During the cairo summit it was decided that this API is to freetype-
specific to be in the general cairo interface for now. This will
likely come back again soon as a cairo_ft-specific interface.
Chris rightfully complained that having a boolean function argument is
new in cairo_show_text_glyphs, and indeed avoiding them has been one
of the API design criteria for cairo. Trying to come up with alternatives,
Owen suggested using a flag type which nicely solves the problem AND
future-proofs such a complex API.
Please welcome _flags_t APIs to cairo.h
The adjustments done to the pixman matrix also need to be done for
XTransform. Since an XTransform is just a pixman_transform_t with
another name, we can reuse the conversion function.
where either pushes 'dict true' or 'false' so the true procedure needs to
consume the dictionary as well - for our purposes we just pop it off the
operand stack.
This reverts commit a341cb5a98.
The change introduced in that commit should not be needed and libtool
should just do the right thing. I cannot reproduce the problem
Chris was having no matter how hard I tried.
With --enable-gcov, make check aborts with gcov errors on check-link - it
appears that -lgcov is magic and requires explicit invovation on the
command-line.
Older versions of gcc complain about the use of a guard variable, and warn
that solid_color may be used uninitialized. As it happens the guard
variable is redundant and we can just use solid_color directly.
Avoid tessellating the path if we know that the target extents is zero.
Besides the rare occurrence when everything is clipped out, a zero-sized
surface is often intended as a no-op surface for benchmarking.
The PS emulation of the PDF text operators stores some data on the
user dict between calls to operators. When using the PDF text
operators in type 3 glyphs, the PDF operators were overwriting the
same data as the PDF operators in the page. Fix this by creating a new
dictionary to execute each type 3 glyph in.
This function emits the glyph to a null stream with the side effect
that other glyphs referenced by this user-font glyph will be added to
the font subsets.
If the gradient has constant alpha, then we can express it as a flattened
linear gradient. Otherwise, should the opacity vary across the gradient we
need to fallback.
This reverts commit 85ed37da33.
Adrian Johnson pointed out that iff the gradient has constant alpha then
it can be flattened. Reverting this commit in order to restore the
capability to handle gradient flattening.
