yuv_to_png 0.0.2

A plugin to convert YUV image data into PNG image format.

yuv_to_png

A new 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.

Usage

To use this plugin:

1. install and import the plugin
2. Call YuvToPng.yuvToPng method passing the CameraImage variable
3. 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);

if there is an error you can use the next function to check if the image data is corrupted or not

        await precacheImage(Image.memory(imagedata).image, context,
        onError: (exception, stackTrace) {
      print('Failed to load image: $exception');
      imageRendered = false;
    });

if image data is corrupted you could simply use recurssion untill we get correct image data

The PNG data can then be used to display the image in Flutter using Image.memory() or as shown in the example application.

Optional

if you feel like buying me a coffe this will help me add more functions in the future like

• image cropping
• InputImage datatype to png

Note

please note that lensDirection effect the image rotation correction which might effect the image orientation if neglected

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.
