The article 'A Pixel Is Not a Little Square' has sparked ongoing debate regarding the nature of pixels in digital imaging. Critics argue that the assertion that pixels are not physical squares is fundamentally flawed. Comments highlight that, despite possible variations in shape and layout arising from graphics hardware, pixels are treated as squares or rectangles in graphical programming and display. Many commenters emphasize the importance of recognizing pixels as rectangles for understanding graphics concepts like anti-aliasing, while others counter with theoretical arguments from signal sampling that describe pixels as point samples. The contention reveals a broader discussion on the intersection of theory and practical application in graphics, indicating changing technologies and perceptions over time.
