I thought px was an abbreviation of pixel which doesn't have a dimension?
- Tagbert 5mo agoPixels have pitch, which is the distance between pixels. That is what is usually meant when talking about px as a measurement. It is analogous to dpi or ppi or the metric version.
- ethmarks 5mo agoDoes the pitch describe the distance between the edges of the pixels or between the centers?
- Tagbert 5mo agocenter to center.
- aptly_yclept 5mo agoTo expand on what the previous said, here's a link to a seminal paper on pixels - "A pixel is not a little square" by Alvy Ray Smith. https://alvyray.com/Memos/CG/Microsoft/6_pixel.pdf https://alvyray.com/Memos/CG/Microsoft/6_pixel.pdf
