Hi,

I need to print some external pdf-files (single page) in a Report.
As I don't know the orientation, I cannot choose landscape/portrait mode.

Is there a way to check the pdf-file on it's orientation?

thanks

Erik

Hi,

if you want to use native WLanguage function you can use the following function to get an image variable and use the variable to get size of a page of your PDF (it is a little dirty solution for the problem)

You can also use a .NET dll to do something like the following example

Hi Erik,

there seems to be no PDF document's property telling you that. However, you could use the PDFExtractPage(..) in order to extract the/a page of the document and judge upon its width and height (ImageHeight(..) and ImageWidth(..)) whether the extracted page is in landscape or partrait format.

A warning however. Printing a multipage document using iPrint-functions and changing landscape / portrait may end up in a bad printout because portrait-margins are kept in ladscape! So currently, mixing of landscape / portrait printing within a single document is not recommended. PC Soft knows about that bug but it's not fixed yet.

Hi Guenter and HIS,

that's exactly what I need. Unfortunately this function is available from WD20 and I have not yet moved (never touch a running System!). Just new Projects are using WX20.

So I have to wait until it's time to Change.

thanks a lot

Erik
