[bug-pcl] Problems when converting PCL to PDF

[Yuan Liu]

Hello,

First of all, I really appreciate the work that is done for ghostpcl, it
works much better than most commercial pcl processing software. 

I am currently trying to convert some of the pcl images outputted by our
program into pdf by using the pdfwrite device. It seems I keep hitting the
same or similar problems when trying to convert a colour pcl into a pdf. It
all seems related to wrong number of arguments for the 'setcolor' command in
pdf (at least that is what I see when I open the pdf in Adobe). I have
attached some examples with this email (colour-line.pcl, colour-line.pdf,
in1.pcl and out1.pdf).

There is also a problem when converting pcl that contains text underline.
The underline disappears when converted to pdf. See attachment underline.pcl
and underline.pdf.  

If this is a bug, is there already a fix out there? If not can anyone point
me to the relevant section of the source code? If it is not a bug can anyone
tell me what the problem is please. Any help will be greatly appreciated.
