Hi list, Using the activex importer, I've imported the WIA wiaaut.dll on my Windows 7 system and mostly got WIA scanning (using a flatbed scanner in my case) to work. Thanks to Marco for helping me get this far. The code selects the first scanner, scans while showing the progress dialog and saves the result as a file. What doesn't work: Scanning the entire surface; only part of the image is scanned right now. Fairly essential requirement I'd say ;) Setting the driver to black and white works, but I can't seem to request both black and white and maximum quality: InVar:=wiaCurrentIntent; //what type of image we want to sacn //todo: this won't work gives invalid parameter!! //InVar2:=(WIA_INTENT_IMAGE_TYPE_TEXT or WIA_INTENT_MAXIMIZE_QUALITY); // black & white; good quality for given resolution InVar2:=WIA_INTENT_IMAGE_TYPE_TEXT; SetScannerProperty(Invar,Invar2); Source code: https://bitbucket.org/reiniero/papertiger/src wiademo.lpr and associated units Demo project source also downloadable via the download page. Anyway, suggestions, critique etc welcome as always,
I'm guessing this will not work on Linux, right ? ;-) Michael. -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
