Hi, from the standard: "Member size specifies the size of the option value (in bytes). ... SANE_TYPE_INT, SANE_TYPE_FIXED: The size must be a positive integer multiple of the size of a SANE_Word. The option value is a vector of length size/sizeof(SANE_Word)."
The umax backend defines an option "halftone pattern" with size 0. Is this allowed? Furthermore, the umax backend changes the option size later. IMHO, that at least isn't allowed, because only the availablity or value of an option may change. bb Michael
