Re: [Podofo-users] Conversion Cals to Pdf not working anymore sinceswitch from 0.5.0 to svn trunk!

[Dominik S. <dom...@we...>]

Hello Sebastian,

I am sorry, I did indeed mix up PdfPainter:DrawImage and 
PdfPainter::DrawXObject! 

You are absolutely right: for DrawXObject you have to pass 
PdfXObject::GetPageSize().GetWidth() and  
PdfXObject::GetPageSize().GetHeight() as parameters for dScaleX and dScaleY. 
You could also use PdfPainter::DrawImage to draw your XObject (as PdfImage is 
a PdfXObject) and this is the case where PoDoFo will pick these default 
values.

Sorry,
	Dom
