Cropping a PDF

Aspose.PDF Product Family

Hi,

Is is possible to crop a PDF before it is converted to an image file type. I saw multiple ways to convert the PDF page directly, but my requirement is to crop the PDF to a general area on the page that has content, prior to making it an image.

Hello Oscar,

Thanks for using our products.<span style=“font-size:10.0pt;font-family:“Arial”,“sans-serif””>

I
am afraid currently Aspose.Pdf for .NET does not support the feature of converting certain region of page into image format. However for the sake of implementation, I have logged this requirement in our issue tracking system as PDFNEWNET-30267 under new features list. We will further investigate this
requirement in details and will keep you updated on the status of a correction.<span style=“font-size:10.0pt;font-family:“Arial”,“sans-serif””><span style=“font-size:10.0pt;
font-family:“Arial”,“sans-serif””>

We apologize for your inconvenience.
