|

<p>This defines how far a touch event can start away from the view. Typical
|
||
interface guidelines recommend touch targets that are at least 30 - 40
|
||
points/density-independent pixels.</p>
|
||
<p>For example, if a touchable view has a height of 20 the touchable height can be
|
||
extended to 40 with <code>hitSlop={{top: 10, bottom: 10, left: 0, right: 0}}</code></p>
|
||
<blockquote>
|
||
<p>The touch area never extends past the parent view bounds and the Z-index of
|
||
sibling views always takes precedence if a touch hits two overlapping views.</p>

|
||
<p>Whether this <code>View</code> needs to rendered offscreen and composited with an alpha in
|
||
order to preserve 100% correct colors and blending behavior. The default
|
||
(<code>false</code>) falls back to drawing the component and its children with an alpha
|
||
applied to the paint used to draw each element instead of rendering the full
|
||
component offscreen and compositing it back with an alpha value. This default
|
||
may be noticeable and undesired in the case where the <code>View</code> you are setting an
|
||
opacity on has multiple overlapping elements (e.g. multiple overlapping <code>View</code>s,
|
||
or text and a background).</p>
|
||
<p>Rendering offscreen to preserve correct alpha behavior is extremely expensive
|
||
and hard to debug for non-native developers, which is why it is not turned on by
|
||
default. If you do need to enable this property for an animation, consider
|
||
combining it with renderToHardwareTextureAndroid if the view <strong>contents</strong> are
|
||
static (i.e. it doesn't need to be redrawn each frame). If that property is
|
||
enabled, this View will be rendered off-screen once, saved in a hardware
|
||
texture, and then composited onto the screen with an alpha each frame without
|
||
having to switch rendering targets on the GPU.</p>

|

<p>Whether this <code>View</code> should render itself (and all of its children) into a single

||
hardware texture on the GPU.</p>
|
||
<p>On Android, this is useful for animations and interactions that only modify
|
||
opacity, rotation, translation, and/or scale: in those cases, the view doesn't
|
||
have to be redrawn and display lists don't need to be re-executed. The texture
|
||
can just be re-used and re-composited with different parameters. The downside is
|
||
that this can use up limited video memory, so this prop should be set back to
|
||
false at the end of the interaction/animation.</p>

|

<p>Whether this <code>View</code> should be rendered as a bitmap before compositing.</p>
|
||
<p>On iOS, this is useful for animations and interactions that do not modify this

||
component's dimensions nor its children; for example, when translating the
|
||
position of a static view, rasterization allows the renderer to reuse a cached
|
||
bitmap of a static view and quickly composite it during each frame.</p>
|

<p>Rasterization incurs an off-screen drawing pass and the bitmap consumes memory.

Test and measure when using this property.</p>
