Invoke is a leading creative engine for Stable Diffusion models, empowering professionals, artists, and enthusiasts to generate and create visual media using the latest AI-driven technologies. The solution offers an industry leading WebUI, and serves as the foundation for multiple commercial products.
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.
