Advanced scaling algorithms

Recommended Posts

Hi, I would like to ask for comprehending some new scaling algorithms into Affinity Photo. There is plenty of approaches beyond nearest neighbour, bilinear, bicubic and Lanczos: https://en.wikipedia.org/wiki/Image_scaling

Especially algorithms developed for pixel-art scaling provide amazing results when enlarging low-res images (Super 2xSal, Super Eagle, hqnx, xBRZ...).

 

Here's my suggestion:

 

1) add a new "Rescale" filter, which would allow user to choose scaling algorithm and target pixel layer size.

 

2) eventually add "Rasterize using... >" item to contextual menu over layers. Behind this item, in the second menu level, there could be the algorithms available for rasterizing. In some cases, the default rasterizing algorithm isn't always the best option, especially when working with screenshots, images with text in it, where readability and certain sharpness is desired even after rasterizing.

 

 

Thank you for considering! :)

These would be very useful for icon design too.

 

I think that the Rasterise commands should have more options too.

And I suppose these are there but still hidden...  :)

 

Where is the smoking gun?

Well... It could be a mistake, but it is the only voice in the menu that has the "..." at the end and doesn't present a further dialog, as the convention would suggest.  :ph34r:

Hi Paolo, Lojza,

The "..." after the Rasterise command is because if you rasterize a layer with FX applied, you will get a dialog asking you if you want to flatten the FX or keep it as an editable effect.

I agree it would be nice to have a few more options here regarding the resampling algorithms.

 

Yep, I noticed that, but it is there "always" not only when layer fx are applied, so was daring some more future options.

Also there are many other little hints hidden around the UI that make me really curious...  :P

Has this been added yet? It has been 3 whole years with no comment. At this rate I'll be using gimp mainly and affinity for the extra functions.
