Using Transformation Object to Get Cropped Image Programmatically

[QuimboDiego]

If I have a Transformation object, is it possible to generate the image by applying its values directly, without presenting the CropViewController?

This feature isn’t currently supported in Mantis.
I’ll look into it when I have more time to assess how easy it would be to implement.

@QuimboDiego
I’ve found a way to achieve this. It involves using the CropInfo returned from cropViewControllerDidCrop instead of relying on the saved transformation to crop image programmatically. You’ll also need to apply this CropInfo to images that have the same aspect ratio as the one originally cropped.

If that matches your use case, I’ll share a code example when I get a chance — it should be doable.

Thanks for your reply! I’d really appreciate it if you could share a code example.

Please check this PR #463 to see if it works for you
Try "Headless Crop Demo" or search headlessCropDemoAction in the Example project

Thanks for the example, it works perfectly!
