This image uses the stroke-dasharray attribute on a circle to form "wedges" for use in pie charts. This "test image" renders perfectly when directly read by my Chrome, Firefox, and Safari, and no checker reported any SVG structural errors (w3.org, Commons SVG checker, and toolforge svg check).
A standard test image is a digital image file used across different institutions to test image processing and image compression algorithms. By using the same standard test images, different labs are able to compare results, both visually and quantitatively. The images are in many cases chosen to represent natural or typical images that a class ...
This allows for photorealistic images and renderings. For example, consider a circle of radius r. [14] The main pieces of information a program needs in order to draw this circle are An indication that what is to be drawn is a circle; the radius r; the location of the center point of the circle; stroke line style and color (possibly transparent)
SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by most web browsers. If ...

Tools allow manipulating primitive vector shapes: simple ones like rectangles, ellipses and arcs, as well as more complex objects like 3D boxes with adjustable perspectives, stars ...
Color space conversion is the translation of the representation of a color from one basis to another. This typically occurs in the context of converting an image that is represented in one color space to another color space, the goal being to make the translated image look as similar as possible to the original.
In a raster scan, an image is subdivided into a sequence of (usually horizontal) strips known as "scan lines".Each scan line can be transmitted in the form of an analog signal as it is read from the video source, as in television systems, or can be further divided into discrete pixels for processing in a computer system.
