Creating an unpicker

SEAM_UNPICKER *seamstressNewUnpicker(int actualwidth, int actualheight,int direction,int energyfunc,int dynamicenergy,int *error);

Creates a new Unpicker object.

actualwidth

The width of the image you will be carving.

actualheight

The height of the image you will be carving.

direction

The direction seams will be carved in. Zero indicates only vertical seams will be removed, one indicates only horizontal seams will be removed.

energyfunc

Reserved for future development. This should always be zero at present.

dynamicenergy

If nonzero then the energy will be recomputed after each seam is removed. See Section 3 for details.

error

Pointer to an integer in which an error code will be deposited, or NULL if no error code is desired.

The result, if successful, is a pointer to a new Unpicker object ready to be initialised with the image data. If unsuccessful, NULL will be returned, along with an appropriate error code if error is not NULL.
