Flags for IG_ISIS_drv_set_dialog function.
| IG_ISIS_DRV_SET_DLG_BIN | Restrict the scanner settings to binary, effectively preventing the user from choosing grayscale or color modes. |
| IG_ISIS_DRV_SET_DLG_AREA | Show the Area button on the dialog box. When the user clicks the Area button, the Area dialog box appears. When not set, the Area button is not visible. |
| IG_ISIS_DRV_SET_DLG_RETURN | When set, if the user clicks Cancel, IG_ISIS_drv_set_dialog returns IG_ISIS_ERR_CANCEL. If the user clicks OK, it returns IG_ISIS_SUCCESS. If this flag is not set, IG_ISIS_drv_set_dialog always returns IG_ISIS_SUCCESS. |
| IG_ISIS_DRV_SET_DLG_AREAPREVIEW | When set, if the user clicks on the Area button, the dialog displayed will include a preview box where the user can set the scan area through mouse actions. The preview box may display an image if a callback function has been set with IG_ISIS_area_dialog_CB_register, otherwise it will be gray. Using this flag automatically sets the IG_ISIS_DRV_SET_DIALOG_AREA flag as well. |
