<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> 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> 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> 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> 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> 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> 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 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>
