OH_ImageSourceNative

struct OH_ImageSourceNative

Overview

The struct describes the image source, which is encapsulated at the native layer and is used to create image data. The struct cannot be directly operated. Instead, functions must be called to create and release the struct and operate the fields in the struct.

You can create an OH_ImageSourceNative object in multiple ways, as described below.

API	Description
OH_ImageSourceNative_CreateFromUri	Creates an OH_ImageSourceNative object based on a URI.
OH_ImageSourceNative_CreateFromFd	Creates an OH_ImageSourceNative object based on a file descriptor.
OH_ImageSourceNative_CreateFromData	Creates an OH_ImageSourceNative object based on buffer data.
OH_ImageSourceNative_CreateFromRawFile	Creates an OH_ImageSourceNative object by using the raw file descriptor of an image resource file.
OH_ImageSourceNative_CreatePixelmap	Creates an OH_PixelmapNative object based on decoding options.
OH_ImageSourceNative_CreatePixelmapList	Creates an array of OH_PixelmapNative objects based on decoding options.

To release an OH_ImageSourceNative object, call OH_ImageSourceNative_Release.
