- This update includes font documentation. SkFont_Reference.bmh was generated by running: bookmaker -b docs -i include/core/SkFont.h -t This creates a placeholder for examples and additional documentation. - More work done to exclude experimental/private symbols. Symbols that include "experimental_", "legacy_", "private_", "temporary_", "deprecated_" as part of their name (case-insensitive) are not referenced by the on-line docs and don't need comments. Tables built for online only include public symbols. - Better links for constructors, destructors, operators - Fixed some minor public interfaces - Removed _const crutch on operators - Keep includes inside 100 columns TBR=reed@google.com Docs-Preview: https://skia.org/?cl=171900 Bug: skia: Change-Id: I93b229c6625d800604671e05b82a14c06cb906d2 Reviewed-on: https://skia-review.googlesource.com/c/171900 Reviewed-by: Cary Clark <caryclark@skia.org> Commit-Queue: Cary Clark <caryclark@skia.org>

<a href='SkRect_Reference#SkRect'>SkRect</a> holds four <a href='undocumented#SkScalar'>SkScalar</a> coordinates describing the upper and

lower bounds of a rectangle. <a href='SkRect_Reference#SkRect'>SkRect</a> may be created from outer bounds or

from position, width, and height. <a href='SkRect_Reference#SkRect'>SkRect</a> describes an area; if its right

its top, it is considered empty.

<a href='SkRect_Reference#SkRect'>SkRect</a> can be constructed from int values to avoid compiler warnings that

Sets to bounds of <a href='SkPoint_Reference#SkPoint'>SkPoint</a> <a href='#SkRect_setBoundsNoCheck_pts'>pts</a> array with <a href='#SkRect_setBoundsNoCheck_count'>count</a> entries. If any <a href='SkPoint_Reference#SkPoint'>SkPoint</a> in <a href='#SkRect_setBoundsNoCheck_pts'>pts</a>

Sets <a href='SkRect_Reference#SkRect'>SkRect</a> to (0, 0, 0, 0).
|
|
|
|
Many other rectangles are empty; if left is equal to or greater than right,
|
|
or if top is equal to or greater than bottom. Setting all members to zero
|
|
is a convenience, but does not designate a special empty rectangle.

<a name='Intersection'></a>
|
|
|
|
<a href='SkRect_Reference#Rect'>Rects</a> intersect when they enclose a common area. To intersect, each of the pair
|
|
must describe area; <a href='#SkRect_fLeft'>fLeft</a> is less than <a href='#SkRect_fRight'>fRight</a>, and <a href='#SkRect_fTop'>fTop</a> is less than <a href='#SkRect_fBottom'>fBottom</a>;
|
|
<a href='#SkRect_isEmpty'>isEmpty</a>() returns false. The intersection of <a href='SkRect_Reference#Rect'>Rect</a> pair can be described by:
|
|
<code>(<a href='undocumented#max()'>max</a>(a.<a href='#SkRect_fLeft'>fLeft</a>, b.<a href='#SkRect_fLeft'>fLeft</a>), <a href='undocumented#max()'>max</a>(a.<a href='#SkRect_fTop'>fTop</a>, b.<a href='#SkRect_fTop'>fTop</a>),
|
|
<a href='undocumented#min()'>min</a>(a.<a href='#SkRect_fRight'>fRight</a>, b.<a href='#SkRect_fRight'>fRight</a>), <a href='undocumented#min()'>min</a>(a.<a href='#SkRect_fBottom'>fBottom</a>, b.<a href='#SkRect_fBottom'>fBottom</a>))</code>.
|
|
|
|
The intersection is only meaningful if the resulting <a href='SkRect_Reference#Rect'>Rect</a> is not empty and
|
|
describes an area: <a href='#SkRect_fLeft'>fLeft</a> is less than <a href='#SkRect_fRight'>fRight</a>, and <a href='#SkRect_fTop'>fTop</a> is less than <a href='#SkRect_fBottom'>fBottom</a>.
