Hi Maruan, I have successfully converted pdf to images using pdfbox. However there are couple of attached pdf which does not shows up filled in details.
In my use case i need to merge different pdf's and than convert to series of images. Since these pdf are not converted to image properly i would like to avoid merge or fix image generation. Can you please point me to right direction. Converting this pdf with imagemagick works fine but i would like to avoid os level tool. Really appreciate your help Thanks -Ankur Tripathi On Thu, Jun 6, 2013 at 4:01 PM, Maruan Sahyoun <[email protected]>wrote: > Hi, > > the question if a PDF can be rendered successfully is not dependent on the > fact that it's a PDF/A file.
