## Syntax

    PgGray (gray_level)

## Arguments

`gray_level`

  A level for gray between 0 - 255 decimal (0x00-0xff hex).

## Returns

A 24-bit color representation of the `gray_level`.

## Description

This function converts a gray level index from 8-bit to 24-bit color. For example, an image may contain 256 shades of gray. To convert those grays to 24-bit color use this function to acquire the 24-bit equivalents.

## Example

        Gamma> BLACK = PgGray(0);
        0x0
        Gamma> WHITE = PgGray(255);
        0xffffff
        Gamma> MEDGRAY = PgGray(128);
        0x808080
        Gamma> WHITE = PgRGB(255,255,255);
        0xffffff
        Gamma> PgGray(0xff) == WHITE;
