If it is not<br> + then the compositor must have pushed more than a single device, so it<br> + is not safe to behave as if the target of the compositor is our child<br> + device.<br> +<br> + Originally I had hoped to walk down the forwarding devices until we<br> + reach our device, but the actual behaviour of the pdf14 device in<br> + combination with the clist, when the final device is ps2write renders<br> + that all but impossible, as well as unnecessary.<br> +<br> + In this case the compositor action starts by defining a new device,<br> + It then pushes a pdf14_accum device (there are 3, one per device space)<br> + it then pushes the pdf14clist device in front of that. Finally it turns<br> + the device it first created into a forwarding device, and points its<br> + target at the original device.<br> +<br> + So we return with 3 new devices pushed, not just one. However, the<br> + final forwarding device is in fact forwarding to the subclassing device<br> + and the device reference counting magic is applied to the forwarding<br> + device, which means we don't need to dance around with the references<br> + to the subclassing device and child.<br> +<br> + We could detect this condition by checking the name of the target device<br> + of the pdf14clist forwarding device, but that isn't really any better<br> + than simply assuming that the compositor takes care of inserting new<br> + devices correctly. The pdf14_accum devices are not forwarding devices,<br> + they store the pdf14 device in a member called saved_pdev14, so we can't<br> + readily follow that either. Finally there is no way to determine if a<br> + device is a forwarding device, or a gx_device_pdf14_accum type which<br> + limits the amount of checking we cna perform.<br> +<br> + This is an interim commit to work around the problem, because we are<br> + about to do a release. A better fix which eliminates all (we hope)<br> + of the hidden assumptions and magic knowledge in the code here<br> + will be committed shortly, but may be too risky for the release.<br> +<br> +base/gdevsclass.c<br> +<p> +</blockquote> +<hr> +<p><strong>2021-03-01 14:35:15 +0000 +</strong> +<br>Chris Liddell <chris.liddell@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=109fb95822a5c4fa6d7dc99ed120149acafd8341">109fb95822a5c4fa6d7dc99ed120149acafd8341</a> +<blockquote> +<p> + Edit release highlights text<br> +<br> +doc/News.htm<br> +<p> +</blockquote> +<hr> +<p><strong>2021-03-01 11:58:04 +0000 +</strong> +<br>Chris Liddell <chris.liddell@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=79d04193b05200e1dd606c583c0b4e0b46520217">79d04193b05200e1dd606c583c0b4e0b46520217</a> +<blockquote> +<p> + Tidy up/add labels for URL destinations<br> +<br> + A few in VectorDevices.htm were wrong, and I added one in that file and a couple<br> + in Use.htm for convenience.<br> +<br> +doc/Use.htm<br> +doc/VectorDevices.htm<br> +<p> +</blockquote> +<hr> +<p><strong>2021-03-01 13:01:02 +0000 +</strong> +<br>Julian Smith <julian.smith@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=6a3a11e8e9a1420702867afdd555dff62ab7ba20">6a3a11e8e9a1420702867afdd555dff62ab7ba20</a> +<blockquote> +<p> + doc/VectorDevices.htm: added information about DOCX device.<br> +<br> +doc/VectorDevices.htm<br> +<p> +</blockquote> +<hr> +<p><strong>2021-02-25 09:36:18 -0800 +</strong> +<br>Ray Johnston <ray.johnston@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=fa775ffdd2ab6dff3b3178f9d36975308eeb9893">fa775ffdd2ab6dff3b3178f9d36975308eeb9893</a> +<blockquote> +<p> + Add documentation for NupControl (N-up printing) feature.<br> +<br> +doc/Use.htm<br> +<p> +</blockquote> +<hr> +<p><strong>2021-02-27 14:51:38 -0800 +</strong> +<br>Ray Johnston <ray.johnston@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=f06760e64c088ea24cd6a41c07cb459ecc690b05">f06760e64c088ea24cd6a41c07cb459ecc690b05</a> +<blockquote> +<p> + Add Colorant name for HalftoneType 5 components to -Zh output<br> +<br> +base/gsht1.c<br> +<p> +</blockquote> +<hr> +<p><strong>2021-02-26 08:03:56 +0000 +</strong> +<br>Chris Liddell <chris.liddell@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=1e30bb81fae075519db85af1bc7fb1658891627d">1e30bb81fae075519db85af1bc7fb1658891627d</a> +<blockquote> +<p> + Bug 703273: Prioritise Nonsymbolic over Symbolic font flag<br> +<br> + The font in this PDF has it descriptor flags set to 36, that is bit 3 (Symbolic)<br> + and bit 6 (Nonsymbolic) are both set.
