The interface is as follows: + + #include <cairo-win32.h> + + void + cairo_set_target_win32 (cairo_t *cr, + HDC hdc); + + cairo_surface_t * + cairo_win32_surface_create (HDC hdc); + + cairo_font_t * + cairo_win32_font_create_for_logfontw (LOGFONTW *logfont, + cairo_matrix_t *scale); + + cairo_status_t + cairo_win32_font_select_font (cairo_font_t *font, + HDC hdc); + + void + cairo_win32_font_done_font (cairo_font_t *font); + + double + cairo_win32_font_get_scale_factor (cairo_font_t *font); + +And see also the documentation at: + +http://cairographics.org/manual/cairo-Microsoft-Windows-Backend.html + +Disabled backend: quartz +------------------------ +Unfortunately, the quartz backend code is currently out of date with +respect to some recent backend interface changes. So, the quartz +backend is disabled in this snapshot. + +If the quartz backend is brought up-to-date before the next snapshot, +we would be glad to make a 0.4.1 snapshot that re-enables it, (we do +not expect many more big backend interface changes). + +API Changes +----------- +The font system has been revamped, (as Owen Taylor's work with +integrating pango and cairo gave us the first serious usage of the +non-toy font API). + +One fundamental, user-visible change is that the cairo_font_t object +now represents a font that is scaled to a particular device +resolution. Further changes are described below. + + cairo.h + ------- + Removed cairo_font_set_transform and cairo_font_current_transform. + + Added cairo_font_extents and cairo_font_glyph_extents. See + documentation for details: + + http://cairographics.org/manual/cairo-cairo-t.html#cairo-font-extents + + cairo-ft.h + ---------- + The cairo_ft_font API changed considerably. Please see the + documentation for details: + + http://cairographics.org/manual/cairo-FreeType-Fonts.html + +Performance +----------- +Make the fast-path clipping (pixel-aligned rectangles) faster. + +Add optimization for applying a constant alpha to a pattern. + +Optimize gradients that are horizontal or vertical in device space. + +Xlib: When RENDER is not available, use image surfaces for +intermediate surfaces rather than xlib surfaces. + +Backend-specific changes +------------------------ + Glitz + ----- + Major update to glitz backend. The output quality should now be just + as good as the image and xlib backends. + + Track changes to glitz 0.4.0. + + PDF + --- + Various improvements to produce more conformant output. + +Internals +--------- +David Reveman contributed a large re-work of the cairo_pattern_t +implementation, providing cleaner code and more optimization +opportunities. + + Backend interface changes + ------------------------- + Rework backend interface to accept patterns, not surfaces for source + and mask. + + Remove set_matrix, set_filter, and set_repeat functions. + + More sophisticated backend interface for image fallbacks, + ({acquire,release}_{source,dest}_image() and clone_similar). + +Bug fixes +--------- +Only install header files for backends that have been compiled. + +Fixed some rounding errors leading to incorrectly placed glyphs. + +Many other minor fixes. + Snapshot 0.3.0 (2005-01-21 Carl Worth <cworth@cworth.org>) ========================================================== Major API changes |
