lqr_carver_new, lqr_carver_new_ext — the LqrCarver
object constructors
#include <lqr.h>
LqrCarver* lqr_carver_new( | guchar* buffer, |
gint width, | |
gint height, | |
gint channels) ; |
LqrCarver* lqr_carver_new_ext( | void* buffer, |
gint width, | |
gint height, | |
gint channels, | |
LqrColDepth colour_depth) ; |
The functions lqr_carver_new
and
lqr_carver_new_ext
create a new
LqrCarver
object from an image of size width
* height
with channels
colour channels.
The image must be stored in
buffer
as a plain array of unsigned chars
(for lqr_carver_new
) or the appropriate
type cast to void (for lqr_carver_new_ext
),
ordered by row, then by column, then by colour channel.
In the extended constructor lqr_carver_new_ext
, the additional
parameter colour_depth
is required to specify the colour depth
of the buffer (see LqrColDepth(3) for more information).
After calling the function, the buffer will be owned by the LqrCarver
object and
must not be accessed any more.
