NEW BUGS
--------

#535836 - INTERNAL - Poor font rendering quality
reported by: raph
assigned: igorm

The text font in regression test file bulletin.pdf is
prone to dropouts, even at moderately high resolutions.
At 300 dpi, the right stem of the 'v' glyph has a
dropout immediately below the serif. Even at 600 dpi,
the bottom bowl of the 'g' glyph has a small dropout.
The font in question is Garamond-Light.

#535997 - USER - ps2pdf produces incorrect A4 page size
assign: ??

When ghostscript-7.04 is compiled with -DA4 (to select
the international standard office paper format), then
the default page format produced by ps2pdf and pdfwrite
is at the moment
/MediaBox [0 0 597 842]
The width (597) is wrong here (2 pt too large), because
the ISO A4 format is
210 mm = 210*72/25.4 pt = 595.27559 pt
297 mm = 297*72/25.4 pt = 841.88976 pt
Any correct PDF file formatted for A4 must have the
Adobe standard A4 bounding box [0 0 595 842]. 

#536863 - USER - Type11 layout bugs
assign: igorm?

Type11 (and I suspect Type42) incrementally loaded
composite glyphs have the sub glyphs in the wrong
position.
A potential patch is included.

#536877 - USER - Paper sizes wrong in gs_statd.ps
assign: ??

The file gs7.04/lib/gs_statd.ps defines macros for a large number of 
paper sizes, but unfortunately, many of them seem to be wrong by a few
points. 
Is seems the sizes currently listed were generated by
continuously dividing or multiplying the A4 point size
as a starting point. Unfortunately, this amplifies the
rounding error of the A4 point size and causes the
point measures to drift away considerably from the
official millimeter dimensions.

#537066 - USER - TrueType-Fonts with costum Encoding

User reports that Ghostscript cannot read pdf files with embedded 
truetype fonts which have a custom encoding.  A test file has been
requested.

#538033 - INTERNAL - need a check for // comments
reported by: giles
assigned: jackiem

We should have a regression test for detecting // style comments in 
portable files.

#538042 - CUSTOMER - /syntaxerror in --token--
customer: #1
assign: rayjj?

The file George.pdf fails in ghostscript even though Acrobat Reader
can display it fine.  The error ghostscript gives is /syntaxerror in 
--token--.

#538055 - CUSTOMER - /undefinedresult in --currentpoint--
customer: #440
assign: rayjj?

Test file 102.pdf fails with /undefinedresult in
--currentpoint-- with current CVS HEAD. Acrobat Reader
4 shows no errors.

#538267 - USER - Problems with Media Box in PDF and PS interpreter
assign: ??

I'm using gs 7.04 on Windows NT 4.0 to convert PDF and
PS files to TIFF G4. 
The PDF uses MediaBox, CropBox and Rotate commands.
Using Export to tiff with Acrobat 5.0 the image is ok.
Using Ghostscript adds a white area to my tiff file.
The dimensons of the tiff file are the same as
MediaBox. 

#538311 - USER - files missing from library archive
assign: giles?

When building a library archive (gslib.a) using
unixlink.mak some object files are missing from the
resulting library thus it is unusable. This is because
the makefile uses the following ar command:
$(AR) $(ARFLAGS) $(GSLIB_A) $(LIB_ARCHIVE_ALL)
where $(LIB_ARCHIVE_ALL) includes $(DEVS_ALL) that
contains .dev files instead of .o files.

#538398 - CUSTOMER - bad pdf that reader tolerates
assigned: rayjj
customer: #870

Test file kaercher.pdf renders fine under Acrobat
reader, but fails under Ghostscript.  Ray has a patch in
code-review for this bug.

#538428 - CUSTOMER - empty appearance streams
customer: #440
assign: rayjj?

The file EmptyAppearanceStream.pdf contains empty
appearance streams that apparently cause ghostscript to
fail when processing the file.
