e7e4a03dd3 get-path-extents: Fix APPROX_EQUALS to round values on both sides of the comparison 2008-02-28 16:39:42 -08:00

602489b150 get-path-extents: Use APPROX_EQUALS instead of EQUALS for text path tests 
This is done grudgingly due to freetype rounding the coordinates
of the extents when hinting is enabled.

ecb54b9696 [test/get-path-extents] Don't use short-circuit && operators 
That causes some tests to be skipped if the preceding test failed.

c480eedbb5 Test and document extents of degenerate "dots" 
It's a common idiom to stroke degenerate sub-paths made with
cairo_move_to(x,y);cairo_rel_line_to(0,0) to draw dots. Test
that we get the desired extents from cairo_fill_extents,
cairo_stroke_extents, and cairo_path_extents for these cases.

Also document that the cairo_path_extents result is equivalent
to the limit of stroking with CAIRO_LINE_CAP_ROUND, (so that
these "dot" points are included), as the line width
approaches 0.0 .

55e0dddf04 Add cairo_path_extents testing to several cases missing it 
With these degenerate shapes, cairo_path_extents still returns
a zero-area rectangle, but with a non-zero offset.

c15cab8b68 Correct near-pangram to be an actual pangram 
This wasn't affecting the test quality at all, but it did annoy
me to see this mistake.

4177208be6 [cairo] Add cairo_path_extents() 
This new function gets the extents of the current path, whether
or not they would be inked by a 'fill'. It differs from
cairo_fill_extents() when the area enclosed by the path is 0.

Includes documentation and updated test.

7b1a0eddac [test/get-path-extents] Exercise cairo_scaled_font_text_extents() 
Compare cairo_scaled_font_text_extents() to cairo_text_extents() in
order to provide test coverage of cairo_scaled_font_text_extents().

3bf06c3366 [test/*] Create new surfaces using the group target. 
cairo_get_target() returns the original surface passed to
cairo_create(), and not the current destination as required when
testing drawing to the same surface using multiple contexts.

For completeness we also use the group target when creating similar
surfaces within the tests (to check that similar surfaces of similar
surfaces also work).

191e108b93 Add clip getters API + tests 
Add new public API methods:

void cairo_clip_extents (cairo_t *cr,                                               double *x1, double *y1,
    double *x2, double *y2);
cairo_rectangle_list_t *cairo_copy_clip_rectangles (cairo_t *);
void cairo_rectangle_list_destroy (cairo_rectangle_list_t *);

Also add 'get-clip' and 'get-path-extents' tests.
