpreview is a lot bigger as a pdf file.

Is there some way to scale the canvas or first export is to an image.....

heh.. i usually use wn2pdf ghostprinter, but if you have lib, then maybe it's some way restricted to low resolution? (i can print on it with really high resolution)

this is solution!

but I want to have everything in my own application.
now I have a resolution of 21000*29700 with tprintpreview.

when i write the canvas of tprintpreview on a canvas of a pdf-file I see nothing. If I'm lucky the topleft of the border.

does anybody have experience with this problem?

try to lower units (ex. from HiMetric to LoMetric).

How do you print the preview as PDF, using metafiles or direct print?

Via Metafiles..

PrintPreview's metafiles are in screen resolution, however if you stretch them on the target area, there should not be any problem.

expbmp := TBitMap.Create;
expbmp.Width:=2100;
expbmp.Height:=2970;

Windows.PlayEnhMetaFile( expbmp.Canvas.Handle,
PrintPreview1.Pages[ 1 ].Handle,
Rect( 100, 100, 2100, 2970 ) );


This works
