MSVC Problem debugging pdfwrite

Peter,

The new devs.mak compiles both pdftext and pdxtext.
These 2 versions define different data structures for same type names,
pdf_font_descriptor_s is an example.
MSVC gets confused with it, so that the debugger shows
pdxtext data types instead pdftext data types,
and the debugging of pdftext isn't longer possible.

To work around I locally replaced

	$(DD)pdtext.dev : $(DEVS_MAK) $(ECHOGS_MAK) $(DD)pdftext.dev
$(DD)pdxtext.dev
		$(SETMOD) $(DD)pdtext -include $(DD)pdftext

with

	$(DD)pdtext.dev : $(DEVS_MAK) $(ECHOGS_MAK) $(DD)pdftext.dev
		$(SETMOD) $(DD)pdtext -include $(DD)pdftext

Can you change the logics of pdftext/pdxtext selection for fixing it ?
Thank you.

Igor.

GS CompatibilityLevel switch

Hello,

Setting the switch to 1.1 helps to solve some
conversion problems with epstopdf (as far as I
could test with 7.03, either bitmap eps or with some
Times-Roman fonts from xfig on screen display).

This switch seems undocumented, so the current solution
is to print a warning.
Could it be set in the tex2pdf script without reluctance
(in other terms, can it be harmful or even inefficient
for normal use ?).

Please reply personnaly, I'm not subscribed to the list.

Regards.

Mixing CMYK pages

If the file is DCS 2.0, then epstool will allow you to 
render each page to a greyscale bitmap, then combine them 
into a CMYK bitmap, then write it out as an EPS composite 
page.  If it is ordinary PostScript, then epstool won't do 
it.

There are some PostScript methods for rendering only some 
colours (Separation colour spaces)while leaving the others 
alone, which would allow you to render one colour at a 
time, but I don't know if this is supported by ghostscript.

Re: MSVC Problem debugging pdfwrite

Your fix is completely reasonable.  It is unfortunate that MSVC has the
limitation that it cannot compile multiple files with conflicting names even
if only a non-conflicting subset is actually linked into the executable.

I will change the comments in devs.mak so that it normally only compiles
whichever of pdftext or pdxtext is actually being linked.

Re: Mixing CMYK pages

Miguel and Russell,

Ghostscript does not yet support the /Overprint flag of Separation
color space. Once it does, then it will be fairly easy to merge
individual C, M, Y and K planes into a CMYK composite.

This feature is planned for 8.0 along with support for DeviceN
color spaces. We are nearing a commit to CVS with the DeviceN
merged code and will have a tester release within a few weeks.

The 8.0 release is expected by September (my best guess) but
could beat that date, or (hopefully not) be later.
