Enumeration MeasureUnit

MeasureUnit specifies how a numeric value should be interpreted relative to a reference dimension. It is used wherever a numeric parameter (e.g., spacing, ROI coordinates) can be expressed either as an absolute pixel count or as a proportion of a reference size.

typedef enum MeasureUnit
{
    /** The value is an absolute pixel count. */
    MU_PIXEL      = 0,
    /** The value is a percentage of the reference dimension (e.g. 25 = 25%). */
    MU_PERCENTAGE = 1
} MeasureUnit;
