This image was scaled up using nearest-neighbor interpolation.Thus, the "jaggies" on the edges of the symbols became more prominent. Jaggies are artifacts in raster images, most frequently from aliasing, [1] 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.
The lasso (or "free form selection") is an editing tool available, with minor variations, in most digital image editing software [1] and some specific strategy games.It is often accessed from the standard main menu (in Photoshop, [2] Paint Tool SAI, [3] and GIMP, [4] as common examples), by clicking the icon of a dotted line shaped like a rope lasso, from which the common name arises.
Alpha compositing, allows for soft translucent edges when selecting images. There are a number of ways to silhouette an image with soft edges, including selecting the image or its background by sampling similar colors, selecting the edges by raster tracing, or converting a clipping path to a raster selection.
Overscan is a behaviour in certain television sets in which part of the input picture is cut off by the visible bounds of the screen. It exists because cathode-ray tube (CRT) television sets from the 1930s to the early 2000s were highly variable in how the video image was positioned within the borders of the screen.
In computer graphics, anti-aliasing improves the appearance of "jagged" polygon edges, or "jaggies", so they are smoothed out on the screen. However, it incurs a performance cost for the graphics card and uses more video memory. The level of anti-aliasing determines how smooth polygon edges are (and how much video memory it consumes).
Any content that is intended to extend to the edge of the paper must be extended beyond the trim line in order to produce bleed. Bleeds in the imperial system generally are 1/8 of an inch from where the cut is to be made. Bleeds in the metric system generally are 2mm-5mm from where the cut is to be made, often varying by printing company. Some ...
Cut-off (electronics), a state of negligible conduction. Cutoff (metalworking), a piercing operation used to cut a workpiece from the stock. Cutoff (meteorology), a high- or low-pressure system stuck in place due to a lack of steering currents. Cutoff (physics), a threshold value for a quantity.
A camera takes pictures and videos with an angle of just over 180 degrees, e.g. 220 degrees. These are then converted into a 360-degree object using software. Problems are often caused by stitching errors. This means that an incorrect combination of the images can result in an unclean cut edge that is difficult or impossible to remove.
