reproducer file

Hello guys,

we have noted a problem with Ghotstscript's Fontmap.GS file (from Resource/Init/ folder).

This problem probably occurs only when the Fonts are not located in default font path (/usr/share/ghostscript/Resource/Font), and they are located in other system folder (/usr/share/fonts/urw-bas35/ in Fedora).

Here's the reproducer:

> NOTE: Important parts are highlighted like this.

I have noted that the problem is (most likely) in Resource/Init/Fontmap.GS file. There's remap of Helvetica-Narrow-Bold-Oblique to NimbusSansNarrow-BdOblique:

-----------
% Aliases

<skipped>
> /Helvetica-Narrow-BoldOblique	/NimbusSansNarrow-BdOblique        ;

-----------

However, if you look at the contents of NimbusSansNarrowBdOblique, it contains:

> /FontName /NimbusSansNarrow-BoldOblique def

===========

So, to conclude - the filename does not correspond to /FontName inside the T1 font itself.

After patching the Fontmap.GS, the font can be found and the *.eps file is displayed correctly.

I'm attaching both the reproducer & patch.

My suggestion is to fix the Fontmap.GS (unless it breaks something for vanilla-build usage of Ghostscript), and requesting the that (URW)++ company renames the NimbusSansNarrow-BdOblique to NimbusSansNarrow-BoldOblique, so the value of /Fontname corresponds to filename.

Applied in:

http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=efc24229b0ba

With the addition of changing the font file name, so it is consistent.
