============================================== --> + +<!-- [2.0 begin contents] ================================================== --> + + +<h2><a name="What_Is_This"></a>What is the GhostPDL Interpreter Framework?</h2> + +<p> +The GhostPDL interpreter framework (henceforth, just GhostPDL) is +a framework into which multiple interpreters can be fitted, together +with a set of interpreters for different input "languages".</p> +<p>The intent is that a build of GPDL will behave as much as possible +like a build of Ghostscript, but should be able to transparently +cope with as many different input formats as it has interpreters built +into it.</p> +<p>It can be built as a dynamic link library +(DLL) on Microsoft Windows, as a shared object on the +Linux, Unix and MacOS X platforms. With some changes, it could be built +as a static library.</p> +<p>The reason we dub it a "Framework" is that it is +designed to be modular, and to readily allow new interpreters to be +swapped in and out to extend and customise its capabilities.</p> + +<p>Jobs must be separated by <code>UEL</code> (Universal End of Language) +code sequences (or PJL fragments, which implicitly start with a +<code>UEL</code> marker).</p> + +<h2><a name="API"></a>The API</h2> + +<p>The API for GPDL (found in <a href="../pcl/pl/plapi.h">plapi.h</a>) +is deliberately designed to be nearly identical +to that for Ghostscript itself (found in <a href="../psi/iapi.h">iapi.h</a>). +Details of Ghostscript's API can be +found <a href="API.htm">here</a>, and we refer you to that. Only +differences from that API will be documented here. In particular +the differences in the handling of switches within the +<code>gsapi_init_with_args</code> are documented +<a href="#different_switches">here</a>.</p> +<p>Our intent is that existing users of the Ghostscript API should be +able to drop a GPDL DLL in as a replacement with little to no code +changes.</p> + +<h3><a name="run"></a>The run_string APIs</h3> + +<p>The <code>run_string</code> APIs have parameters for +<code>int user_errors</code> and <code>int *error_code</code>. +Within Ghostscript, these allow a caller to bypass the language's +standard error handling, and to trap errors externally. +This makes no sense within a printer implementation (and, in +particular, no sense for a postscript interpreter running +jobs within a JobServer loop as GPDL does). Thus these +parameters are kept for ABI compatibility, but are largely +ignored within the GPDL implementation of gsapi. +For sanity, pass 0 for <code>user_errors</code>, and expect +<code>*error_code</code> to be set to 0 on exit.</p> + +<h3><a name="string_vs_file"></a>String vs File functions</h3> + +<p>Some file types, such as Postscript and PCL, are designed to be +'streamable'; that is to say that the files can be fed in and +consumed as they are interpreted. Other file types, such as PDF or +XPS require the whole file to be available so that the interpreters +can seek back and forth within it to extract the data they require.</p> + +<p>Traditionally, Ghostscript has relied upon the caller knowing +which type of data is which; streamable data can be fed in to the +system using the <code>gsapi_run_string</code> APIs, and complete files +of data can be fed in using <code>gsapi_run_file</code> or +<code>gsapi_init_with_args</code> APIs. Streamable data contained +with a file is simple to deal with, as it's trivial for an interpreter +to read bytes from a file, but doing random access on a stream is +much harder.</p> + +<p>In systems where data is being streamed in, but it is required +to be available for random access, the entire stream must be buffered +for presentation to the language interpreters. With Ghostscript, +the responsibility for doing this fell to the caller. Unfortunately, +this means that the caller also has to be responsible for scanning +the incoming data to spot when it is in a format that requires +buffering. With the explosion of formats that GPDL supports this +quickly becomes unpalatable.</p> + +<p>While the caller is still free to do such buffering of data +itself, GPDL will do it automatically if required. If a language +spots that data being fed to it via the <code>gsapi_run_string</code> +APIs is in a format that requires buffering, the entire string of +data will be automatically collected together, and then be +represented internally to the <code>gsapi_run_file</code> API.</p> + +<p>The current implementation buffers the data in memory. Alternative +implementations could use a backing store if such a thing were +available. For server based applications the use of memory is not +likely to be a problem (assuming reasonably sized input files at least). +For printer integrations, it's entirely possible that no backing +store will be available, so RAM may be the only option. Integrators +may wish to place a limit on the size of files that can be buffered +in this way.</p> + +<h2><a name="executable"></a>The GPDL executable</h2> + +<p> +The GPDL executable is a small executable that loads the DLL/shared object, +and implements, pretty much, the interface described in the +<a href="Use.htm">usage documentation</a> for Ghostscript, but capable of +reading any of the configured languages. This executable provides all +the interaction with the windowing system, including image windows.</p> + +<p>Areas where the GPDL executable differs from the Ghostscript +executable are described <a href="#different_switches">below</a>. These +are primarily to do with (slightly) esoteric requirements when +running Postscript in an interactive environment. Whereas Ghostscript +is a generic Postscript interpreter, GPDL is unashamedly targeted +as a print processor.</p> + +<p> +The GPDL framework's library name and characteristics differ +for each platform:</p> + +<ul> +<li>The Win32 DLL <code>gpdldll32.dll</code> +can be used by multiple programs simultaneously, but only once +within each process.</li> + +<li>The Linux shared object <code>libgs.so</code> +can be used by multiple programs simultaneously.</li> +</ul> +<p> +The source for the executable is in <code>plw</code>*.* (Windows) +and <code>plx</code>*.* (Linux/Unix). +See these source files for examples of how to use the DLL.</p> + +<p> +At this stage, GhostPDL does not support multiple instances +of the interpreter within a single process.</p> + +<h2><a name="different_switches"></a>Differences in switches from Ghostscript</h3> + +<p>The <code>gsapi_init_with_args</code> API entrypoint takes a +set of arguments, which can include various switches. We document +the differences between Ghostscript's handling of switches and +GhostPDLs here. The GhostPDL executable directly maps parameters +given on the command-line into this list, so this list of differences +applies both to API calls and uses of the executable.</p> + +<p>GhostPDL does not support the <code>-_</code>, <code>-+</code>, +<code>-@</code>, <code>-B</code>, <code>-F</code>, <code>-M</code>, +<code>-N</code>, <code>-P</code>, <code>-u</code>, and <code>-X</code> +switches that Ghostscript does. + +<p>GhostPDL supports a few switches that the Ghostscript executable +does not.</p> + +<ul> + <li><b><code>-E #</code>:</b> Sets the "error reporting mode" +for PCL/PXL.</li> + <li><b><code>-H #x#x#x#</code>:</b> Sets the hardware margins to the +given left/bottom/right/top values (in points).</li> + <li><b><code>-j <string></code>:</b> Passes the string to the + PJL level.

We include these, +for now, as we are aware that not everyone upgrades with every release.</h4> +<ul> +<li> +<p>(9.53.0) As of 9.53.0, we have (re-)introduced the patch level to the version number, +this helps facilitate a revised policy on handling security related issues. +<p><strong>Note for GSView Users:</strong>The patch level addition breaks GSView 5 (it is +hardcoded to check for versions <code>704-999</code>. It is possible, but not guaranteed that +a GSView update might be forthcoming to resolve this. +</li> +<li> +<p>(9.52) As of 9.52, the Windows binaries released by the Ghostscript development +team are built with Microsoft Visual Studio 2019. As a result, Microsoft Windows XP and +earlier are no longer supported by these binaries. This does not imply we are, or will +start relying upon features only available in VS2019, so the <code>nmake</code> Makefiles +will continue to allow older Visual Studio versions (back to VS2005) to build Ghostscript. +</li> +<li> +<p>(9.52) <code>-dALLOWPSTRANSPARENCY</code>: The transparency compositor (and related +features), whilst we are improving it, remains sensitive to being driven correctly, and +incorrect use can have unexpected/undefined results. Hence, as part of improving security +we limited access to these operators, originally using the <code>-dSAFER</code> feature. +As we made "SAFER" the default mode, that became unacceptable, hence the new option +<code>-dALLOWPSTRANSPARENCY</code> which enables access to the operators. +</li> +<li> +<p>(9.50) There are a couple of subtle incompatibilities between the old and new SAFER +implementations. Firstly, as mentioned in the 9.50 release notes, SAFER now leaves +standard Postcript functionality unchanged (except for the file access limitations). +Secondly, the interaction with <code>save</code>/<code>restore</code> operations, +see <a href="Use.htm#Safer">SAFER</a>. +<p><strong>Important Note for Windows Users</strong>: +<br> +The file/path pattern matching is case sensitive, even on Windows. This is a +change in behaviour compared to the old code which, on Windows, was case +<i>in</i>sensitive. This is in recognition of changes in Windows behaviour, +in that it now supports (although does not enforce) case sensitivity. +</li> +<li> +<p>(9.27) The process of "tidying" the PostScript name space should have removed +only non-standard and undocumented operators. Nevertheless, it is possible that +any integrations or utilities that rely on those non-standard and undocumented +operators may stop working or may change behaviour. +<p>If you encounter such a case, please contact us (either the #ghostscript IRC channel, +or the gs-devel mailing list would be best), and we'll work with you to either find an +alternative solution or return the previous functionality, if there is genuinely no other +option. +<p>One case we know this has occurred is GSView 5 (and earlier). GSView 5 support for PDF +files relied upon internal use only features which are no longer available. GSView 5 will +still work as previously for PostScript files. For PDF files, users are encouraged to look +at <a href="https://www.mupdf.com">MuPDF</a>. +</li> +</ul> +<h3><a name="9.53.0_changelog"></a>Changelog</h3> +<p><strong>2020-09-10 22:47:09 +0800 +</strong> +<br>Sebastian Rasmussen <sebras@gmail.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=9a5ace846c8af91d047e59c87722d0c36e79e5d3">9a5ace846c8af91d047e59c87722d0c36e79e5d3</a> +<blockquote> +<p> + Bug 702884: Require jbig2dec 0.19 when building ghostscript.<br> +<br> + In practice this has been required since commit<br> + 9b5008aa2bc1c6a6acb2c6f90d1ef8d6bad9e66a.<br> +<br> +configure.ac<br> +<p> +</blockquote> +<hr> +<p><strong>2020-09-10 22:41:20 +0800 +</strong> +<br>Sebastian Rasmussen <sebras@gmail.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=53db58bd227c80375f00135045d36b66868732f4">53db58bd227c80375f00135045d36b66868732f4</a> +<blockquote> +<p> + Update jbig2dec stuff for 0.19 release.<br> +<br> +jbig2dec/CHANGES<br> +jbig2dec/jbig2.h<br> +jbig2dec/jbig2dec.1<br> +<p> +</blockquote> +<hr> +<p><strong>2020-09-09 11:50:12 +0100 +</strong> +<br>Robin Watts <Robin.Watts@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=45884ca68488ac470b894702bdd8da232743d8e4">45884ca68488ac470b894702bdd8da232743d8e4</a> +<blockquote> +<p> + Bug 702871: Fix GraphicsAlphaBits + Fill/Stroke issue.<br> +<br> + When we flush the alphabuffer, mapped_start and mapped_height are<br> + both set to zero.

When this flag is true the ASCII85Decode<br> + filter will silently accept just '~' as a valid termination for a string<br> + (should be '~>').<br> +<br> + However this is not the only way to initialise an Ascii85Decode filter,<br> + the PostScript token scanner can also use s_A85D_init_inline() which<br> + does not initialise the flag.
