HeifWriter
class HeifWriter : AutoCloseable
Writes one or more still images (of the same dimensions) into a heif file.
This class currently supports three input modes: INPUT_MODE_BUFFER, INPUT_MODE_SURFACE, or INPUT_MODE_BITMAP.
The general sequence (in pseudo-code) to write a heif file using this class is as follows:
1) Construct the writer:HeifWriter heifwriter = new HeifWriter(...);
2) If using surface input mode, obtain the input surface:Surface surface = heifwriter.getInputSurface();
3) Call start:heifwriter.start();
4) Depending on the chosen input mode, add one or more images using one of these methods:heifwriter.addYuvBuffer(...); Orheifwriter.addBitmap(...); Or render to the previously obtained surface
5) Call stop:heifwriter.stop(...);
6) Close the writer:heifwriter.close();
Please refer to the documentations on individual methods for the exact usage.

|---|---|
const Int |
The input mode where the client adds bitmaps. |

The input mode where the client renders the images to an input Surface created by the writer. |
Constants

INPUT_MODE_BUFFER
const val INPUT_MODE_BUFFER = 0: Int
The input mode where the client adds input buffers with YUV data.

INPUT_MODE_SURFACE
const val INPUT_MODE_SURFACE = 1: Int
The input mode where the client renders the images to an input Surface created by the writer. The input surface operates in single buffer mode. As a result, for use case where camera directly outputs to the input surface, this mode will not work because camera framework requires multiple buffers to operate in a pipeline fashion.
