There's a technical challenge with outputting these values directly. `ImageField` does not store them, so the batch's `ImageField` collection does not have width and height for each image.
In order to set up the batch and pass along width and height for each image, we'd need to make a network request for each image when the user clicks Invoke. It would often be cached, but this will eventually create a scaling issue and poor user experience.
As a very simple workaround, users can output the batch image output into an `Image Primitive` node to access the width and height.
This change is implemented by adding some simple special handling when parsing the output fields for the `image_batch` node.
I'll keep this situation in mind when extending the batching system to other field types.
- Add special handling for `ImageBatchInvocation`
- Add input component for image collections, supporting multi-image upload and dnd
- Minor rework of some hooks for accessing node data
Rework uploadImage and uploadImages helpers and the RTK listener, ensuring gallery view isn't changed unexpectedly and preventing extraneous toasts.
Fix staging area save to gallery button to essentially make a copy of the image, instead of changing its intermediate status.
`CanvasCompositorModule` had a fairly inflexible API, only supporting compositing all raster layers or inpaint masks.
The API has been generalized work with a list of canvas entities. This enables `Merge Down` and `Merge Selected` functionality (though `Merge Selected` is not part of this set of changes).
We were scaling the unscaled image and mask down before doing the paste-back, but this adds an extraneous step & image output.
We can do the paste-back first, then scale to output size after. So instead of 2 resizes before the paste-back, we have 1 resize after.
The end result is the same.
We were:
- Incrementing `addedControlNets` or `addedT2IAdapters`
- Attempting to add it, but maybe failing and skipping
Need to swap the order of operations to prevent misreporting of added cnet/t2i.
I don't think this would ever actually cause problems.
