I'm calling PDFBox to Extract text from a PDF file, within a PHP script. The extracted text is output to the 'console' which I then read in PHP as the 'stdout' from the program. Errors I read from a similarly piped 'stderr'. > > Now unfortunately getting the return code from executing external programs in PHP is very flaky and so I cannot use an exit code of 0 from PDFBox to determine success or failure. The only way I can check whether everything was ok is to check the contents of stderr. > > However because of all these INFO messages, stderr may not be null even though everything is ok (I understand it is safe to ignore these particular INFO messages). I am forced to having to parse the stderr and use a regex to delete these info messages and see if there is then anything left which might mean error. This is not very good practice :( > > So, is there a way I can stop these INFO messages being produced in stderr?

The "Proposed Insured" pdf fields (pdf field name: InsuredFullName) at the top of page 3 & 4 displays correctly, but the same field at the top of page 5 does not. I do see the expected image if I use Adobe Reader which is why I am turning to you. I display the image on a JPanel using the PDPage.convertToImage() method, but PDFToImage displays the same output. I have attached the pdf. I am happy to attach images separately; they won't fit under 1MB.
