An image gradient is a directional change in the intensity or color in an image. The gradient of the image is one of the fundamental building blocks in image processing . For example, the Canny edge detector uses image gradient for edge detection .
In its first year, Canva had more than 750,000 users. [12] In April 2014, Guy Kawasaki joined the company as its chief evangelist. [13] In 2015, Canva for Work was launched, focusing on marketing materials.

A gradient illustration, showing a gradation spectrum from black to white. Artists use a variety of methods to create gradation, depending upon the art medium, and the precise desired effect. Blending, shading, hatching and crosshatching are common methods. A fading effect can be created with pastels by using a torchon. [2]
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.
Mathematically, the gradient of a two-variable function (here the image intensity function) is at each image point a 2D vector with the components given by the derivatives in the horizontal and vertical directions. At each image point, the gradient vector points in the direction of largest possible intensity increase, and the length of the ...
and an external gradient is given by: G e ( f ) = f ⊕ b − f {\displaystyle G_{e}(f)=f\oplus b-f} . The internal and external gradients are "thinner" than the gradient, but the gradient peaks are located on the edges, whereas the internal and external ones are located at each side of the edges.
Milos Uzan scored a season-high 19 points to help No. 6 Houston rally for a 62-58 victory over No. 13 Arizona in Big 12 play on Saturday afternoon at Tucson, Ariz.
A gradient line going from opaque to transparent, for instance, can be used to have a darker foreground color fade into a lighter background color. The UI is highly customizable, and the user can freely move dialogs or adjust button sizes and such.
