nWidthnHeight

nWidthnHeight is a term sometimes seen in programming contexts to denote a value or parameter associated with both width and height. It is not a formal standard, but rather a naming convention that may appear in legacy code, generated headers, or API wrappers. The prefix n often signals an integer type in certain coding styles, and the combined word suggests a size specification that involves two dimensions.

In practice, nWidthnHeight can refer to either a pair of dimensions stored separately or a single packed value that encodes both width and height. A common low-level approach is to pack two 16-bit integers into a 32-bit value, for example by using width in the high 16 bits and height in the low 16 bits. Retrieving the components requires bit shifting and masking. Another usage is as a naming label for a function parameter or a constant that represents a rectangle’s size.

This concept is more about coding convention than a specific data type. When used, it often appears in graphics, GUI, or imaging code where dimensions must be passed efficiently or stored compactly. Potential drawbacks include reduced readability and increased risk of invalid values if constraints on the bit widths are not enforced. It may also complicate maintenance as the meaning of the packed value depends on the surrounding code.

Alternatives include using explicit width and height fields in a struct or class, or employing standard size types such as a two-element pair, a size class, or a dedicated rectangle type. See also bit packing, rectangles, and dimension representations.
