      Description

      I have lots of PDF documents with CID/Identity-H encoding which convert to images just fine on a Windows 7 platform, but the conversion on Linux causes garbled text in the image.

      I have permission from Blue Chyp Ltd to share a culprit PDF publicly in the PDFBox community - the first attachment.

      Running "java -jar pdfbox-app-2.0.5.jar PDFToImage BC600_S1_P3_A708__A.PDF" on Linux gives an image with garbled text - the second attachment.

      However, running the same command on Windows 7 gives a faithful jpeg image - the third attachment.

      I used the 64 bit JRE 8 update 131 In both the Windows and Linux environments.

      I used to suffer from lots of PDF->Image conversions giving garbled text at PDFBox1.8. Upgrading to PDFBox2.0 has fixed most of these issues, except for this odd one with identity-H encoding with the Linux JRE.
