How to reset all options in CropImageView?

[Sirelon]

Hi! Thank you for this library) I have a question. How to reset all options for CropImageView ? I mean the rotation, scale, translation? I want to reuse the view, but with new Image and without transformations which I early did.

When I use postRotate and postScale than the next image which I set won't crop. the error is java.lang.IllegalArgumentException: x + width must be <= bitmap.width() in BitmapCropTask.java:151 The same occurs if I setImageMatrix(new Matrix())

How can I reuse CropImageView with initial options?

I have implemented some trick for this option. Just recreate UCropImageView :-) I am sure, that it is not good solution, but if anyone want to achieve this now, than he can use this approach. I published gist with ReusableUCropView

And thank you for this great library 👍

You can add this method to your extension of CropImageView to reset both scale and rotation:

public void reset() {
        final Drawable drawable = getDrawable();
        if (drawable == null) {
            return;
        }

        float drawableWidth = drawable.getIntrinsicWidth();
        float drawableHeight = drawable.getIntrinsicHeight();

        setupInitialImagePosition(drawableWidth, drawableHeight);
    }

Of course, there's no clean way to just extend CropImageView, you will need to extend UCropView, OverlayView, GestureCropImageView as well.

This reset feature for both rotation and scaling is very handy (can prevent unintentional cropping) so I hope it would get included in the next version.

The simple way is: just remove the UcropView and add a new one

public void reset() {
        setTargetAspectRatio(0f);
        setImageToWrapCropBounds(false);
        zoomInImage(getMinScale());
        setImageToWrapCropBounds();
    }

this is work for me
