Questions tagged [bounds]

In user interfaces and graphics, bounds refer to the size and location of a window or view.

In user interfaces and graphics, bounds refers to the size and location of a window or view. In 2D graphics, this is broken down into four parts. Combinations often used include:

  • x-location, y-location, width, and height.
  • x-location, y-location, right, bottom.

Likewise, in 3D graphics, bounds are often broken into 6 components:

  • x, y, z, width, height, depth
