RenderPageToGdPictureImageEx

[ldm]

Hi,
I have a problem using RenderPageToGdPictureImageEx method.

I have a PDF in a GdPicturePDF object.
Dimensions of the PDF file read from Acrobat Reader are 220 x 309 mm.

My code:

Code: Select all

_oGdPicturePDF.GetPageHeight() returns 876
_oGdPicturePDF.GetPageWidth() returns 624
int _RasterPageID = _oGdPicturePDF.RenderPageToGdPictureImageEx(200, true);

_oGdPictureImaging.GetVerticalResolution(_RasterPageID) returns 72
_oGdPictureImaging.GetHorizonatlResolution(_RasterPageID) returns 72

Shouldn't it be 200 ?

This causes many problems using DrawRotatedText method...

Thank you all !

Hi,

Shouldn't it be 200 ?

Yes and no

Yes: If the page is raster based and embed a 200 DPI bitmap, or if the page is not raster based and required rasterization to be converted to bitmap.

No: If the page is raster based and embed a non 200 DPI image (this is your case).

Let me know if I am not clear enough.

With best regards,

Loïc
