What are jaggies?

Jaggies is a slang term for blurred spread lines that may appear in computer graphics. They usually occur in raster, also known as bitmap, images with reduced resolution. The lines resemble a staircase and appear instead of direct lines or curves at the edges of the image. When their size changes, the process called aliasing adds or removes pixels in such a way that the representation error appears, also known as an artifact. Artifacts often have a look similar to staircases because of this addition or pixel reading around the edges of the image. Graphics without a grid, known as vector graphics, relies on the mathematical formula instead of pixels to represent pictures. That's why vector graphics do not produce Jaggies.

animated computer graphics or videos can also have jaggies. Graphics time posterizacemoving is responsible for the production of these artifacts. This process describes what is happening visually when the number of frames in the video decreases but its speed remains the sameon.

Jaggies can be reduced in computer graphics through anti-aliasing. Anti-aliasing adds shaded pixels to the areas around the edges of the image to create a smoother look. Time anti-aliasing, also known as movement blur, can repair jaggies in animated graphics or video. In the video, this process is responsible for capturing a scene or picture for time, not only in one case. Time anti-aliasing causes the image to look as if it plunged throughout the screen.

Anti-aliasing on the entire FSAA (FSAA) is used in three-dimensional graphics cards to reduce jaggies in video game systems. The method uses anti-aliasing on all three-dimensional images on the screen. The most commonly used anti-aliasing technique in FSAA is too much sampling. Over-Sampling includes doubling or four times the resolution of each image. Images are then sampled to match the sizeby sewing the display.

It is assumed that the term "jaggies" came from the Atari's rescue video game on Fractalus! , which was released in 1985. One of the computer graphics in the game was not anti-valued. Due to the low resolution of the Atari system, artifacts were never excluded from the image and the developers have described the effect as "jagged". Later they named the enemies in the game "Jaggi" and even allegedly wanted to call the video game for Jaggi Lines .
