#3574 — pdf definition

	Anyone know where to find a technical definition of PDF? I need to convert 
a text file to ps and then to pdf. Text to ps is simple and complete. The ps 
to PDF format is the current trouble. Or maybe text to PDF directly. There is 
no need for compression, so, if that can be omitted it would good. 
   Any suggestions would be appreciated.

The PDF Reference Manual is the techincal definition of PDF. Its now an 
ISO specification which costs (IIRC) 250 CHF, however the 1.7 version 
was published fro free by Adobe and is still available from their web 
site. You'll have to Google for it, they move it around frequently.

Unless you need the absolute newset features (which seems unlikely) the 
free version is quite adequate from a technical perspective, easier to 
read and more useful (for example it has an index, which the ISO 
specification lacks)

Use Ghostscript ?

Thanks Ken. The 1.7 version should be plenty. The hope is to make the
text to pdf code as small as possible; Ghostscript's not a giant but close.

This will do txt2pdf using ghostscript as explained in gslp.ps:

    gs -q -sDEVICE=pdfwrite -sPAPERSIZE=letter --permit-file-read="$1" -dNOPAUSE -sOutputFile=$1.pdf -sPROGNAME=$0 -- gslp.ps --heading-center "`date`" "$1"

I use these to avoid compression just not sure if this works for pdfwrite or just ps2write:

    -dCompressPages=false -dCompressStreams=false

Ghostscript will work if you can accept the speed.

If you know Java then Apache PDFBox at https://pdfbox.apache.org/ will 
produce PDFs much faster.

Thanks for the suggestions. The Java version might be ok for a 
translation to c.
