A 32-bit quantity that indicates the gamma correction to use on the scan image. The first 16 bits indicate the integral portion of the gamma correction. The last 16 bits indicate the fraction portion in units of 1/65536. An example is gamma correction value of 2.2 will be representedas 0x00023333 (2 & 13107/65536ths)). The 4-pack products (HP Laserjet 3200, HP Laserjet 1220, HP Laserjet 2200 & HP Laserjet 1200) software will set the gamma correction to be applied on the scan data. IPE SW will request a value of 1.0, which indicates no gamma correction. TWAIN software will request a value of 2.2 for grayscale scans and 2.9 for color scans. The device pos will indicate any deviation from the above description. Additional information: Indicates the gamma correction to use on the scan image. The first 16 bits indicate the integral portion of the gamma correction. The last 16 bits indicate the fraction portion and in units of 1/65536. An example is gamma correction value of 2.2 will be represented as 0x00023333 (2 & 13107/65536ths).
