Fork of BlueAmulet's fork of ESRGAN by Xinntao

NOTE: This repo is no longer being actively maintained. I highly recommend using chaiNNer instead, as it is still actively maintained and supports a lot more than this repo does.

This fork ports features over from my ESRGAN-Bot repository and adds a few more. It natively allows:

Tile size was recently removed! It is no longer needed for split/merge functionality!

To set your textures to seamless, use the --seamless flag. For regular tiled seamless mode, use --seamless tile. For mirrored seamless mode, use --seamless mirror. You can also add pixel-replication padding using --seamless replicate and alpha padding using --seamless alpha_pad.

To chain models, simply put one model name after another with a > in between (you can also use + if using bash to avoid issues), such as 1xDeJpeg.pth>4xESRGAN.pth note: To use model chaining, model names must be the complete full name without the path included, and the models must be present in your /models folder. You can still use full model paths to upscale with a single model.

For on-the-fly interpolation, you use this syntax: <model1_name>:<##>&<model2_name>:<##>, where the model name is the path to the model and ## is the numerical percentage to interpolate by. For example, model1:50&model2:50 would interpolate model1 and model2 by 50 each. The numbers should add up to 100. If you have trouble using : or &, either try putting the interpolation string in quotes or use @ or | respectively ("model1@50|model2@50").

To use 1 bit binary alpha transparency, set the --binary-alpha flag to True. When using --binary-alpha transparency, provide the optional --alpha-threshold to specify the alpha transparency threshold. 1 bit binary transparency is useful when upscaling images that require that the end result has 1 bit transparency, e.g. PSX games. If you want to include half transparency, use --ternary-alpha instead, which allows you to set the --alpha-boundary-offset threshold.

The default alpha mode is now none. There are also now 3 other modes to choose from:

To process images in reverse order, use --reverse. If needed, you can also skip existing files by using --skip-existing.

If you're upscaling images of the same size, you can do --cache-max-split-depth to only calculate the automatic tile size once to improve performance.
