Understanding Size in PDFProcessing

[Chris]

Real beginner question here but need some pointers on sizing in a PDF document. 

Can anyone explain sizing in PdfProcessing?

First question - How is the page size defined for RadFixedDocument, does is default to A4 or is there some kind of measurement setting applied by default?  Does this same metric apply to the rest of the document (e.g. is it all mm/pixels or some other measurement)

RadFixedDocument document = new RadFixedDocument();

Second question

How is image size in pixels relative to the sizing on the page itself.  In the sample below, imageSource.Width is pixels taken from the actual image, how does that translate to a relative size on the page?

 

[Chris]

Code for the second question (sorry the code editor lost the OK button)

using (Stream companyLogoImage = ContentGenerator.GetCompanyLogo())
 {
     var imageSource = new Telerik.Windows.Documents.Fixed.Model.Resources.ImageSource(companyLogoImage);
     editor.InsertImageInline(imageSource,new Size(imageSource.Width, imageSource.Height));
 }

 

Any pointers appreciated, thanks.

Ah just come across Telerik.Windows.Documents.Media.Unit for converting measurements to DIP (Device Independent Pixels).

Which answers the sizing questions - the following will specify A4 sizing:

new Size(Telerik.Windows.Documents.Media.Unit.MmToDip(210), Telerik.Windows.Documents.Media.Unit.MmToDip(297));

Hello Chris,

Thank you for the feedback.

Indeed, the measurement unit in the PdfProcessing library is DIP (Device-independent pixel). We have an internal item to provide detailed information about the PdfProcessing measurement unit and about this helper class, so I am including your feedback on it.

If you need any further assistance, please, let us know.

Hello Martin,

Is the "detailed information about the PdfProcessing measurement unit" available yet?

Hello Gerhard,

I am afraid the article is still not updated but you can find information about the Unit class in our API Reference documentation -

Class Unit.

If you have any specific questions I would be happy to help you with them.
