A new cairo snapshot 1.15.4 is now available from: http://cairographics.org/snapshots/cairo-1.15.4.tar.xz
which can be verified with: http://cairographics.org/snapshots/cairo-1.15.4.tar.xz.sha1 4e5d28697ac5a750a071edcf4a99e8af8d7c04b2 cairo-1.15.4.tar.xz http://cairographics.org/snapshots/cairo-1.15.4.tar.xz.sha1.asc (signed by Bryce Harrington) Additionally, a git clone of the source tree: git clone git://git.cairographics.org/git/cairo will include a signed 1.15.4 tag which points to a commit named: 9fe6683cb105354e86ea649ba7a13052c7edc757 which can be verified with: git verify-tag 1.15.4 and can be checked out with a command such as: git checkout -b build 1.15.4 This new snapshot incorporates changes over the past year since the 1.15.2 snapshot, including all the fixes from the 1.14 release series. Of particular note in this snapshot is a wealth of work by Adrian Johnson to enhance PDF support, as well as numerous bug fixes provided by him and other contributors. For a complete log of changes since the last release, please see: http://cairographics.org/releases/ChangeLog.1.15.4 Features -------- * The PDF backend has gained support for a range of widely used features, including thumbnails, page labels, metadata, document outlines, structured text, hyperlinks, and tags. Tags permit adding logical info such as headings, tables, figures, etc. that facilitates indexing, accessibility, text reflow, searching, and extraction of the tagged items to other software. For details on this new PDF functionality, see: https://lists.cairographics.org/archives/cairo/2016-June/027427.html API Changes ----------- cairo_win32_surface_create_with_format Added a cairo API to set up Win32 surfaces for HDC with alpha channels. cairo_pdf_surface_add_outline cairo_pdf_surface_set_metadata cairo_pdf_surface_set_page_label cairo_pdf_surface_set_thumbnail_size cairo_tag_begin cairo_tag_end CAIRO_STATUS_TAG_ERROR New API for added PDF functionality (see above), and new error status item for problems relating to PDF tagging. CAIRO_STATUS_WIN32_GDI_ERROR CAIRO_STATUS_FREETYPE_ERROR CAIRO_STATUS_PNG_ERROR New error status items for handling of GDI, libfreetype, and libpng errors, respectively. Dependency Changes ------------------ None Performance Optimizations ------------------------- None Bug Fixes --------- * Bug fixes from 1.15.2 (see the 1.15.2 NEWS for details) * Fix playback of recording surfaces into PDF surfaces, where objects with negative coordinates were not getting drawn. To address this, the coordinate systems for PDF and PS have been changed to match cairo's coordinate system. This allows recording surfaces to be emitted in cairo coordinates, and results in the same origin being used for all operations when using the recording surface XObject. Test cases for PDF and PS have also been updated accordingly. (Bug #89232) * Fix "invalidfont" error on some printers when printing PDFs with embedded fonts that have glyphs (such as spaces) with num_contours == 0. (Bug #79897) * Fix missing glyphs such as thin dashes, which get scaled to 0 in userspace and thus have their drawing operations culled. (Bug #94615) * Fix other oddities caused by variously idiosyncratic fonts. * Fix deadlock when destruction of a scaled font indirectly triggers destruction of a second scaled font, causing the global cache to be locked twice. (Bug #93891) * Fix X errors reported to applications when shmdt() is called before the Attach request is processed, due to missing xcb and xlib calls. * Fix random failure in record-paint-alpha-clip-mast test case, caused by an incorrect assumption that a deferred clear can be skipped. (Bug #84330) * Fix crash when dealing with an XShmGetImage() failure, caused by a double free in _get_image_surface(). (Bug #91967) * Fix invalid execution of ASCII85 data by the PS interpreter that the image operator didn't use, by flushing the extraneous data after drawing the image. (Bug #84811) * Fix decoding of Adobe Photoshop's inverted CMYK JPEG files in PDF export. * Fix unbounded surface assertion in win32-print code. * Fix a data race in freed_pool discovered by Firefox's cairo usage. The patch adads atomic int load and store functions, with relaxed memory ordering. (Bug #90318) * Cleanup debugging text sent to stdout instead of log. (Bug #95227) * Fix build issue when using non-GNU strings utility. (Bug #88639) * Fix build of cairo modules as regular modules, not as versioned shared libaries. (Bug #29319) * Fix build on win32 using gcc 5.4. * Fix build of script backend to require zlib. * Update test suite reference images using Debian Jessie 64-bit and poppler current as of June, 2016. * Various improvements to documentation and tests, compiler warning fixes, and an assortment of code refactoring and cleanup. What is cairo ------------- Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), quartz, win32, and image buffers, as well as PDF, PostScript, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB. Cairo is free software and is available to be redistributed and/or modified under the terms of either the GNU Lesser General Public License (LGPL) version 2.1 or the Mozilla Public License (MPL) version 1.1.
