The extra check makes sure zero length segments are not skipped when computing
the dash start state. This is needed so that we get proper line capping if, for
example, the first dash segment has zero length and we have a dash offset of
zero.
|
|
Face computation still works if a line has zero length, all that is needed is a
slope and a point. This patch fixes bug #5561 because the faces are initialized
even if the segment has zero length as expected by
_cairo_stroker_line_to_dashed.
|
|
This makes the slope calculation more accurate for dashed lines by computing it
once for the entire line instead for each individual dash segment. It also
adjusts stroker_line_to() to match the new convention for
stroker_add_sub_edge().
|
|
This makes line_to_dashed more like line_to by returning immediately on
degenerate paths. This is needed so that we can do the slope calculation for
the entire line.
|
|
Fixes the bug mentioned in b87726ee2aa0220b66ee4d97513c0ac89ffc4621 by reseting
the dash pattern for each new subpath. This is correct behaviour according to
the end of PDF Reference v1.6 section 4.3.2.
This commit now makes the dash-caps-joins test case pass for all
backends except for the PostScript backend.
|
|
This adds a new function which has as its only effect the elimination
of
the current point. This makes it much easier to use the various
cairo_arc calls when the initial line_to is not actually desired.
This function also unifies and generalizes the long-existing behavior
of cairo_line_to being treated as cairo_move_to when there is no
current point. With the addition of cairo_new_sub_path this becomes a
documented feature with similar behavior in cairo_curve_to as well.

(paint, mask, stroke, fill, and show_glyphs). Now, all 5 operations have backend functions, and all use a consistent convention for argument naming and ordering. The old fill_path has been replaced with a new fill. The old show_glyphs function was recently renamed to old_show_glyphs and has not yet been ported to the new show_glyphs, (so all backends have a NULL show_glyphs function). In fact, of the 5 new backend functions, fill is the only one that has an implementation in any backend. As part of this cleanup a new cairo_stroke_style_t object is introduced to capture the many settings unique to the stroke operation, (line_width, line_cap, line_join, miter_limit, dash, num_dashes, and dash_offset).
Track changes in surface backend from fill_path to fill.
Track the new canonical argument naming and ordering for the 5 drawing operations.
Move various stroke style settings into new cairo_stroke_style_t.
Drop NULL fill_path backend function which no longer exists.

Remove pen_regular field from the gstate.
Move stroke fallback from gstate to surface where it belongs.
Eliminate dependence on cairo_gstate_t object.
Fix to include just cairo-clip-private.h rather than cairo-gstate.private.h.

Move face-flipping from inside _cairo_stroker_add_caps to new _cairo_stroker_add_leading_cap variant of _cairo_stoker_add_cap.
Change to call _cairo_stroker_add_leading_cap or _cairo_stroker_add_trailing_cap as appropriate.
Remove dash-caps-joins from the XFAIL list and add reference image.

Add support for dashed splines. (The antialiasing quality isn't perfect, but at least the curves are dashed now).
|
|
Abstract the cap-addition code from the end of the stroke operation into a new _cairo_stroker_add_caps function.
Call the new _cairo_stroker_add_caps at the beginning of every move_to so that we get caps on every subpath and not just the last one.

Fix indentation.

(cairo_append_path): Rename cairo_copy_path_data, cairop_copy_path_data_flat, and cairo_append_path_data to cairo_copy_path, cairo_copy_path_flat, and cairo_append_path.
Add new cairo_path_t, containing a cairo_path_data_t array and an explicit length. Remove CAIRO_PATH_END_PATH terminator from cairo_path_data_t.
Rename the internal path object from cairo_path_t to cairo_path_real_t.

cairo_move_to_func, cairo_line_to_func, cairo_curve_to_func, and cairo_close_path_func.
cairo_path.last_move_point and cairo_path.current_point are now fixed-point not doubles for consistency.
Now accept 4 explicit function pointers rather than a structure. Eliminate unnecessary done_path callback.
Track change in _cairo_path_interpret. Code previously in done_path callback is now here immediately after call to _cairo_path_interpret.
Internal _cairo_path API modified to accept fixed-point data everywhere. Much cleaner this way.
Have to convert doubles to fixed-point to track changes in _cairo_path API.
Keep data in fixed-point rather than going through intermediate doubles. Track changes in _cairo_path API.
New function to help when working with freetype.

close_path instead of add_edge, add_spline, and done_sub_path. Much, much nicer.
Provide cairo_polygon_move_to and cairo_polygon_line_to instead of cairo_polygon_add_point.
Track change in cairo_polygon interface.

Use cairo_point_double_t not XPointDouble, (to avoid false dependency on X headers). Thanks to "Sasha V." <sasha@aftercode.net> for pointing these out.

Replace XFoo with cairo_foo for double and fixed
