Change the background colour on shapes


#1

Is it possible to go through all Elements in the PDF and change the background colour to transparent on every element (rectangle, shapes,…) where the background colour is white?

I add two files, in the second file I changed the Background colour of some elements to transparent in in the upper part of the document. That is what I would like to do programmatically.

Thank you for contacting support.

Would you please elaborate how did you change the background color to transparent so that we may investigate further.

I have done this with the PDF XChange Editor (Demo Version)
In the Editor, I changed the Fill colour from “RGB white” to “None”

We are afraid this might not be possible with Aspose.PDF for .NET API at the moment. However, we have logged a ticket with ID PDFNET-47230 in our issue management system for further investigation and resolution. We will let you know once any update will be available in this regard.
