MP_CURVE_TYPE Enumeration
The MP_CURVE_TYPE enumeration defines the curve that a media parameter follows within an envelope segment.
Syntax
typedef enum _MP_CURVE_TYPE {
MP_CURVE_JUMP = 0x0001,
MP_CURVE_LINEAR = 0x0002,
MP_CURVE_SQUARE = 0x0004,
MP_CURVE_INVSQUARE = 0x0008,
MP_CURVE_SINE = 0x0010,
} MP_CURVE_TYPE;
Elements
MP_CURVE_JUMP
No interpolation. Jump to the next point.
MP_CURVE_LINEAR
Linear interpolation.
MP_CURVE_SQUARE
Parabolic curve.
MP_CURVE_INVSQUARE
Inverse square curve.
MP_CURVE_SINE
Sine curve.
Remarks
The following table lists the defined curves and their mathematical equivalents.
| Value | Curve to Fit | Range |
| MP_CURVE_LINEAR | y = x | 0.0 – 1.0 |
| MP_CURVE_SQUARE | y = x2 | 0.0 – 1.0 |
| MP_CURVE_INVSQUARE | y = 1 – x2 | 0.0 – 1.0 |
| MP_CURVE_SINE | y = sin(x) | –π/2 – π/2 |
For Boolean and enumeration parameters, only MP_CURVE_JUMP is valid.
