LQRCOLDEPTH(3) | LqR library API reference | LQRCOLDEPTH(3) |
NAME¶
LqrColDepth - carver objects colour depth specificationDESCRIPTION¶
The default LqrCarver object constructor lqr_carver_new uses a colour depth of 8 bits per channel, and therefore its input must be an array of unsigned chars. However, the LqrCarver objects can handle images of grater colour depth, if they are created with the lqr_carver_new_ext constructor. The possible colour depths are specified through variables of type LqrColDepth, which is an enum type; its possible values, and the type of the input buffer associated with them, are: LQR_COLDEPTH_8Iuse type guchar (8 bit unsigned
integers) - the default
LQR_COLDEPTH_16I
use type guint16 (16 bit unsigned
integers)
LQR_COLDEPTH_32F
use type gfloat (32 bit floating
point)
LQR_COLDEPTH_64F
use type gdouble (64 bit floating
point)
These values are also relevant when reading out a LqrCarver object with the
functions lqr_carver_scan_ext or lqr_carver_scan_line_ext, since
the readout buffer must be cast to the appropriate type to be actually read.
The colour depth of an LqrCarver object can be obtained with the function
lqr_carver_get_col_depth.
