WPD_EXPOSURE_METERING_MODES enumeration

The WPD_EXPOSURE_METERING_MODES enumeration type describes the metering mode to use when estimating exposure for still image capture by a device.

Syntax

typedef enum WPD_EXPOSURE_METERING_MODES { 
  WPD_EXPOSURE_METERING_MODE_UNDEFINED                = 0,
  WPD_EXPOSURE_METERING_MODE_AVERAGE                  = 1,
  WPD_EXPOSURE_METERING_MODE_CENTER_WEIGHTED_AVERAGE  = 2,
  WPD_EXPOSURE_METERING_MODE_MULTI_SPOT               = 3,
  WPD_EXPOSURE_METERING_MODE_CENTER_SPOT              = 4
} ;

Constants

WPD_EXPOSURE_METERING_MODE_UNDEFINED

The metering mode is undefined.

WPD_EXPOSURE_METERING_MODE_AVERAGE

Use averaged exposure across the full image.

WPD_EXPOSURE_METERING_MODE_CENTER_WEIGHTED_AVERAGE

Use an averaged exposure, with the center of the image given more weight.

WPD_EXPOSURE_METERING_MODE_MULTI_SPOT

Use a multi-spot averaging technique.

WPD_EXPOSURE_METERING_MODE_CENTER_SPOT

Use a center-spot averaging technique.

Remarks

Indicates the metering mode of the device. This enumeration is used by the WPD_STILL_IMAGE_EXPOSURE_METERING_MODE property.
