A linear, or axial, color gradient. In color science, a color gradient (also known as a color ramp or a color progression) specifies a range of position-dependent colors, usually used to fill a region. In assigning colors to a set of values, a gradient is a continuous colormap, a type of color scheme.
The Ben Day process is a printing and photoengraving technique for producing areas of gray or (with four-color printing) various colors by using fine patterns of ink on the paper. It was developed in 1879 [ 1 ] by illustrator and printer Benjamin Henry Day Jr. (son of 19th-century publisher Benjamin Henry Day ). [ 2 ]
Local binary patterns (LBP) is a type of visual descriptor used for classification in computer vision. LBP is the particular case of the Texture Spectrum model proposed in 1990. LBP is the particular case of the Texture Spectrum model proposed in 1990.

Color gradients can be linear or radial (circular), and can involve any number of colors as well as repeats. Opacity gradients can also be specified. Patterns are based on predefined raster or vector graphic objects, which can be repeated in x and y directions. Gradients and patterns can be animated and scripted. [39]
The pixels with the largest gradient values in the direction of the gradient become edge pixels, and edges may be traced in the direction perpendicular to the gradient direction. One example of an edge detection algorithm that uses gradients is the Canny edge detector. Image gradients can also be used for robust feature and texture matching.
Fill a region with a single color, gradient of colors, or a texture; Select a color using different color models, e.g., RGB, HSV, or by using a color dropper; Edit and convert between various color models. Add typed letters in various font styles; Remove imperfections from photo images; Composite editing using layers
MacDraw, introduced in 1984 with the Macintosh line of computers, was an early example of this class; recent examples are the commercial products Adobe Illustrator and CorelDRAW, and the free editors such as xfig or Inkscape. There are also many 2D graphics editors specialized for certain types of drawings such as electrical, electronic and ...
