| This is the cairo roadmap. |
| |
| Everything here is subject to change, but it is hoped that all of it |
| will be useful. If you want to influence, please feel free to get |
| involved with cairo (see http://cairographics.org ). |
| |
| The intent is for this to be a living document. We want both the users |
| of cairo, (GTK+, GNOME, Mozilla, Mono, etc. etc.) to let us know |
| features they need and dates by which they are needed so that we can |
| use those to guide our plans. |
| |
| Additionally, people who are actively developing cairo itself should |
| regularly update this document to reflect their current plans. If you |
| don't want to see a particular release happen without some essential |
| feature, then put that feature on the list and put your name next to |
| it to indicate you are working on it. |
| |
| Targets |
| ======= |
| Firefox 3.0 - http://www.mozilla.org/projects/firefox/roadmap.html |
| ------------------------------------------------------------------ |
| Firefox 3 (scheduled for early 2007?) is the first release expected to |
| use cairo for all rendering. In the meantime, development builds using |
| cairo are available |
| |
| Satisfying firefox 3 well requiring releasing new versions of cairo |
| before November 2006 (or earlier) that incorporate the patches coming |
| from mozilla, (clip querying), and much-improved performance. |
| |
| Themes and Schedules |
| ==================== |
| cairo-1.2.6 (no schedule; may not happen): |
| - 7744: Compile troubles on AIX |
| - PS/PDF Type1/Type3 problem with rotated font_matrices |
| |
| cairo-1.4 (October 2006): Better performance |
| - New tessellator |
| - New rasterization |
| - Finer-grained fallbacks for PS/PDF |
| |
| cairo 1.4.0 ideas (think performance!) |
| ====================================== |
| Implement framework for performance regression testing |
| |
| Investigate "low-hanging fruit" identified by David Turner (write test case for each) |
| |
| Look into speeding up pixman gradients |
| |
| Look into improving text positioning/placement on ARM (with no hardware floating-point) |
| |
| Look into speeding up dashing used for GTK+ focus rectangle |
| |
| Look into other GTK+ performance regressions as identified on performance-list |
| |
| xlib backend |
| Switch to server-side gradients for xlib backend |
| Fix X server to make server-side gradients faster |
| Switch to using XRenderAddTraps rather than XRenderCompositeTrapezoids |
| |
| Implement a non-trapezoid based rasterizer for use with xlib and other backends |
| |
| Cull geometry outside clip region bounds |
| |
| New tessellator |
| |
| Look into using alloca instead of malloc when copying glyphs/path/etc to edit |
| and use in one function and deallocate upon return. |
| |
| Look into generating EPS. That may be done using a new constructor for the |
| PS backend, or better, using an API similar to |
| cairo_svg_surface_restrict_to_version. The PDF backend needs a restrict_to |
| API at some point too. |
| |
| Look into the glyph cache. Moreover, make sure we are reusing scaled fonts |
| enough. |
| |
| User-font API |
| |
| Bugs to fix |
| ----------- |
| CAIRO_EXTEND_PAD is not implemented for surface patterns |
| CAIRO_FORMAT_RGB16_565 should be deprecated |
| |
| For other ideas that have been proposed for cairo but are not yet |
| scheduled on the roadmap of any particular release, please see the |
| TODO file next to this ROADMAP file. |
