Hi Bingdao,

i don't have a sample for this issue but i know that the functionalities from QuickPDF can help you doing the described job.
If you don't find here a relevant sample you have to do it by your own.


I've searched a bit on the QuickPDF-pages for you and found these two threads for example:

Perhaps you'll get an idea how to do it from this thread (but it's the other way round A4->A3):

Here's another thread about changing the pagesize:

I want to save a PDF file of A3 as a PDF file of A4, and the content is also reduced in proportion.

What can Debenu Quick PDF Library do?

Hi Bingdao,

if you want to scale content to fit into different dimensions you won't find a ready made solution inside QuickPDF.

Here's a sample code from AndrewC (ex Debenu member, R.I.P.) how to do it with QuickPDF:

Outside QuickPDF here's an article regarding your question:

Additionally you should have a look into the samples-section here.

Still problems?
