Page Orientation vs. page dimensions.

There seems to be an orientation problem, we're trying to normalize a pdfs to a consistent page orientation. I am working with my developer to clarify but the gist is that he can pull in the orientation (iterating through a multi-page pdf) but that value is inconsistent - doesn't always jive with the page dimensions so that was why he went to look at page size and dimensions where "width being greater than height equals landscape" but apparently that is also inconsistent as page height is zero at times. He's using the pdf library from SyncFusion but we're not sure if we are running into malformed pdfs or we are not using the API properly. I can't share pdfs as they are sensitive and I don't have access to his code but I might be able to get that. I know that doesn't make it easy to figure this out an I apologize for that. Thanks, Bob

Bob isn't the only one facing this issue. Why was this handled in private?

Hi Cheech, 
Thank you for contacting Syncfusion support. 
We can get the page size from the existing document by using the property called Size available in the class PDFLoadedPage. Currently, Syncfusion does not have the property to get the PDF orientation, but you can work around this by comparing the actual page width and height. 
Refer to the below sample to get the page size and its orientation. 
If still you are facing an issue, kindly provide more details such as modified sample, input document, product version to check the issue in our end. So, that it will be helpful for us to analyze and assist you further on this.
