RenderPageToString() resolution issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I opened a pdf document with the following sizes: 3.37 X 2.12  I call a library method that creates bitmap, asking for 300 dpi resolution: RenderPageToString(300, 1, 0) 
I am expecting to get a bitmap, having 1011 x 636 pixels.
(3.37x300=1011   2.12x300=636)

But the bitmap I get is 809 X 510.

Why do I get this resolution? Is this a library bug?

	Hi Kathy :) Perhaps a look into chapter "Measurement and coordinate units" from the referenceguide will help? Have a special look on the functions below. Calling them first could change your result... SetMeasurementUnits SetGlobalMeasurementUnits SetGlobalScale
	Cheers, Ingo
