IDDCX_BITS_PER_COMPONENT enumeration (iddcx.h)

  • Artikel

An IDDCX_BITS_PER_COMPONENT enumeration value identifies the supported or requested number of bits per color component for the dithering support of a target.

Syntax

typedef enum IDDCX_BITS_PER_COMPONENT {
  IDDCX_BITS_PER_COMPONENT_NONE = 0,
  IDDCX_BITS_PER_COMPONENT_6 = 0x1,
  IDDCX_BITS_PER_COMPONENT_8 = 0x2,
  IDDCX_BITS_PER_COMPONENT_10 = 0x4,
  IDDCX_BITS_PER_COMPONENT_12 = 0x8,
  IDDCX_BITS_PER_COMPONENT_14 = 0x10,
  IDDCX_BITS_PER_COMPONENT_16 = 0x20
} ;

Constants

 
IDDCX_BITS_PER_COMPONENT_NONE
Value: 0
A driver can use this flag to indicate no support for a particular wire encoding format; for example, in calls to EVT_IDD_CX_ADAPTER_QUERY_TARGET_INFO or EVT_IDD_CX_MONITOR_QUERY_TARGET_MODES2. When it is used as an input in the driver, for example as part of a call to EVT_IDD_CX_ADAPTER_COMMIT_MODES2, this value is never used.
IDDCX_BITS_PER_COMPONENT_6
Value: 0x1
For driver reporting, indicates support for sending color component values using 6 bits. For driver information, indicates 6 bits per component should be sent to the monitor.
IDDCX_BITS_PER_COMPONENT_8
Value: 0x2
For driver reporting, indicates support for sending color component values using 8 bits. For driver information, indicates 8 bits per component should be sent to the monitor.
IDDCX_BITS_PER_COMPONENT_10
Value: 0x4
For driver reporting, indicates support for sending color component values using 10 bits. For driver information, indicates 10 bits per component should be sent to the monitor.
IDDCX_BITS_PER_COMPONENT_12
Value: 0x8
For driver reporting, indicates support for sending color component values using 12 bits. For driver information, indicates 12 bits per component should be sent to the monitor.
IDDCX_BITS_PER_COMPONENT_14
Value: 0x10
For driver reporting, indicates support for sending color component values using 14 bits. For driver information, indicates 14 bits per component should be sent to the monitor.
IDDCX_BITS_PER_COMPONENT_16
Value: 0x20
For driver reporting, indicates support for sending color component values using 16 bits. For driver information, indicates 16 bits per component should be sent to the monitor.
