Printing AX-V7 in .NET using the PrintDocument???

Alex · Post by **Alex** » Mon Nov 29, 2004 12:29 pm

Hi all!

Is it possible to print Tcharts using the .net-printdocument, so I can use the .net print preview and all of the other document related stuff of VS?
I need to place more (>2) Tcharts and mixed graphics on a single page?

If yes, can somebody post me a short coding example for VB?

Thanks in advance!

Alex

Hi Alex,

yes, this can be done. The best way is by exporting the Chart image to stream, and then when you need to print it, import the stream as an image and draw it on the Print Document, using the DrawImage method in the PrintPage event.

Hi Pep,

thanks for the hint. I came to a similar solution to print on multiple pages using this method.
If someone looks for the code I use:

Code: Select all

                Dim TStream As New System.IO.MemoryStream
                FGrafik.TChart1.Export.Image.Metafile.Save(TStream)
                TStream.Position = 0
                Dim be_test As New Imaging.Metafile(TStream)
                e.Graphics.DrawImage(be_test, 25, 40, 250, 350)
                be_test.Dispose()

But what I still want to know: I use a metafile format, this is according to the definition a real vector format. E.g. I draw in TChart a polygon (x/y), why do the lines are splitted up in x/y resultion? Instead of my 10 point polygon I get a 40 point polygon based on the resultion of the metafile. Why are the lines not a single line between my polgon points? Is the basis of a metafile still "pixel"?

Thanks another time!

Regards

Alex

How can I see what you refer ? Could you please show me the code you're using to reproduce this behaviour ?

Hi Pep,

yes, of course. I think it's the best that I post two small pictures where you can see my problem. How can I send you these pictures?

Best regards

Hi Support!

Some comments to the pictures? Should I start a new thread?

Hi Narcis,

thanks for the posting. This problem was still solved according Pep's hint (the same way like your posting).

Concerning the EMF quality I will start a new thread.

Regards

Alex
