- Create separate object types for brush and eraser lines, instead of a single type that has a `tool` field.
- Create new object type for rect shapes.
- Add logic to schemas to migrate old object types to new.
- Update renderers & reducers.
Create intermediary nanostores for values required by the event handlers. This allows the event handlers to be purely imperative, with no reactivity: instead of recreating/setting the handlers when a dependent piece of state changes, we use nanostores' imperative API to access dependent state.
For example, some handlers depend on brush size. If we used the standard declarative `useSelector` API, we'd need to recreate the event handler callback each time the brush size changed. This can be costly.
An intermediate `$brushSize` nanostore is set in a `useLayoutEffect()`, which responds to changes to the redux store. Then, in the event handler, we use the imperative API to access the brush size: `$brushSize.get()`.
This change allows the event handler logic to be shared with the pending canvas v2, and also more easily tested. It's a noticeable perf improvement, too, especially when changing brush size.
When a control adapter processor config is changed, if we were already processing an image, that batch is immediately canceled. This prevents the processed image from getting stuck in a weird state if you change or reset the processor at the right (err, wrong?) moment.
- Update internal state for control adapters to track processor batches, instead of just having a flag indicating if the image is processing. Add a slice migration to not break the user's existing app state.
- Update preprocessor listener with more sophisticated logic to handle canceling the batch and resetting the processed image when the config changes or is reset.
- Fixed error handling that erroneously showed "failed to queue graph" errors when an active listener instance is canceled, need to check the abort signal.
This is largely an internal change, and it should have been this way from the start - less tip-toeing around layer types. The user-facing change is when you click an IP Adapter layer, it is highlighted. That's it.
Turns out, it's more efficient to just use the bbox logic for empty mask calculations. We already track if if the bbox needs updating, so this calculation does minimal work.
The dedicated calculation wasn't able to use the bbox tracking so it ran far more often than the bbox calculation.
Removed the "fast" bbox calculation logic, bc the new logic means we are continually updating the bbox in the background - not only when the user switches to the move tool and/or selects a layer.
The bbox calculation logic is split out from the bbox rendering logic to support this.
Result - better perf overall, with the empty mask handling retained.
When layer metadata is stored, the layer IDs are included. When recalling the metadata, we need to assign fresh IDs, else we can end up with multiple layers with the same ID, which of course causes all sorts of issues.
When invoking with control layers, we were creating and uploading the mask images on every enqueue, even when the mask didn't change. The mask image can be cached to greatly reduce the number of uploads.
With this change, we are a bit smarter about the mask images:
- Check if there is an uploaded mask image name
- If so, attempt to retrieve its DTO. Typically it will be in the RTKQ cache, so there is no network request, but it will make a network request if not cached to confirm the image actually exists on the server.
- If we don't have an uploaded mask image name, or the request fails, we go ahead and upload the generated blob
- Update the layer's state with a reference to this uploaded image for next time
- Continue as before
Any time we modify the mask (drawing/erasing, resetting the layer), we invalidate that cached image name (set it to null).
We now only upload images when we need to and generation starts faster.
When recalling metadata and/or using control image dimensions, it was possible to set a width or height that was not a multiple of 8, resulting in generation failures.
Added a `clamp` option to the w/h actions to fix this. The option is used for all untrusted sources - everything except for the w/h number inputs, which clamp the values themselves.
Firefox v125.0.3 and below has a bug where `mouseenter` events are fired continually during mouse moves. The issue isn't present on FF v126.0b6 Developer Edition. It's not clear if the issue is present on FF nightly, and we're not sure if it will actually be fixed in the stable v126 release.
The control layers drawing logic relied on on `mouseenter` events to create new lines, and `mousemove` to extend existing lines. On the affected version of FF, all line extensions are turned into new lines, resulting in very poor performance, noncontiguous lines, and way-too-big internal state.
To resolve this, the drawing handling was updated to not use `mouseenter` at all. As a bonus, resolving this issue has resulted in simpler logic for drawing on the canvas.
- Add set of metadata handlers for the control layers CAs
- Use these conditionally depending on the active tab - when recalling on txt2img, the CAs go to control layers, else they go to the old CA area.
