Description

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.

Return value

The return value is the address of the newly created LqrCarver object, or NULL in case of failure (insufficient memory).
