* Correcting poping from Path objects
Poping from a 1-lengthed Path would yield an error due to not considering that the _segments attribute would be empty after deleting the last element.
* Correcting point function
Unspecified behavior if _segments is empty
* Correcting setter and getter of start and end
* add some failing Arc.intersect(Arc) tests
* implementing Arc.intersect(Arc)
This commit adds special handling in Arc.intersect() when the other
segment is an Arc, and when both segments are circular and non-rotated.
This particular case is common, and quick and easy to solve algebraically.
This commit fixes the failing tests added in the previous commit.
* Added method is_contained_by to the Path class
* Adding a requirements.txt file
Signed-off-by: David Romero <dromero.fisica@gmail.com>
* Correcting tests of is_contained_by
* Fixed document.flatten_group(~) for nested groups and added a test
* Add space for PEP8 conformance
* Add documentation for document.get_group()
* Use group_search_xpath to be consistent and customizable
* Fix lexical mistake in comments
* Fix grammar mistake in comments
* add Arc.__hash__()
This function returns a hash of the Arc parameters, providing a kind of
Arc object fingerprint.
* Arc: cache segment length
Computing the length of an Arc segment takes a relatively long time.
This commit teaches the Arc class to remember its segment length,
to avoid recomputing it. It invalidates the cache and recomputes the
segment length if any of the Arc parameters have changed.
* add some tests of Path.area()
These tests currently fail because area() doesn't deal with Arc segments.
Fix in the following commit.
* make Path.area() approximate arcs
Fixes#37.
* Path.area(): fixup tabs/spaces for python3
* added asin to imports
* added asin to imports
* minor improvements to style, performance, and docstring
* Basic Svg_Io_Sax
* Update to binary write
* Fixed SaxSvg Load, tweaked test.
* Couple tweaks.
* Couple tweaks to fit the dom parser api better
* Switch to iterparse for speed
* Used None matrix for identity in default case.
* Test Update for None Matrix
* add Line.point_to_t() and tests
These tests don't print anything while they run, and they use use the
assert() helpers from the unittest module.
* add Arc.point_to_t() and tests
These tests don't print anything while they run, and they use use the
assert() helpers from the unittest module.
* add a bunch of failing arc/line intersection tests
This commit contains a bunch of failing arc/line intersections that I
and other people have run into.
These tests don't print anything while they run, and they use use the
assert() helpers from the unittest module where possible.
All these tests are fixed in the following commit.
* better implementation of Arc.intersect(Line)
Fixesmathandy/svgpathtools#35.
This commit fixes all the arc/line intersection test cases added in the
previous commit.
This implementation provides special handling in Arc.intersect() when
`self` is a non-rotated Arc and `other_seg` is a Line. In this case
it uses the straight-forward closed-form solution to identify the
intersection points.
Rotated Arcs and Arcs intersecting with non-Line objects still use
the pre-existing intersection code, that part is totally untouched by
this commit.
