2018-10-20spectre-gs: Remove support for old ghostscriptChristian Persch2-22/+8
Now that we require a recent ghostscript, we can remove the support for older versions.
2018-10-20spectre-gs: Enforce minimum ghostscript versionChristian Persch1-1/+11
Ghostscript versions before 9.24 had a critical vulnerability allowing to escape -dSAFER; refuse to do anything if the version is less than 9.24. https://gitlab.freedesktop.org/libspectre/libspectre/issues/25

and where it originally came from so its clear where "undefined -21" came from in cases like https://bugzilla.gnome.org/show_bug.cgi?id=678500 https://bugs.freedesktop.org/show_bug.cgi?id=99395
2016-06-23Rotate documents correctly with newer libgs versionsMarek Kasik1-2/+106
Rotate result of rendering given by ghostscript when libgs >= 9.08. https://bugs.freedesktop.org/show_bug.cgi?id=76450

This reverts commit c0b7b178d455f00b21e6317376ab49324bddb340.
2014-06-09Rotate documents correctlyMarek Kasik4-31/+102
Set correct size of rendered images when a rotation is requested. Use "rotate" command to rotate documents instead of setting of "Orientation". Adjust offsets accordingly. Don't execute "setpagedevice" when rendering to "display" device. https://bugs.freedesktop.org/show_bug.cgi?id=76450
2012-11-03build: Use CPPFLAGS instead of CFLAGS for compiling flagsCarlos Garcia Campos1-4/+1

2010-12-04Allocate at least 1 page in doc->pagesMarek Kasik1-5/+5
Allocate at least 1 page if there are no %%Pages: or %%Page: comments in the PS file (#31512).
2010-10-30Fix a crash with documents containing an invalid %%Pages: commentCarlos Garcia Campos1-0/+2
When failed to allocate memory for pages because of invalid %%Pages: comment, set maxpages to 0 to ignore the comment. Problem spotted by Marek Kasik. Fixes bug #30867.
2010-06-01Fix rendering of files with doseps header and EOF comment missingCarlos Garcia Campos1-1/+8
Fixes bug #27830.
2010-06-01Remove unneeded #includeCarlos Garcia Campos1-1/+0
See bug #27734.
2010-06-01Make Ghostscript not look first in the current directory for library filesCarlos Garcia Campos2-3/+5

2010-04-06Fix a crash in pdf exporter when rendering failsCarlos Garcia Campos1-0/+6
2010-03-28Use the correct format string for DisplayHandle arg depending on the platformCarlos Garcia Campos1-2/+5
2010-02-21Fix compile warningCarlos Garcia Campos1-1/+1
2010-02-21Use spectre_gs_process() instead of spectre_gs_send_page() in pdf exporterCarlos Garcia Campos1-3/+40
When rendering with the display device we use a new gs instance for every page and we have to process prolog, setup and trailer for every page. PDF exporter is different, we use a single gs instance created in exporter_pdf_begin() and destroyed in exporter_pdf_end(). Now we use spectre_gs_process() to send prolog and setup in begin() and trailer in end() so that we just send the page contents in do_page(). Fixes bug #26592.
2010-02-21Make spectre_gs_process() public so that it can be used by exportersCarlos Garcia Campos2-1/+7
It's public in the internal private API
2010-02-21Ignore page order parameter of %%Pages if there's a %%PageOrder commentCarlos Garcia Campos1-3/+0
It caused problems in documents where there's a %%PageOrder after the %%Pages comment. See evince bug https://bugzilla.gnome.org/show_bug.cgi?id=585436
2010-02-03Add -no-undefined to LDFLAGS for building w32 dllHib Eris1-1/+1
2010-02-03Use _vscprintf instead of vsnprintf when availableHib Eris1-1/+7
On Windows, if output was truncated, vsnprintf() does not return the number of characters which would have been written to the string if enough space had been available. To work around this, use _vcsprintf() instead.

Fixes bug #25573.
2009-10-19fix some warnings of sscanf scanning signed but ending up in unsignedAlbert Astals Cid1-5/+5

Fixes bug #24132.
