@ -3,25 +3,30 @@ these should be official releases from the cairo project as-is. If
changes are necessary, they should be documented below and the patch
file included in this directory.
We only include the relevant parts of each release (generally, src/*.[ch]),
as we have Makefile.in's that integrate into the Mozilla build system. For
documentation and similar, please see the official tarballs at
http://www.cairographics.org/.
VERSIONS:
cairo 0.4.0
libpixman 0.1.4
cairo 0.5.0
libpixman 0.1.5
PATCHES:
subdirs.diff - don't build test/ or doc/.
stdint.diff - select between inttypes.h, stdint.h, and mozstdint.h.
quartz.diff - update cairo quartz/atsui backend for 0.4.0, reenable.
xlib.diff - include X11/xlib.h in cairo-xlib.h - needed for Solaris.
stroke-extent.diff - fix calculation of stroke extents.
stdint.h - select between inttypes.h, stdint.h, and mozstdint.h.
dash-dos.diff - prevent DOS attack with dasharray.
icformat.diff - upstream patch to select appropriate depth
alphablend.diff - check for AlphaBlend usability at runtime (win32)
feature-tests.diff - change #if to #ifdef, and change
cairo-features.h.in to #define things based on mozilla configure
tests
allow-null-surface.diff - allow creating a cairo_t with a NULL
target surface
optimize-opaque-paint.diff - if cairo_paint_with_alpha is called
with alpha == 1.0, turn it into cairo_paint

Snapshot 0.5.0 (2005-05-17 Carl Worth <cworth@cworth.org>)
==========================================================
This is a pretty big, and fairly significant snapshot. It represents
between 2 and 3 months of solid work from a lot of people on improving
the API as much as possible. I'd like to express my appreciation and
congratulations to everyone who has worked on the big API Shakeup,
(whether in email battles over names, or fixing my silly bugs).
This snapshot will require some effort on the part of users, since
there are a _lot_ of API changes (ie. no cairo program ever written is
safe --- they're all broken now in at least one way). But, in spite of
that, we do encourage everyone to move their code to this snapshot as
soon as possible. And we're doing everything we can think of to make
the transition as smooth as possible.
The idea behind 0.5 is that we've tried to make every good API change
we could want now, and get them all done with. That is, between now
and the 1.0 release of cairo, we expect very few new API changes,
(though some will certainly sneak in). We will have some significant
additions, but the pain of moving code from cairo 0.4 to cairo 0.5
should be a one time experience, and things should be much smoother as
we continue to move toward cairo 1.0.
And with so many changes coming out for the first time in this 0.5
release, we really do need a lot of people trying this out to make
sure the ideas are solid before we freeze the API in preparation for
the 1.0 release.
OK, enough introduction. Here is a (not-quite-complete) description of
the API removals, changes and additions in this snapshot, (compared to
0.4.0)
API removals
============
The following public functions have been removed:
- cairo_set_target_*
This is a big change. See the description of cairo_create in
the API changes section for how to deal with this.
- cairo_set_alpha
Alpha blending hasn't gone away; there's just a much more
unified rendering model now. Almost all uses of
cairo_set_alpha will be trivially replaced with
cairo_set_source_rgba and a few others will be replaced just
as easily with cairo_paint_with_alpha.
- cairo_show_surface
Another useful function that we realized was muddling up the
rendering model. The replacement is quite easy:
cairo_set_source_surface and cairo_paint.
- cairo_matrix_create
- cairo_matrix_destroy
- cairo_matrix_copy
- cairo_matrix_get_affine
These functions supported an opaque cairo_matrix_t. We now
have an exposed cairo_matrix_t structure, so these can be
dropped.
- cairo_surface_set_repeat
- cairo_surface_set_matrix
- cairo_surface_set_filter
These properties don't belong on surfaces. If you were using
them, you'll just want to instead use
cairo_pattern_create_for_surface and then set these properties
on the pattern.
- cairo_copy
This was a confusing function and hopefully nobody will miss
it. But if you really don't find cairo_save/restore adequate,
let us know and we have another idea for a potential
replacement.
And while we're on the subject of removals, we carefully tightened up
the cairo header files so they no longer gratuitously include header
files that are not strictly necessary, (stdio.h, stdint.h, pixman.h,
Xrender.h, etc. and their dependencies). This may lead to some
surprising errors, so keep your eyes open for that.
API changes
===========
Here are some of the API changes that have occurred:
~ cairo_create(void) -> cairo_create(cairo_surface_t *)
This is the big change that breaks every program. The ability
to re-target a cairo_t was not particularly useful, but it did
introduce a lot of muddy semantic questions. To eliminate
that, cairo_create now requires its target surface to be
passed in at creation time. This isn't too hard to cope with
as the typical first operation after cairo_create was often
cairo_set_target_foo. So the order of those two swap and the
application instead has cairo_foo_surface_create, then
cairo_create.
~ cairo_current_* -> cairo_get_*
We had a strange mixture of cairo_get and cairo_current
functions. They've all been standardized on cairo_get, (though
note one is cairo_get_current_point).
~ CAIRO_OPERATOR_SRC -> CAIRO_OPERATOR_SOURCE
~ CAIRO_OPERATOR_OVER_REVERSE -> CAIRO_OPERATOR_DEST_OVER
Many of the cairo_operator_t symbolic values were renamed to
reduce the amount of abbreviation. The confusing "OP_REVERSE"
naming was also changed to use "DEST_OP" instead which is
easier to read and has wider acceptance in other
libraries/languages.
~ cairo_set_pattern -> cairo_set_source
~ cairo_set_rgb_color -> cairo_set_source_rgb
All of the various functions that changed the source
color/pattern were unified to use cairo_set_source names to
make the relation more clear.
~ cairo_transform_point -> cairo_user_to_device
~ cairo_transform_distance -> cairo_user_to_device_distance
~ cairo_inverse_transform_point -> cairo_device_to_user
~ cairo_inverse_transform_distance -> cairo_device_to_user_distance
These names just seemed a lot more clear.
~ cairo_init_clip -> cairo_reset_clip
~ cairo_concat_matrix -> cairo_transform
More abbreviation elimination
~ cairo_current_path -> cairo_copy_path
~ cairo_current_path_flat -> cairo_copy_path_flat
The former mechanism for examining the current path was a
function that required 3 or 4 callbacks. This was more
complexity than warranted in most situations. The new
cairo_copy_path function copies the current path into an
exposed data structure, and the documentation provides a
convenient idiom for navigating the path data.
API additions
-------------
+ cairo_paint
A generalized version of the painting operators cairo_stroke
and cairo_fill. The cairo_paint call applies the source paint
everywhere within the current clip region. Very useful for
clearing a surface to a solid color, or painting an image,
(see cairo_set_source_surface).
+ cairo_paint_with_alpha
Like cairo_paint but applying some alpha to the source,
(making the source paint translucent, eg. to blend an image on
top of another).
+ cairo_mask
A more generalized version of cairo_paint_with_alpha which
allows a pattern to specify the amount of translucence at each
point rather than using a constant value everywhere.
+ cairo_mask_surface
A convenience function on cairo_mask for when the mask pattern
is already contained within a surface.
+ cairo_surface_set_user_data
+ cairo_surface_get_user_data
+ cairo_font_face_set_user_data
+ cairo_font_face_get_user_data
Associate arbitrary data with a surface or font face for later
retrieval. Get notified when a surface or font face object is
destroyed.
+ cairo_surface_finish
Allows the user to instruct cairo to finish all of its
operations for a given surface. This provides a safe point for
doing things such as flushing and closing files that the
surface may have had open for writing.
+ cairo_fill_preserve
+ cairo_stroke_preserve
+ cairo_clip_preserve
One interesting change in cairo is that the path is no longer
part of the graphics state managed by
cairo_save/restore. This allows functions to construct paths
without interfering with the graphics state. But it prevents
the traditional idiom for fill-and-stroke:
cairo_save; cairo_fill; cairo_restore; cairo_stroke
Instead we know have alternate versions cairo cairo_fill,
cairo_stroke, and cairo_clip that preserve the current path
rather than consuming it. So the idiom now becomes simply:
cairo_fill_preserve; cairo_stroke
+ cairo_surface_write_to_png
+ cairo_surface_write_to_png_stream
In place of a single PNG backend, now a surface created
through any backend (except PDF currently) can be written out
to a PNG image.
+ cairo_image_surface_create_from_png
+ cairo_image_surface_create_from_png_stream
And its just as easy to load a PNG image into a surface as well.
+ cairo_append_path
With the new, exposed path data structure, it's now possible
to append bulk path data to the current path, (rather than
issuing a long sequence of cairo_move_to/line_to/curve_to
function calls).
Xlib and XCB backends
---------------------
Any cairo_format_t and Colormap arguments have been dropped from
cairo_xlib_surface_create. There are also two new
cairo_xlib|xcb_surface_create functions:
cairo_xlib|xcb_surface_create_for_bitmap
(Particular for creating A1 surfaces)
cairo_xlib|xcb_surface_create_with_xrender_format
(For any other surface types, not described by a Visual*)
All of these surface create functions now accept width and height. In
addition, there are new cairo_xlib|xcb_surface_set_size functions
which must be called each time a window that is underlying a surface
changes size.
Print backends (PS and PDF)
---------------------------
The old FILE* based interfaces have been eliminated. In their place we
have two different functions. One accepts a simple const char
*filename. The other is a more general function which accepts a
callback write function and a void* closure. This should allow the
flexibility needed to hook up with various stream object in many
languages.
In addition, when specifying the surface size during construction, the
units are now device-space units (ie. points) rather than inches. This
provides consistency with all the other surface types and also makes
it much easier to reason about the size of the surface when drawing to
it with the default identity matrix.
Finally, the DPI parameters, which are only needed to control the
quality of fallbacks, have been made optional. Nothing is required
during surface_create (300 DPI is assumed) and
cairo_ps|pdf_surface_set_dpi can be used to set alternate values if
needed.
Font system
-----------
Owen very graciously listened to feedback after the big font rework he
had done for 0.4, and came up with way to improve it even more. In 0.4
there was a cairo_font_t that was always pre-scaled. Now, there is an
unscaled cairo_font_face_t which is easier to construct, (eg. no
scaling matrix required) and work with, (it can be scaled and
transformed after being set on the graphics state). And the font size
manipulation functions are much easier. You can set an explicit size
and read/modify/write the font matrix with:
cairo_set_font_size
cairo_get_font_matrix
cairo_set_font_matrix
(Previously you could only multiply in a scale factor or a matrix.) A
pleasant side effect is that we can (and do) now have a default font
size that is reasonable, as opposed to the old default height of one
device-space unit which was useless until scaled.
Of course, the old pre-scaled font had allowed some performance
benefits when getting many metrics for a font. Those benefits are
still made available through the new cairo_scaled_font_t. And a
cairo_font_face_t can be "promoted" to a cairo_scaled_font_t by
suppling a font_matrix and the desired CTM.
Quartz backend
--------------
Tim Rowley put in the work to bring the Quartz backend back after it
had been disabled in the 0.4.0 snapshot. He was not able to bring back
the function that allows one to create a cairo_font_t from an ATSUI
style:
cairo_font_t *
cairo_atsui_font_create (ATSUStyle style);
because he didn't have a test case for it. If you care about this
function, please provide a fairly minimal test and we'll try to bring
it back in an upcoming snapshot.

* Replace PNG backend with an image_surface function to save a PNG
image.
* Split cairo_format_t into two things:
- An enumeration that determines the "capabilities" of a surface -
A vs. ARGB. vs. RGB
- An enumeration that determines a specific in-memory representation
of data. (A1/A8/ARGB32/etc.. Could be extensible to things like
RGBA32_BYTES_NONPREMULTIPLIED. Some consistent naming convention would
be be good.)
One issue here is that some interfaces, like cairo_surface_create_similar()
might be useful with either one. We might want to create an A1 surface
compatible with the backend (are there examples other than A1? Should
bilevel just be another "capability"?), or we might want to just create
an alpha surface without caring about the depth.
If we want to support this, we could do something like:
typedef enum cairo_pixel_format_t {
CAIRO_PIXEL_FORMAT_A8 = CAIRO_FORMAT_ALPHA,
CAIRO_PIXEL_FORMAT_RGB24 = CAIRO_FORMAT_RGB,
CAIRO_PIXEL_FORMAT_A1,
};
To allow passing either in.
(I don't particularly like this idea for create_similar() because then you
aren't really saying ALPHA-dont-care, you are saying ALPHA-8. I think it
would be better to have a separate path for create_similar_with_pixel_format()
if we need that. But it might be useful for cairo_image_surface_create() ...
people are going to screw up and pass CAIRO_FORMAT_RGB into that, and if it
"just worked" that would save people trouble....)

## (We might end up doing this anyway to support other compilers.)

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## dummy dependencies for each header file. Too bad gcc doesn't do

Selects the font into the given device context and changes the
map mode and world transformation of the device context to match
that of the font. This function is intended for use when using
layout APIs such as Uniscribe to do text layout with the
Cairo font. After finishing using the device context, you must call

<span class="structname">cairo_matrix_t</span> is used throughout
Cairo to represents between different coordinates spaces.
A <span class="structname">cairo_matrix</span> holds an affine
transformation, such as a scale, rotation, or shear, or a
combination of those. Mathematically, the effect of an affine
transformation on a point (<tt class="literal">x</tt>,<tt class="literal">y</tt>) is given by:
</p><pre class="programlisting">
x_new = x * a + y * c + tx;
y_new = x * b + y * d + ty;
</pre><p>
The parameters <tt class="literal">a</tt>, <tt class="literal">b</tt>,
<tt class="literal">c</tt>, <tt class="literal">d</tt>, <tt class="literal">tx</tt>,
<tt class="literal">ty</tt> can be retrieved with
<a href="cairo-cairo-matrix-t.html#cairo-matrix-get-affine"><tt class="function">cairo_matrix_get_affine()</tt></a> and set with <a href="cairo-cairo-matrix-t.html#cairo-matrix-get-affine"><tt class="function">cairo_matrix_get_affine()</tt></a>.
</p><p>
The primary use of transformation matrices in Cairo is as the
current transformation matrix in a <a href="cairo-cairo-t.html#cairo-t"><span class="type">cairo_t</span></a>. The current
transformation matrix gives the transformation from user space
coordinates to device coordinates. See <a href="cairo-cairo-t.html#cairo-set-matrix"><tt class="function">cairo_set_matrix()</tt></a>,

<para><indexterm><primary>types</primary><secondary>cairo_matrix</secondary></indexterm><indexterm><primary/></indexterm>
<structname>cairo_matrix_t</structname> is used throughout
Cairo to represents between different coordinates spaces.
A <structname>cairo_matrix</structname> holds an affine
transformation, such as a scale, rotation, or shear, or a
combination of those. Mathematically, the effect of an affine
transformation on a point (<literal>x</literal>,<literal>y</literal>) is given by:
</para>
<programlisting>
x_new = x * a + y * c + tx;
y_new = x * b + y * d + ty;
</programlisting>
<para>
The parameters <literal>a</literal>, <literal>b</literal>,
<literal>c</literal>, <literal>d</literal>, <literal>tx</literal>,
<literal>ty</literal> can be retrieved with
cairo_matrix_get_affine() and set with cairo_matrix_get_affine().
</para>
<para>
The primary use of transformation matrices in Cairo is as the
current transformation matrix in a #cairo_t. The current
transformation matrix gives the transformation from user space
coordinates to device coordinates. See cairo_set_matrix(),
cairo_current_matrix().

You must be careful when using this function in a library or in a

share the same <link linkend="FT-Face"><type>FT_Face</type></link> object. For this reason, you must call
<link linkend="cairo-ft-lock"><function>cairo_ft_lock()</function></link> before locking any face objects, and
<link linkend="cairo-ft-unlock"><function>cairo_ft_unlock()</function></link> after you are done. (These functions are not yet

<structname>cairo_matrix_t</structname> is used throughout
Cairo to represents between different coordinates spaces.
A <structname>cairo_matrix</structname> holds an affine
transformation, such as a scale, rotation, or shear, or a
combination of those. Mathematically, the effect of an affine
transformation on a point (<literal>x</literal>,<literal>y</literal>) is given by:
</para>
<programlisting>
x_new = x * a + y * c + tx;
y_new = x * b + y * d + ty;
</programlisting>
<para>
The parameters <literal>a</literal>, <literal>b</literal>,
<literal>c</literal>, <literal>d</literal>, <literal>tx</literal>,
<literal>ty</literal> can be retrieved with
<link linkend="cairo-matrix-get-affine"><function>cairo_matrix_get_affine()</function></link> and set with <link linkend="cairo-matrix-get-affine"><function>cairo_matrix_get_affine()</function></link>.
</para>
<para>
The primary use of transformation matrices in Cairo is as the
current transformation matrix in a <link linkend="cairo-t"><type>cairo_t</type></link>. The current
transformation matrix gives the transformation from user space
coordinates to device coordinates. See <link linkend="cairo-set-matrix"><function>cairo_set_matrix()</function></link>,

"Approximation of circular arcs by cubic poynomials", Michael
Goldapp, Computer Aided Geometric Design 8 (1991) 227-238, provides
various values of h along with error analysis for each.
From that paper, a very practical value of h is:
h = 4/3 * tan(angle/4)
This value does not give the spline with minimal error, but it does
provide a very good approximation, (6th-order convergence), and the
error expression is quite simple, (see the comment for
_arc_error_normalized).

isn't really what we want since:
(1.0 - epsilon) * 0xffff = 0xfffe
In other words, given an input range of [0.0, 1.0], we have an
infinitely small range tha maps to the output value 0xffff,
(while having large, uniformly sized input ranges for all
other output values). This is undesirable, particularly when
we want to do optimizations for "opaque" colors specfied as
floating-point.
