            Description

            The issue depends on which OCR tool is used, most notably PixEdit: http://www.pixedit.com/ocr.aspx. The attached test file "10279_Regular.pdf" has been used to create "10279_OCR.pdf" using PixEdit. When viewing the OCR version, the following exception is thrown by ICEpdf:

              This is related to a malformed content stream.

              Q0 0 0 rg

              For some reason the encoder is properly inserting a space between the Q and 0. PDF-215 describes a similar problem from another encoder. Good news is that there is a fix for it and is available in the 4.2.2 preview 1 release.
