Lecture 3: Antialiasing (20)

Is it possible to achieve this filtering without distorting the color? Or is that something that is consequence of antialiasing and simply must be edited later after filter and then sampling?

Also, is point-sampling used in drawing softwares (Microsoft paint, procreate, etc.)? If so, is there a way to make an "antialiazed" brush and would color distortion still occur if used to actively soften brush edges rather than filtering a single photo? Does this vary from application to application? And if so, how come drawing applications of the same era even seem to vary between "crisper" vs "softer" edges?

The slight color distortions in this image are sort of a natural effect of the averaging process we perform when supersampling. Different patterns of supersampling could result in differences in the antialiased image.

here's actually a post on someone looking to create a brush tool that does less antialiasing (https://graphicdesign.stackexchange.com/questions/150556/how-do-i-make-the-brush-tool-less-antialiased). Not too familiar with the specifics of different drawing applications, but I would imagine that the amount/method of antialiasing for different brushes varies!

In drawing applications (both pixel (i.e. photoshop) and vector based (i.e. illustrator) applications aliasing can be done layer by layer while ediitng or on export. I used to work as a photo editor and fixing aliasing / distortion issues when working with assets from a variety of file types and various sizes was actually quite the challenge as humans can pick up on minute issues pretty easily.
