It’s impossible to upscale an image correctly using the combination of size (cm) and PPI. The only way to correctly upscale is to enter the width (or height) in pixel.
Moreover, If I enter a size in cm, I’m forced to use a resolution in px/cm instead of keeping px/in that , unfortunately, it’s a standard.
It should work more accurately how Gigapixel was working (at least for the upscaling part).
Steps to reproduce issue:
- Open an image you want to upscale (TIF file)
- Set the W and H dimension in IN without changing any value
- Set the resolution to 360 px/in
- Try to dial 90cm in W dimension. PhotoAi will go crazy and will not work. It will not let you to go that size)
- Close PhotoAI and do it again by simply entering 12756 px in W. Not it will just work
Honestly I feel this is a massive step back from Gigapixel AI.I also don’t understand why the basic way to work is upscaling by a magnification factor, as who on earth would magnify by magnification factor and not by real-world size.
Moreover I don’t understand why there is still no plugin for upscaling like Gigapixel (even if Gigapixel was bugged until the last release 6.6.3 forcing the sRGB conversion every time, so I hope that once released, the color space conversion bug on PhotoAI will be fixed)
