@cmuratori What scaling algorithm did you use to molest the header-image on the about page?

@NoHatCoder Don't even get me started on that. Don't. Even. I'm going to write a custom one to scale Anna's drawings, since PS is so bad.1 reply 0 retweets 0 likes -

@NoHatCoder We had to set it to bilinear because cubic was _awful_ - super ringy and bad on the edges.1 reply 0 retweets 0 likes -

@cmuratori You need some form of supersampling for heavy downscaling, sampling method doesn't matter much, as long as you do enough samples.1 reply 0 retweets 0 likes -

@cmuratori I can't believe that Photoshop hasn't got this feature.1 reply 0 retweets 0 likes -

@NoHatCoder Not sure what you mean by "supersampling" in this case?1 reply 0 retweets 0 likes -

@cmuratori Lots of samples per output pixel. There is a wealth of different specific methods, all of them should produce better results.1 reply 0 retweets 0 likes -

@NoHatCoder That doesn't really make any sense? You know exactly all the pixels that are in the original image. You don't need to sample.1 reply 0 retweets 0 likes -

@NoHatCoder Any "dense sampling" of the image can still be trivially reduced to a weighted sum of the covered pixels.2 replies 0 retweets 0 likes -

@NoHatCoder So the question is just what weighting you use. Photoshop has the usual suspects...1 reply 0 retweets 0 likes
@NoHatCoder ... which of course haven't been updated since Mitchell, which was when computers were very slow and couldn't do certain things.
