If loading Arial fails, try loading a font commonly installed on Linux
distros.
This means it continues to work on Windows, and will also just work on
most Linux machines (DejaVu Sans is widely available and often installed
by default).
Made a handful of UI tweaks:
- changed literal 'random' default seed to a blank (more intuitive I think, also a blank previously behaved the same as '0')
- moved toggles into a Gradio CheckboxGroup (somewhat subjective, but saves a little vertical space in the UI, and makes it easier to adjust toggles in code)
- changed default CFG scale to 7.5 and 5.0 to match official txt2img and img2img (the waifu-diffusion fork this ultimately borrows from changed them to 7.0 for some reason)
- raised some of the default limits somewhat:
- Steps from 150 -> 250 (the official command line version crashes at exactly 251, so seems like a reasonable limit)
- ~~Batch count 16 -> 40~~ Got changed to 250 before I committed anyway
- CFG scale 15.0 -> 30.0 (above 15 doesn't seem to affect k-diffusion much, but significantly impacts DDIM and PLMS up to about 50—maybe should be - higher?)
- inverted toggle names for clarity (both default on):
- 'Skip grid' -> 'Save grid'
- 'Skip save individual images' -> 'Save individual images'
Also:
- added separate --outdir_txt2img and --outdir_img2img command line args, which take priority over --outdir
- fixed flagging, some var names were only partially updated previously—note that CSV indicies were changed, so old log files will need deleted/renamed/etc
GFPGAN requires images in BGR color space. Using the wrong color space leads to color-shift of the face after it's put through GFPGAN. To fix, convert the color space before sending to GFPGAN and again when it's returned.
