#include "ltwrappr.h"

static L_UINT16 LICCProfile::DoubleToU8Fixed8Number(dNumber)

L_DOUBLE dNumber;

/* double value */

Converts a fractional value number into a 1-byte fixed, 1-byte fraction format.

Parameter

Description

dNumber

A double fractional value to be converted.

Returns

A 2-bytes (1-byte fixed, 1-byte fraction) value that represents the value passed to the function.

Comments

This function is used for ICC profiles purposes. The returned value must be cast into a L_IccU8Fixed8Number type.

This value consists of 2-bytes. 1-byte contains the fixed part of the number, and 1-byte contains the fractional part of the number.
