This replicates the img2img flow:
- Reset the canvas
- Resize the bbox to the image's aspect ratio at the optimal size for the selected model
- Add the image as a raster layer
- Resizes the layer to fit the bbox using the 'fill' strategy
After this completes, the user can immediately click Invoke and it will do img2img.
A new "session" just means to reset most settings to default values, excluding model.
There are a few things that need to be reset:
- Parameters state, except for models and things dependent on model selection (like VAE precision)
- Canvas state, except for the `modelBase`, which is dependent on the model selection
- Canvas staging area state
- LoRAs state
- HRF state
- Style presets state
We also select the canvas tab.
For new gallery sessions, we:
- Open the image viewer
- Set the right panel tab to `gallery`
And for new canvas sessions, we:
- Close the image viewer
- Set the right panel tab to `layers`
- Allow `uploadImage` util to accept `metadata` to embed in the image
- Update compositor to support `metadata` field when uploading rasterized composite layer
- Rework hotkey data to include the keys for each hotkey action.
- Add wrapper for `useHotkeys` that accepts a hotkey category and id. Automatically selects the key from the hotkey data.
- Add handling for macOS (cmd vs ctrl, option vs alt).
- Redo all hotkey descriptions, deleting nonexistant ones.
- Some `esc` hotkeys that just close whatever you are currently in are omitted due to their relative simplicity and intuitiveness.
- Canvas manages its own progress socket event listeners and progress event data.
- Remove cancellations listener jank.
- Dip into low-level redux subscription API to watch for queue status changes, clearing the last "global" progress event when the queue has nothing in progress. Could also do this in a useEffect I guess.
- Had to shuffle some things around to prevent circular imports, so there are a lot of tiny changes here.
Track various canvas states:
- Filtering an entity
- Transforming an entity
- Rasterizing an entity
- Compositing
- Busy (derived from all of the above)
Also track individual entity states:
- Locked
- Disabled
- All of type are hidden
- Has objects
- Interactable (derived from all of the above)
These states then gate various actions. For example:
- Cannot invoke while the canvas is busy.
- Cannot transform, filter, duplicate, or delete when the canvas is busy.
Tool interaction restrictions are not yet implemented.
So far, this includes:
- Save Canvas to Gallery
- Save Bbox to Gallery
- Send Bbox to Regional IP Adapter
- Send Bbox to Global IP Adapter
- Send Bbox to Control Layer
- Send Bbox to Raster Layer
To prevent losing all ephemeral canvas stage when switching tabs, we will refrain from destroying the canvas manager instance when its tab unmounts, and use the existing canvas manager instance on mount, if there is one.
One small change required in `CanvasStageModule` - a `setContainer` method to update the konva stage DOM element.
