I need to change the image that is being edited

[wfettich]

Hi,
I need to apply a filter on the mage while it is being edited. I managed to do a CustomViewController that also contains a slider that sets a certain filter value. However I can't seem to find how to change the image that is being edited. Could someone help me with some pointers or an example ?

I create the editor using the helper functions: Mantis.cropViewController .. where I pass the image to edit. However I cannot seem to be able to change it after the editor was created.

Thank you.

Currently Mantis does not support the feature you mentioned.
Is the demo below is something you want? (I changed some code for a test)
If you can provide more details of your requirement, I will consider to add this support in a future version.

Yes, that's it. But I have my own slider that applies my filter to that image.

Do you think you could share the code for that demo ?

If you just want to have a test, you can add the code below to CropViewController, and remove private for property imageView in ImageContainer

    public func setImage(_ image: UIImage) {
        cropView.image = image
        ((cropView as! CropView).imageContainer as! ImageContainer).imageView.image = image
    }

The code is for test only. I need a better API to support this feature if needed.

Now you can have a test on this PR #387
