Crop doesn't work on iOS about flutter_native_image HOT 7 CLOSED

I just proposed a fix for this issue, by moralizing the image before cropping the issue is gone. #25

from flutter_native_image.

Hmm I didn't write that function and I don't have a lot of time to investigate right now. Maybe @a-leblond can chime in and see if there is anything wrong? Thanks!

Hi !

It seems weird, I use this function on iOS and Android in one of my project to square crop images and it works fine on both.
I don't see anything wrong with your code ... Could you try this and tell us if it works ? It's the code I use in my app :

  var imgProperties = await FlutterNativeImage.getImageProperties(widget.imagefile.path);
  var croppedImage;
  if(imgProperties.width > imgProperties.height)
    croppedImage = await FlutterNativeImage.cropImage(widget.imagefile.path,
        (imgProperties.width~/2)-(imgProperties.height~/2), 0,
        imgProperties.height, imgProperties.height);
  else
    croppedImage = await FlutterNativeImage.cropImage(widget.imagefile.path,
        0, (imgProperties.height~/2)-(imgProperties.width~/2),
        imgProperties.width, imgProperties.width);

Thanks for sharing your code. I get the same result when using your code.

At the moment, my best guess is that it's somehow related to EXIF rotation data. AIUI, if the rotation data is ignored, the image will appear sideways. I'm wondering if bits of the library code respect the EXIF data and bits don't.

I'll do some further digging with 'normal' images and will report back.

Indeed, when I test with a static image that definitely isn't EXIF rotated, your code (and mine) works fine.

Hmmmm I had some issues with the EXIF and image, so I use flutter_native_image in my app and it works fine both with the camera and static images, on Android and iOS.

Maybe it's the camera package you are using ? I use image_picker to take photo with the camera, you could give it a try.

I'll look deeper in the flutter_native_image code to see if there is something wrong this week.

I've started migrating to image_picker, which should avoid this problem. (I'm also moving away from square cropped images).

So I'm happy to close this, as my need has gone away. But leaving it open for now in case others are interested...
