CRT effect

Applies a CRT effect, simulating an old cathode-ray tube television.

Adjusting the effect

The look of the CRT can be tuned with several settings:

• Line width and Line contrast control the visible scanlines. Enable Show vertical lines to draw the lines vertically instead of horizontally.
• Curvature bends the image outwards to imitate the bulge of an old screen (0 keeps it flat).
• Noise and Noise size add static grain. Noise Frequency sets how many times per second the noise is refreshed (0 freezes it).
• Vignetting, Vignetting alpha and Vignetting blur darken the corners of the screen.
• Interlaced Lines Speed animates the scanlines to make them scroll over time.
