It depends on what you're doing - in some cases Cubic gives better results. In addition nohalo and lohalo can take several minutes to scale an image. You can change the default tool option in preferences/tool options. > Also, it's probably safe to assume that if the user chooses an > interpolation type in the tool, they are saying something about the > quality of the results they are after vs speed.

I'd rather see it moved out of tool options and into preferences with a single setting in that case. In practice I fairly often copy a small section of an image and experiment with a cobination of blur and different downsizing algorithms. In addition, more upscaling options would be good, maybe after 2.10 - waifu2x, if unencumbered, would be a good candidate. So I think having the algorithm choice right there in scale image makes experimentation easier, and helps people dscover the option. So maybe a preference to say the default would be good. And hey! there is one :-) Liam -- Liam R. E.
