cropImageDataWithNativeLibrary function

Future<Uint8List?> cropImageDataWithNativeLibrary({ required Uint8List rawImage, required EditActionDetails editAction, required Rect cropRect, required int imageWidth, required int imageHeight, required bool isExtendedResizeImage, })

Crop image data using a native library.

This function crops image data using a native library for platforms other than web and desktop.

Parameters:

• Various parameters for image cropping and editing.

Returns: A Future that resolves to a Uint8List containing the cropped image data.

Example Usage: Not typically used directly; it's an internal implementation for specific platforms.

Implementation

Future<Uint8List?> cropImageDataWithNativeLibrary({
  required Uint8List rawImage,
  required EditActionDetails editAction,
  required Rect cropRect,
  required int imageWidth,
  required int imageHeight,
  required bool isExtendedResizeImage,
}) async {
  if (isExtendedResizeImage) {
    cropRect = await _getCropRect(
      cropRect: cropRect,
      imageHeight: imageHeight,
      imageWidth: imageWidth,
      rawImage: rawImage,
    );
  }

  final EditActionDetails action = editAction;

  final int rotateAngle = action.rotateAngle.toInt();
  final bool flipHorizontal = action.flipY;
  final bool flipVertical = action.flipX;
  final Uint8List img = rawImage;

  final ImageEditorOption option = ImageEditorOption();

  if (action.needCrop) {
    option.addOption(ClipOption.fromRect(cropRect));
  }

  if (action.needFlip) {
    option.addOption(
        FlipOption(horizontal: flipHorizontal, vertical: flipVertical));
  }

  if (action.hasRotateAngle) {
    option.addOption(RotateOption(rotateAngle));
  }

  option.outputFormat = const OutputFormat.png();

  final Uint8List? result = await ImageEditor.editImage(
    image: img,
    imageEditorOption: option,
