Description Marcos H. Woehrmann 2011-10-18 14:44:14 UTC
The customer reports:

The "overlay" that marks the document as a test one, overlaps parts of text. 
Here is the testcase and the tiff output with ghostpdl 9.04 (attached).

I'm traveling and don't have access to an HP printer so haven't had a chance to compare our output to theirs, but I'm checking now to see if master and earlier versions of GhostPCL generate different output.
Comment 3 Marcos H. Woehrmann 2011-10-18 15:02:30 UTC
Other versions of GhostPCL I tried, including 8.71, 9.04, and master all generate the same output, so it's not a regression.

What is the urgency of this issue?  We are working on redesigning color spaces in PCL and the problem file works properly in the development code.  Unfortunately it is will be necessary to take a complete release to integrate the new code - we can't provide a patch it is too large.  The release will be available in February.  Let me know if this meets your schedule requirements Horiana.  Thanks.

Hello,

Our customer is asking if there is a possible workaround for this problem. Maybe the stream can be changed somehow to avoid this problem. 
We've planned to start upgrading to GhostPCL 9.04 this month. In February, when you'll release the new code, will you prepare a patch for this issue or we will have to upgrade again to whatever version will be in that moment? 

Thanks.

The fix for this problem in 9.05 (February) cannot be fitted to previous release.  If the customer needs the fix before February or you can't upgrade to 9.05 then the problem will have to be fixed in the current code as a separate task.  Let me know.
Comment 7 Henry Stiles 2011-11-07 18:02:09 UTC
Horiana, I am losing confidence in the February deadline so I have fixed this in the current code, and it should be fairly easy to patch your code given the commit diff here:

Thanks, Henry

Hi,

We were about to start upgrading to GhostPCL 9.04 version. But then you mentioned that it will be a new release in Feb 2012. Therefore we decided to wait a bit for the new version. Could you advice us if we should move on with 9.04 or to wait for 9.05? If it won't be released in February then when it will be release? 

Thank you.

There will be a 9.05 in February, we release the code every 6 months (Feb, Aug) but the feature that fixes this particular problem may not be in by February.  So we've provided a workaround in the current code base.  It looks like the planned improvements scheduled for February will slip to Aug 2012 (9.07) so I don't think it really makes much difference if you choose 9.04 or 9.05, we haven't had significant improvements in PCL since 9.04.
