Hello pdfuserxx,

The EMF to PDF conversion code in Quick PDF Library is quite complex as there are many differences in the graphics APIs of GDI and the PDF side of things.

In general, only a subset of the GDI API is available. GDI+ is not supported.

It's sometimes difficult to make changes to the code as we don't want to negatively affect existing software using this functionality.

However the QPL team might be able to support changes to support transformations in a future version of QPL. Please post a few example commands that you use and we will run some tests to analyse the EMF commands and work out the corresponding PDF commands.

Regards,
Kevin

Are there anyknown limitations when using using GDI/GDI+ to draw on pdf canvas obtained by calling GetCanvasDC.

 

I’m using GDI to generate PDF document, the code is as follows:

 

pdfLibrary.GetCanvasDC(..

 

..Paint on the canvas with GDI

 

 pdfLibrary.NewPageFromCanvasDC

 

int capturedPage = pdfLibrary.CapturePageEx(..produce vector graphics

 

pdfLibrary.SelectPage(currentPage + 1);

 

pdfLibrary.DrawCapturedPage(capturedPage,...

 

This works fine when allthe elements have rotation 0 or. no transformations applied, but the output will beincorrect when elements are rotated or. GDI transformation is applied.
