Hello,
I am currently trying to implement a functionality that allows adding letter paper to an already existing PDF.
Technically this means that I want to select a picture of some kind and assign it as background to every page of the existing PDF.
I've had some difficulties achieving this with other PDF-components, such as all the layers being turned into one image thereby causing the PDF size to explode, which is why I would like to attempt this with Imageen but after experimenting around a bit I am not exactly sure how I should properly do this. Would I do some kind of canvas drawing with transparency or utilize layers maybe, or the PDFBuilder even though the PDF already exists?
I didn't find my exact problem in this forum or the demos, which is why I would be thankful if you could give me hint as to how this should be properly done with Imageen, or maybe I've overlooked something, which you could point me to. |

Hi
So the method to do with with ImageEn would be to use a PDFViewer (hidden or visible) to load the page, add an image to it and save the page.
Please see the demo:
\Demos\PDF\PDFPageObjects\PDFPageObjects.dpr
PDF Page Objects Demo EXE
But:
- PDFium does not provide a method to change the z-order of objects (and you would need the image to be behind all the other objects). Email us for a workaround method to do this
- Adding an image to every page of a PDF is definitely going to make it much larger
