camera_region_t

This structure is used to identify a subset of pixels in an image.

Synopsis:

#include <camera/camera_api.h>

typedef struct  {
    uint32_t left ;
    uint32_t top ;
    uint32_t width ;
    uint32_t height ;
    uint32_t extra ;
}camera_region_t;

Since:

BlackBerry 10.0.0

Data:

uint32_t left: The left coordinate of the region.; A value of 0 refers to the leftmost column of the image.

uint32_t top: The top coordinate of the region.; A value of 0 refers to the topmost column of the image.

uint32_t width: The width of the region in pixels.

uint32_t height: The height of the region in pixels.

uint32_t extra: An additional application-dependent value that can be used to convey extra information about a region.; Typically, this extra information may be a weighting, ranking, or other application-specific value to apply when defining a set of regions.

Library:

libcamapi (For the qcc command, use the -l camapi option to link against this library)

Description:

Regions are used to report focus lock positions and to configure region-dependent focus, exposure, and white balance operations.
