Jagged artifacts in raster graphics, such as those caused by resizing a bitmap image without preserving its aspect ratio.
Origin: jaggy or jagged with diminutive -ie and plural -s.
"Jaggies" is the informal name for artifacts in raster images, most frequently from aliasing, which in turn is often caused by non-linear mixing effects producing high-frequency components or missing or poor anti-aliasing filtering prior to sampling. Jaggies are stairlike lines that appear where there should be smooth straight lines or curves. For example, when a nominally straight, un-aliased line steps across one pixel, a dogleg occurs halfway through the line, where it crosses the threshold from one pixel to the other. Jaggies should not be confused with most compression artifacts, which are a different phenomenon.
The New Hacker's Dictionary
The ‘stairstep’ effect observable when an edge (esp. a linear edge of very shallow or steep slope) is rendered on a pixel device (as opposed to a vector display).
