Pin Reference Images

Goal of this feature is to provide an option to apply the canvas modifications to reference images based on the option selected in the Tool widget. This is implemented with four options position, zoom, rotate & mirror to allow them to be manipulated with canvas or image modifications .

This is a great mock-up of this feature from Bugzilla.

Pinned images, Un-Pinned images

Integrate Crop

This feature allows the reference images to be Cropped inside the Tool like the Crop Tool . Crop rectangle can be easily modified with the handles on the images and the sliders in the Tool box . So both are interconnected as well. The final crop action is in-destructible so the image is updated with original image and can be cropped differently again .

Sync Reference Images

This feature updates the image with latest modifications . Since references are not meant to be modified , but they can be modified like other files in Krita and uploaded with any rectifications . So this will keep track of any modifications done to them and uploads it correctly . This is done via QFileSystemWatcher class and this functionality exists in Krita for some layers already .

This is shown in the last part of the demo video in which the yellow line is shown in the reference images.

What's left

Documentation for the added features in Krita Manual and some minor code-style updates from the mentors code reviews.
