+Approximately 100 bugs have been fixed since the 8.63 release. + +<p> +Of particular note in this release are improvements to overprint and +spot color support in documents with transparency, improvements to PDF +and PS output, proper handling of PDF-specific text rendering modes and +support for reading AES-encrypted PDF documents. + +<p> +Also improved is handling of CJK text, especially in vertical writing +modes, memory footprint processing some files at high resolution and +support for using the system's default paper size on unix. + +<p> +The interpreter's handling of color spaces has been moved from +PostScript code to C. + +<p> The following <a href="http://bugs.ghostscript.com/">bugs</a> were +open at the time of the last release: <blockquote> +226943, +430175, +465936,

pages, +and some images render as white rectangles or fail completely with an +error. This is an outstanding bug, rather than a permanent change. +Pass -sDEVICE=x11 as a work around for these issues. + +<p> +In this release the C source files have been split into two new +directories.

This results in better quality and smaller files. + +However type 1 or 2 fonts which are too large for an arbitrary Ghostscript limit (> 65537 glyphs) can not be copied. This 'should' have fallen back to the old mechanism, but some data had been altered which led to this failing. + +The fix for this comprises 3 parts: + +1) Mmodified scan_cmap_text to save the data we modify for subsetting, and restore it if pdf_obtain_font_resource_unencoded fails, which then falls back to the 'default' type 3 mechanism (in case of future problems in this area). + +2) Increased the limit of glyphs (for type 1 or 2 fonts) in gs_copy_font. Added a new parameter 'max_reserved_glyphs'. If this is -1 then we reserve enough space for the number of glyphs in the original font. Otherwise we reserve space for the specified maximum. This limit only applies to font type 1 or 2, and is used by pdfwrite to avoid making excessively large font copies. + +3) Modified pdf_base_alloc so that if the font is large (and is not one of the standard 13 fonts), we don't allocate a complete copy for our 'subset', we only allocate as many glyphs as will fit in a standard Encoding, 256, plus one for the required .notdef making 257 in total. We also avoid making a second 'complete' copy of the font, because we will never write the complete font. + +</pre> +<p>[base/gdevpdtb.c base/gxfcopy.c base/gdevpdtc.c base/gxfcopy.h]</p> +</blockquote> + +<p><strong><a name="2008-12-05T073906.671710Z"></a> +2008-12-05T07:39:06.671710Z Alex Cherepanov</strong></p> +<blockquote> +<pre> +Check the whole Decode array to detect special cases of identity and inverse +decoding.
