WIAPascal is a runtime Package to handle WIA Scanner under Windows. There are no visual components that have to be installed. Just add the package to dependancy/required of your Lazarus/Delphi Application and start using it. The Package was created from scratch by Massimo Magnano since there was nothing written in Pascal about it.
