This library was create to use cameras with not default properties, like Google Glass, some Nexus, Smartwatches, etc
This is a modify version of ZXING and version of user IceFair333 (https://github.com/zxing/zxing)
I create this version because the image of camera in Google Glass with original Zxing/Icefair333 version show scrambled. (Tested on XE16 and XE17)
Simple Sample to work with Google Glass:
Dim zx As ZXingGlass
zx.EnableJavaLog = True
zx.CameraAngle = 0
zx.useFrontCam = False
zx.PreviewWidth = 640
zx.PreviewHeight = 360
zx.FPSMin = 30000
zx.FPSMax = 30000
zx.BeginScan("myzx")
Properties you can use to scan and create the barcodes
* Property: CameraAngle()
* Description: Set rotation to "n" degrees in camera
* Sample:
* Dim zx As ZXing
* zx.GlassCameraAngle = 90
* Property: useFrontCam()
* Description: Force use the Frontal Camera
* Sample:
* Dim zx As ZXing
* zx.useFrontCam = True
* Property: PreviewWidth()
* Description: Set Width of preview image
* Obs: Use EnableJavaLog = True to view all values of your camera
* Sample:
* Dim zx As ZXing
* zx.PreviewWidth = 640
* zx.PreviewWidth = 480
* Property: PreviewHeight()
* Description: Set Height of preview image
* Obs: Use EnableJavaLog = True to view all values of your camera
* Sample:
* Dim zx As ZXing
* zx.PreviewWidth = 640
* zx.PreviewWidth = 480
* Property: FPSMin()
* Description: Set Min Valiue to Frames Per Second of your camera
* Obs: Use EnableJavaLog = True to view all values of your camera
* Sample:
* Dim zx As ZXing
* zx.FPSMin = 10000
* zx.FPSMax = 30000
* Property: FPSMax()
* Description: Set Max Valiue to Frames Per Second of your camera
* Obs: Use EnableJavaLog = True to view all values of your camera
* Sample:
* Dim zx As ZXing
* zx.FPSMin = 10000
* zx.FPSMax = 30000
* Property: EnableJavaLog()
* Description: Enable Log from Java Code to view more information about your camera
* Sample:
* Dim zx As ZXing
* zx.EnableJavaLog = True
* Property: Version()
* Description: Show the version of this library
* Sample:
* Dim zx As ZXing
* Log(zx.Version)
* Property: About()
* Description: Show the library about
* Sample:
* Dim zx As ZXing
* Log(zx.About)
* Method: BeginScan
* Sample:
* Dim zx As ZXing
* zx.BeginScan("myzx") 'where "myzx" is the name of event is fired where result is coming. like: Sub myzx_result(atype As String,Values As String)
*
* please handle the event
* add this to manifest:<activity android:name="ice.zxing.CaptureActivity"
* android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden"
* android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
* android:windowSoftInputMode="stateAlwaysHidden"></activity>
* Property: Create2DCode()
* Description: Create a Barcode based on your text
* Sample:
* Dim zx As ZXing
* ImageView1.Bitmap = zx.Create2DCode("Alberto Iglesias")
And you case use the library to get the internal properties of camera, like this (to enable this, use the EnableJavaLog = True and look your log):
