* Increase use of SkMatrix::hasPerspective(), merge in has_perspective().Gravatar tomhudson@google.com2011-06-06
| | | | | | | | Unifies SkMatrix::hasPerspective(), has_perspective(), and manual tests of SkMatrix::getType & kPerspective_Mask. git-svn-id: http://skia.googlecode.com/svn/trunk@1517 2bbb7eff-a529-9590-31e7-b0007b416f81
* Change getConvexity() to now compute it if the value is set to kUnkown.Gravatar reed@google.com2011-05-16
| | | | | | | | Change behavior for degenerate paths: now those return kConvex instead of kUnknown git-svn-id: http://skia.googlecode.com/svn/trunk@1330 2bbb7eff-a529-9590-31e7-b0007b416f81

* clear the convex-hint in reset() and rewind(), to match its state in a newlyGravatar reed@google.com2011-02-07

* don't use SkAutoPathBoundsUpdate until after we've checked for degenerateGravatar reed@google.com2011-01-18
| | | | | | | | | | | | dimensions, otherwise we might set the bounds, only to then abort and not set any points. Fixes assert if you call addRoundRect(r, 10, 10) when r is inverted (i.e. r.fLeft > r.fRight) git-svn-id: http://skia.googlecode.com/svn/trunk@704 2bbb7eff-a529-9590-31e7-b0007b416f81
* SkPath::arcTo() will cause uninitialized memory reads in the following cases:Gravatar senorblanco@chromium.org2010-10-13
| | | | | | | | | | | | | | | | | | | - when the previous point in the path and (x1, y1) are coincident - when (x1, y1) and (x2, y2) are coincident These cause the setNormalize() calls to leave the "before" and "after" vectors uninitialized, respectively, which are then used to compute cosh and sinh. I chose to implement HTML5 canvas behaviour for these cases (as well as for the case where all three points are collinear): add a line to the first point, and bail. I think this is ok, since skia is mostly used for HTML5 browsers, and this case is degenerate anyway.
