NewInstance(ParcelFileDescriptor)

Create a BitmapRegionDecoder from the file descriptor.

[Android.Runtime.Register("newInstance", "(Landroid/os/ParcelFileDescriptor;)Landroid/graphics/BitmapRegionDecoder;", "", ApiSince=31)]
public static Android.Graphics.BitmapRegionDecoder NewInstance (Android.OS.ParcelFileDescriptor pfd);

[<Android.Runtime.Register("newInstance", "(Landroid/os/ParcelFileDescriptor;)Landroid/graphics/BitmapRegionDecoder;", "", ApiSince=31)>]
static member NewInstance : Android.OS.ParcelFileDescriptor -> Android.Graphics.BitmapRegionDecoder

Parameters

pfd

ParcelFileDescriptor

The parcel file descriptor containing the data to decode

Returns

BitmapRegionDecoder

Attributes

RegisterAttribute

Remarks

Create a BitmapRegionDecoder from the file descriptor. The position within the descriptor will not be changed when this returns, so the descriptor can be used again as is. Currently only the JPEG, PNG, WebP and HEIF formats are supported.
