Can CropRotateEditor Open with the Image Fitted by Height or Width?

[yangheecho]

Is it possible to display the image as fitHeight or fitWidth when opening the CropRotateEditor?

Could you clarify what you mean by "fitHeight or fitWidth"? Do you mean that if the image is initially scaled to fit the screen width, it should instead start zoomed in so that it fits the height?

[yangheecho]

Yes, exactly.
What I mean is that when the editor is initialized, I would like the image to be initially scaled to fill the editor by height (or by width) instead of using the default fit behavior.

For example, for a landscape image, rather than fitting it to the screen width and leaving empty space vertically, I want the image to start zoomed in so that its height matches the editor height, with the extra width extending beyond the screen and being accessible via panning (not cropped).

In short, I’m looking for a way to control the initial scale and positioning of the image when the CropRotateEditor opens, similar to fitHeight or fitWidth behavior.

Got it. To do that, set up a callback where you update the required scale factor directly in onInit, like this:

ProImageEditorCallbacks(
  cropRotateEditorCallbacks: CropRotateEditorCallbacks(
    onInit: () {
      final editor = editorKey.currentState!;

      /// Use the image size to calculate the required scale factor.
      final imageSize = editor.sizesManager.decodedImageSize;

      final cropEditor = editor.cropRotateEditor.currentState!;
      cropEditor.setScale(2);
    },
  ),
);

In that example, I just set the scale factor to 2, but you'll need to calculate it based on your image size. Also, make sure to update to version 11.15.0, as I added the setScale method in that release.
