yuv_to_png
A Flutter plugin project that converts YUV image data to PNG image.
Overview
This package provides a Flutter plugin to convert YUV image data into PNG image format. It includes platform-specific implementation code for Android only as this from my knowledge happens only in Android systems .
The plugin takes in CameraImage image data in both yuv240 and nv21 and returns a PNG image in uint8;ist . This allows you to process camera frames, video frames etc captured natively in YUV format and convert them to PNG that can be displayed in Flutter when needed.
Usage
To use this plugin:
- install and import the plugin
- Call
YuvToPng.yuvToPng
method passing the CameraImage variable - it will handle the conversion and identification of the image formate and returns a
Uint8List
containing PNG image data
For example:
Uint8List png = YuvToPng.yuvToPng(cameraImage,
lensDirection: lensDirection);
The PNG data can then be used to display the image in Flutter using Image.memory()
or as shown in the example application.
Note
please note that lensDirection effect the image rotation correction which might effect the image orientation if neglected
