Typical Primitive Objects
Any particular vector file format supports only some kinds of primitive objects. Nearly all vector file formats support simple and fast-rendering primitive objects:
- Lines, polylines and polygons
- Bézier curves and bezigons
- Circles and ellipses
Most vector file formats support
- Text (in computer font formats such as TrueType where each letter is created from Bézier curves) or quadratics.
- color gradient
- Often, a bitmap image is considered as a primitive object. From the conceptual view, it behaves as a rectangle.
A few vector file formats support more complex objects as primitives:
- Many computer-aided design applications support splines and other curves, such as:
- Catmull-Rom splines
- NURBS
- iterated function systems
- superellipses and superellipsoids
- metaballs
- etc.
If an image stored in one vector file format is converted to another file format that supports all the primitive objects used in that particular image, then the conversion can be lossless.

Famous quotes containing the words typical, primitive and/or objects:
“Compare the history of the novel to that of rock ‘n’ roll. Both started out a minority taste, became a mass taste, and then splintered into several subgenres. Both have been the typical cultural expressions of classes and epochs. Both started out aggressively fighting for their share of attention, novels attacking the drama, the tract, and the poem, rock attacking jazz and pop and rolling over classical music.”
—W. T. Lhamon, U.S. educator, critic. “Material Differences,” Deliberate Speed: The Origins of a Cultural Style in the American 1950s, Smithsonian (1990)
“Through the din and desultoriness of noon, even in the most Oriental city, is seen the fresh and primitive and savage nature, in which Scythians and Ethiopians and Indians dwell. What is echo, what are light and shade, day and night, ocean and stars, earthquake and eclipse, there? The works of man are everywhere swallowed up in the immensity of nature. The AEgean Sea is but Lake Huron still to the Indian.”
—Henry David Thoreau (1817–1862)
“But what is classification but the perceiving that these objects are not chaotic, and are not foreign, but have a law which is also the law of the human mind?”
—Ralph Waldo Emerson (1803–1882)
