will be appended to a csv file `log/log.csv` in the `/sd` directory.

### Correct seeds for batches
If you use a seed of 1000 to generate two batches of two images each, four generated images will have seeds: `1000, 1001, 1002, 1003`.
Previous versions of the UI would produce `1000, x, 1001, x`, where x is an iamge that can't be generated by any seed.
### Resizing
There are three options for resizing input images in img2img mode:
- Just resize - simply resizes source image to target resolution, resulting in incorrect aspect ratio
- Crop and resize - resize source image preserving aspect ratio so that entirety of target resolution is occupied by it, and crop parts that stick out
- Resize and fill - resize source image preserving aspect ratio so that it entirely fits target resolution, and fill empty space by rows/columns from source image
Example:

### Loading
Gradio's loading graphic has a very negative effect on the processing speed onthe neural network.
My RTX 3090 makes images about 10% faster when the tab with gradio is not active. By defaul, the UI
now hides loading progress animation and replaces it with static "Loading..." text. Use
the --no-progressbar-hiding commandline option to revert this and show loading animations.
### Prompt validation
Stable Diffusion has a limit for imput text length. If your prompt is too long, you will get a
warning in the text output field, showing which parts of your text were truncated and consequently
ignored by the model.
