Hi, I'm currenlty trying to add more frontend configurable options to the Plustek backend and have some problems with xsane now. There's a value whose range is from -1..63. At the default state, when starting xsane, it is properly displayed: -1. When changing once to i.e. 6 and changing it back to -1, xsane stores it as 0 and also displays it after the next startup as 0.. Bug or feature? What is wrong. The type of this option is SANE_TYPE_INT, the contraint_type is SANE_CONTRAINT_RANGE... The configfile of xsane shows, that this value is stored as 0 and not as -1...
Any ideas? Gerhard
