For a list of items still needing work on the +cairo 1.2 roadmap, please see: + + http://cairographics.org/ROADMAP + +As can be seen in that list, there are no longer any API additions +left on the roadmap. Instead, there is a feature (PDF type 3 fonts) a +performance optimization (X server gradients) and a list of bug +fixes. This gives us a fair amount of freedom to cut the 1.2 release +at almost any point by deciding to defer remaining bug fixes to +subsequent maintenance releases such as 1.2.2 and 1.2.4. + +Before we will do that, we must first be wiling to commit to all the +new API additions. As a heads-up, there are a couple of potential API +changes being considered. (Note that these are changes to new API +introduced during 1.1 so these will not introduce API +incompatibilities compared to the stable 1.0 series). The changes +being considered are: + + cairo_get_group_target: may acquire x and y offset return + parameters. May also be eliminated in favor of + cairo_get_target assuming its role + + cairo_pdf_surface_set_dpi: + cairo_ps_surface_set_dpi: + cairo_svg_surface_set_dpi: These functions may be removed in favor + of a new cairo_surface_set_fallback_resolution + +Additionally there is the possibility of a slight change in the +semantics of cairo_set_line_width. We believe the current behavior of the sequence: + + cairo_set_line_width; ... change CTM ...; cairo_stroke; + +is buggy. It is currently behaving the same as: + + ... change CTM ...; cairo_set_line_width; cairo_stroke; + +We are considering fixing this bug before 1.2 with the hope that +nobody is already relying on the buggy behavior described here. Do +shout if you suspect you might be in that position. + +The items included in this snapshot (since the 1.1.4 snapshot) are +described below. + +API additions +------------- +The long-awaited group-rendering support is now available with the +following function calls: + + cairo_push_group + cairo_push_group_with_content + cairo_pop_group + cairo_pop_group_to_source + cairo_get_group_target + +This API provides a much more convenient mechanism for doing rendering +to an intermediate surface without the need to manually create a +temporary cairo_surface_t and a temporary cairo_t and clean them up +afterwards. + +Add the following missing get function to complement +cairo_surface_set_device_offset: + + cairo_surface_get_device_offset + +PDF backend (API addition) +-------------------------- +The PDF backend now provides for per-page size changes, (similar to +what the PostScript backend got in the 1.1.4 snapshot). The new API +is: + + cairo_pdf_surface_set_size + +Xlib backend (API additions) +---------------------------- +The following functions have been added to allow the extraction of +Xlib surface: + + cairo_xlib_surface_get_display + cairo_xlib_surface_get_drawable + cairo_xlib_surface_get_screen + cairo_xlib_surface_get_visual + cairo_xlib_surface_get_depth + +XCB backend (experimental) +-------------------------- +Update backend so that it now compiles with the recent XCB 0.9 release. + +Bug fixes and memory leak cleanup +--------------------------------- +Various little things, nothing too significant though. + Snapshot 1.1.4 (2006-05-03 Carl Worth <cworth@cworth.org>) ========================================================== This is the second in a series of snapshots working toward the @@ -66,7 +161,7 @@ A couple of memory leaks.
