Image analysis wrong conversion to Jpeg on iOS

[dtkdt100]

Steps to Reproduce

Download example app, run analysis_image_filter_picker.dart app. The result image analysis (even without filter) will be colored in blue and not in original colors as the preview. It happens only after converting the image to jpeg.

When tried to manually convert the image to jpeg using image, it works in vertical mode but not in horizontal images. In vertical mode it show the original colors, but when rotating the image starts to change its colors. I thought that the problem is in the order of the image, but changed it to all options with no success.

Expected results

The colors of the analysis should be the same as the preview.

Actual results

it looks like the app has blue filter, although it doesn't

hi . i have been work around and found solution

FutureOr<Uint8List> _convertBra8888fromJpeg(
  Bgra8888Image data,
) async {
  return img.encodePng(
    img.Image.fromBytes(
      width: data.width,
      height: data.height,
      bytes: data.planes[0].bytes.buffer,
      order: img.ChannelOrder.bgra,
    ),
  );
}

using package image can resolve this issue
