Synopsis:

int camera_meta_get_rgby_histogram_values(const camera_metadata_t metadata,                 
                                          camera_meta_histogram_t *red,                 
                                          camera_meta_histogram_t *green,                 
                                          camera_meta_histogram_t *blue,                 
                                          camera_meta_histogram_t *luma)

Since:

BlackBerry 10.2.0

Arguments:

metadata

The metadata of type CAMERA_METAFORMAT_HISTOGRAM_RGBY supplied to the user-defined consumer function by camera_meta_iterate_metadata().

red

A pointer to a camera_meta_histogram_t structure that will be filled with the red histogram data.

green

A pointer to a camera_meta_histogram_t structure that will be filled with the green histogram data.

blue

A pointer to a camera_meta_histogram_t structure that will be filled with the blue histogram data.

luma

A pointer to a camera_meta_histogram_t structure that will be filled with the luma histogram data.

Library:

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

Description:

Use this function to extract RGBY histograms from the provided metadata.

Returns:

CAMERA_EOK when the function successfully completes, otherwise another camera_error_t value that provides the reason that the call failed.
