We can scan images from camera with Zxing.Net but are there any solution to scanning existent images (like in library) ?
ZXing can read existent images, its Decode
method takes WritableBitmap
as a parameter. So you can get the image from user library with PhotoChooserTask, get WritableBitmap and read it.
Using ZXing is demonstrated here: http://developer.nokia.com/community/wiki/Generating_and_scanning_barcodes_using_ZXing_on_Windows_Phone
_barcodeReader.Decode(_previewBuffer);
_previewBuffer in this case is WritableBitmap
