The IG_ISIS_drv_area_dialog function displays a predefined dialog box that allows the user to set scanning area. This is the same dialog that appears when the user clicks the Area button in the Scanner Settings dialog box.
Use this function to display the Area dialog box, allowing the user to set the area to scan. Changing the settings in the Area dialog box modifies the values of IG_ISIS_TAG_IMAGEWIDTH, IG_ISIS_TAG_IMAGELENGTH, IG_ISIS_TAG_XPOSITION, and IG_ISIS_TAG_YPOSITION when the user click the OK button.
Note that the Units setting of this dialog is saved in SETSCAN.INI.
