/**
* This lets you create a drawable based on an XML vector graphic.
*
* Note: To optimize for the re-drawing performance, one bitmap cache is created
* for each VectorDrawable. Therefore, referring to the same VectorDrawable means sharing the same
* bitmap cache. If these references don't agree upon on the same size, the bitmap will be recreated
* and redrawn every time size is changed. In other words, if a VectorDrawable is used for
* different sizes, it is more efficient to create multiple VectorDrawables, one for each size.
*
* VectorDrawable can be defined in an XML file with the <vector> element.
*
* The vector drawable has the following elements:
*
* <vector>
*
* - Used to define a vector drawable
*
* android:name- Defines the name of this vector drawable.
* android:width- Used to define the intrinsic width of the drawable.
* This support all the dimension units, normally specified with dp.
* android:height- Used to define the intrinsic height the drawable.
* This support all the dimension units, normally specified with dp.
* android:viewportWidth- Used to define the width of the viewport space. Viewport is basically
* the virtual canvas where the paths are drawn on.
* android:viewportHeight- Used to define the height of the viewport space. Viewport is basically
* the virtual canvas where the paths are drawn on.
* android:tint- The color to apply to the drawable as a tint. By default, no tint is applied.
* android:tintMode- The Porter-Duff blending mode for the tint color. The default value is src_in.
* android:autoMirrored- Indicates if the drawable needs to be mirrored when its layout direction is
* RTL (right-to-left).
* android:alpha- The opacity of this drawable.
*
*
*
*
* <group>- Defines a group of paths or subgroups, plus transformation information.
* The transformations are defined in the same coordinates as the viewport.
* And the transformations are applied in the order of scale, rotate then translate.
*
* android:name- Defines the name of the group.
* android:rotation- The degrees of rotation of the group.
* android:pivotX- The X coordinate of the pivot for the scale and rotation of the group.
* This is defined in the viewport space.
* android:pivotY- The Y coordinate of the pivot for the scale and rotation of the group.
* This is defined in the viewport space.
* android:scaleX- The amount of scale on the X Coordinate.
* android:scaleY- The amount of scale on the Y coordinate.
* android:translateX- The amount of translation on the X coordinate.
* This is defined in the viewport space.
* android:translateY- The amount of translation on the Y coordinate.
* This is defined in the viewport space.
*
*
*
*
* <path>- Defines paths to be drawn.
*
* android:name- Defines the name of the path.
* android:pathData- Defines path data using exactly same format as "d" attribute
* in the SVG's path data. This is defined in the viewport space.
* android:fillColor- Specifies the color used to fill the path. May be a color or, for SDK 24+, a color state list
* or a gradient color. If this property is animated, any value set by the animation will
* override the original value. No path fill is drawn if this property is not specified.
* android:strokeColor- Specifies the color used to draw the path outline. May be a color or, for SDK 24+, a color
* state list or a gradient color. If this property is animated, any value set by the animation will
* override the original value. No path outline is drawn if this property is not specified.
* android:strokeWidth- The width a path stroke.
* android:strokeAlpha- The opacity of a path stroke.
* android:fillAlpha- The opacity to fill the path with.
* android:trimPathStart- The fraction of the path to trim from the start, in the range from 0 to 1.
* android:trimPathEnd- The fraction of the path to trim from the end, in the range from 0 to 1.
* android:trimPathOffset- Shift trim region (allows showed region to include the start and end), in the range
* from 0 to 1.
* android:strokeLineCap- Sets the linecap for a stroked path: butt, round, square.
* android:strokeLineJoin- Sets the lineJoin for a stroked path: miter,round,bevel.
* android:strokeMiterLimit- Sets the Miter limit for a stroked path.
* android:fillType- Sets the fillType for a path. It is the same as SVG's "fill-rule" properties.
* For more details, see https://www.w3.org/TR/SVG/painting.html#FillRuleProperty
*
*
*
*
* <clip-path>- Defines path to be the current clip. Note that the clip path only apply to
* the current group and its children.
*
* android:name- Defines the name of the clip path.
* android:pathData- Defines clip path using the same format as "d" attribute
* in the SVG's path data.
*
*
* Here is a simple VectorDrawable in this vectordrawable.xml file.
*
* <vector xmlns:android="http://schemas.android.com/apk/res/android"
* android:height="64dp"
* android:width="64dp"
* android:viewportHeight="600"
* android:viewportWidth="600" >
* <group
* android:name="rotationGroup"
* android:pivotX="300.0"
* android:pivotY="300.0"
* android:rotation="45.0" >
* <path
* android:name="v"
* android:fillColor="#000000"
* android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
* </group>
* </vector>
