Overlay Merge

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have 2 pdf files, each pdf file contains 1 page. I need to overlay one of these files on top of of the other and create a new pdf file with a single page. 

I have tried using the MergeFiles function, but this creates 2 pages in the new pdf file, 1 after the other, this is no good as i need both the pdf files on the same page.

Is there any way i can achieve this? if so, could you tell me which functions i need to use.

Many thanks for your help

Paul

	Hi Paul, at the moment I am using most of the time for rendering so maybe I have an impropper answer for you. After a first look on your problem it seems that you have to iterate over all objects of one document page and add them to the other. I hope that this helps. Regards, Marian

	Hi Paul, after merging the two files, which is neccessary, you can do this: LoadDocumentFromFile CapturePage(2) SelectPage(1) DrawCapturedPage(...) That places the second page onto the first. Edited by JanN - 30 Nov 06 at 5:01PM

	Hi Jan, Many thanks for your help, thats exactly what i needed. The only problem i had was using the drawcapturedpage function, i was putting 0, 0 for the left and top co-ordinates, this caused the second page to not appear. After some trial and error, i found out that the top co-ordinate needs to be the page height, so now it works, i get both pages merged together on a single page. Thanks again Paul

	You're welcome. A small hint: SetOrigin and SetMeasurementUnits make things a little bit easier.
