dmColorPrecompute - performs any precomputation required.
DMstatus dmColorPrecompute (const DMcolorconverter converter);
The converter upon which the action is to be applied.
DM_COLOR_ERROR_NONE if operation is successful.
DM_COLOR_ERROR_INVALID_CONVERTER if the converter is invalid.
Before dmColorConvert can convert an image, some precomputation is
required. This computation will be performed during the first
dmColorConvert call, or any subsequent dmColorConvert call after a
dmColorSet call has changed the desired transform. If this
precomputation overhead would be more suited to occur elsewhere in the
program (such as outside the main loop), dmColorPrecompute should be
dmColorCreate(3dm) dmColorDestroy(3dm) dmColorConvert(3dm)
