Add notes for 1.3.16
Now, maybe we won't actually make a 1.3.16 snapshot, but these are all
the things that will be new in 1.4.0 compared to 1.3.14.

These include a function to query the current scaled +font: + + cairo_get_scaled_font + +New functions to query the reference count of all cairo objects: + + cairo_get_reference_count + + cairo_surface_get_reference_count + cairo_pattern_get_reference_count + + cairo_font_face_get_reference_count + cairo_scaled_font_get_reference_count + +And new functions to allow the use of user_data with any cairo object, +(previously this was only available on cairo_surface_t objects): + + cairo_set_user_data + cairo_get_user_data + + cairo_pattern_set_user_data + cairo_pattern_get_user_data + + cairo_scaled_font_set_user_data + cairo_scaled_font_get_user_data + + cairo_font_face_set_user_data + cairo_font_face_get_user_data + +Usability improvement for PDF/PS/SVG generation +----------------------------------------------- +In previous versions of cairo, generating single-page output with the +cairo-pdf, cairo-ps, or cairo-svg backends required a final call to +cairo_show_page. This was often quite confusing as people would port +functional code from a non-paginated backend and be totally mystified +as to why the output was blank until they learned to add this call. + +Now that call to cairo_show_page is optional, (it will be generated +implicitly if the user does not call it). So cairo_show_page is only +needed to explicitly separate multiple pages.p + +Greatly improved PDF output +--------------------------- +We are very happy to be able to announce that cairo-generated PDF +output will now have text that can be selected, cut-and-paste, and +searched with most capable PDF viewer applications. This is something +that was not ever possible with cairo 1.2. + +Also, the PDF output now has much more compact encoding of text than +before. Cairo is now much more careful to not embed multiple copies of +the same font at different sizes. It also compresses text and font +streams within the PDF output. + +Major bug fixes +--------------- + • Fixed radial gradients + + The rendering of radial gradients has been greatly improved. In + the cairo 1.2 series, there was a serious regression affecting + radial gradients---results would be very incorrect unless one of + the gradient circles had a radius of 0.0 and a center point within + the other circle. These bugs have now been fixed. + + • Fixed dashing + + Several fixes have been made to the implementation of dashed + stroking. Previously, some dashed, stroked rectangles would + mis-render and fill half of the rectangle with a large triangular + shape. This bug has now been fixed. + + • Fixed transformed images in PDF/PS output + + In previous versions of cairo, painting with an image-based source + surface pattern to the PDF or PS backends would cause many kinds + of incorrect results. One of the most common problems was that an + image would be repeated many times even when the user had + explicitly requested no repetition with CAIRO_EXTEND_NONE. These + bugs have now been fixed. + + • Eliminate errors from CAIRO_EXTEND_REFLECT and CAIRO_EXTEND_PAD + + In the 1.2 version of cairo any use of CAIRO_EXTEND_REFLECT or + CAIRO_EXTEND_PAD with a surface-based pattern resulted in an + error, (cairo would stop rendering). This bug has now been + fixed. + + Now, CAIRO_EXTEND_REFLECT should work properly with surface + patterns. + + CAIRO_EXTEND_PAD is still not working correctly, but it will now + simply behave as CAIRO_EXTEND_NONE rather than triggering the + error. + +New rewrite of quartz backend (still experimental) +-------------------------------------------------- +Cairo's quartz backend has been entirely rewritten and is now much +more efficient. This backend is still marked as experimental, not +supported, but it is now much closer to becoming an officially +supported backend. (For people that used the experimental nquartz +backend in previous snapshots, that implementation has now been +renamed from "nquartz" to "quartz" and has replaced the old quartz +backend.) + +Other bug fixes +--------------- + • cairo-svg: Fix bug that was preventing text from appearing in many + viewers + + • cairo-ft: Return correct metrics when hinting is off + + • Cairo 1.3.14 deadlocks in cairo_scaled_font_glyph_extents or + _cairo_ft_unscaled_font_lock_face + + https://bugs.freedesktop.org/show_bug.cgi?id=10035 + + • cairo crashes in cairo_create_simular if nil surface returned by + other->backend->create_similar + + https://bugs.freedesktop.org/show_bug.cgi?id=9844 + + • evolution crash to _cairo_gstate_backend_to_user() + https://bugs.freedesktop.org/show_bug.cgi?id=9906 + + • Fix memory leak in rectilinear stroking code + +Things not in this release +-------------------------- + • Solid surface pattern cache: This patch had been applied during + the 1.3.x series, but it was reverted due to some inter-thread + problems it caused. The patch is interesting since it made a big + benefit for text rendering performance---so we'll work to bring a + corrected version of this patch back as soon as possible. + Snapshot 1.3.14 (2006-02-13 Carl Worth <cworth@cworth.org>) =========================================================== This is the seventh development snapshot in the 1.3 series, (and there |
