Create a hardware bitmap backed by a HardwareBuffer.

[Android.Runtime.Register("wrapHardwareBuffer", "(Landroid/hardware/HardwareBuffer;Landroid/graphics/ColorSpace;)Landroid/graphics/Bitmap;", "", ApiSince=29)]
public static Android.Graphics.Bitmap? WrapHardwareBuffer (Android.Hardware.HardwareBuffer hardwareBuffer, Android.Graphics.ColorSpace? colorSpace);

[<Android.Runtime.Register("wrapHardwareBuffer", "(Landroid/hardware/HardwareBuffer;Landroid/graphics/ColorSpace;)Landroid/graphics/Bitmap;", "", ApiSince=29)>]
static member WrapHardwareBuffer : Android.Hardware.HardwareBuffer * Android.Graphics.ColorSpace -> Android.Graphics.Bitmap

Parameters

hardwareBuffer: HardwareBuffer

The HardwareBuffer to wrap.

colorSpace: ColorSpace

The color space of the bitmap. Must be a ColorSpace.Rgb colorspace. If null, SRGB is assumed.

Returns

Bitmap

A bitmap wrapping the buffer, or null if there was a problem creating the bitmap.

Attributes: RegisterAttribute

Remarks

Create a hardware bitmap backed by a HardwareBuffer.

The passed HardwareBuffer's usage flags must contain HardwareBuffer#USAGE_GPU_SAMPLED_IMAGE.

The bitmap will keep a reference to the buffer so that callers can safely close the HardwareBuffer without affecting the Bitmap. However the HardwareBuffer must not be modified while a wrapped Bitmap is accessing it. Doing so will result in undefined behavior.
