Most graphics editing programs, such as Adobe Photoshop and GIMP, allow users to modify the basic blend modes, for example by applying different levels of opacity to the top "layer". The top "layer" is not necessarily a layer in the application; it may be applied with a painting or editing tool.

The GNU Image Manipulation Program, commonly known by its acronym GIMP (/ ɡ ɪ m p / ⓘ GHIMP), is a free and open-source raster graphics editor [3] used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is extensible by means of plugins ...
Flood fill, also called seed fill, is a flooding algorithm that determines and alters the area connected to a given node in a multi-dimensional array with some matching attribute. It is used in the "bucket" fill tool of paint programs to fill connected, similarly colored areas with a different color, and in games such as Go and Minesweeper for ...
It used lines and bézier curves to render infinitely scalable graphics. [3] [4] Illustrator was released in early 1987, [5] and became a commercialization of Adobe's in-house font development software and PostScript file format. Adobe Illustrator is the companion product of Adobe Photoshop.
A glass plate with opaque lines had to be fixed in front of the interlaced print with a few millimeters in between, so the lines on the screen formed a parallax barrier: from the right distance and angle each eye could only see the photographic strips shot from the corresponding angle. The article was illustrated with a diagram of the principle ...
A fuzzy outline of an image is gradually replaced by seven successive waves of bit streams that fill in the missing lines until the image arrives at its full resolution. Interlaced graphics were once [ when? ] widely used in web design and before that in the distribution of graphics files over bulletin board systems and other low-speed ...
