问题 I try to write a validation method in a VB project to check if a PDF file is PDF/A. I was playing with itextsharp.pdfa but i don't find a way to validate this.

问题 I'm having troubles with this, I managed to set the size of the pdf document to the one I needed (~3cm x ~7cm), but the content inside the pdf is using like a third of the space. And I need to use the whole available space. So, this is how it looks: http://s9.postimg.org/hrxsjjagv/fill.png See how all the content is centered in that little space in the middle.
