Date Posted: 11 Jan 24 at 4:58AM

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
