> A pixel is two dimensional, by definition.

A pixel is a point sample by definition.

An odd definition. A pixel is a physical object, a picture element in a display or sensor. The value of a pixel at a given time is a sample, but the sample isn't the pixel.

  • Definitions of technical things you aren’t familiar with tend to be odd.

    You are referring to a physical piece of a display panel. A representation of an image in software is a different thing. Hardware and software transforms the dsp signal of an image into voltages to drive the physical pixel. That process takes into account physical characteristics like dimensions.

    Oh btw physical pixels aren’t even square and each RGB channel is a separate size and shape.
