[Feature Request]: Add a 'resize_by' param to '/sdapi/v1/img2img' API endpoint

[altoiddealer]

Is there an existing issue for this?

What would your feature do ?

In the UI > Img2Img Tab, there is a nifty way to set both Width and Height values simultaneously via the Resize by tab.

Currently, there is no such parameter in the /sdapi/v1/img2img API endpoint.

When using the API, the Width and Height values must be explicitly specified.

Current empty .json for reference:

img2img_input.json

As it stands, users are required to determine the Width and Height of their input image, and code their own calculations to yield the desired Width and Height.

Please add a resize_by parameter to /sdapi/v1/img2img

Proposed workflow

1. Use the '/sdapi/v1/img2img' API endpoint
2. Try dynamically upscaling images
3. It's not easy because there is no resize_by parameter
