Hi XverhelstX,

is it possible to enhance your Library supporting additional properties: setAutoExposureLock() and getAutoExposureLock()?

http://developer.android.com/refere....Parameters.html#setAutoExposureLock(boolean)

If I'm not mistaken, that's already supported on the CameraEx class.

Steini1980 · Apr 10, 2015

The're many Methods implemented, but I can't find an interface which allows to work with AutoExposureLock.

ExposureCompensation is implemented, but in dependency with android device it's just possible to correct the ExposureCompansation +/-2.
The requirements of my customer is always to take photos with back light (e.g. doors and windows from inside), so it's necessary to have a greater scope to adjust camera settings such as the Exposure.

Steini1980 · Apr 14, 2015

Now I have solved with CameraEx Class, look here:

Hello.
Did anyone try to create flashlignt app for Nexus 5? I tried cam.FlashTorch, then cam.toggleFlashLight functions. Both with no success. Flashlight simply does not turn on, nothing happens. cam.SupportedFlashMode shows "off, auto, on, torch" are avalaible.

I would like to take a 256x256 pixel image and save it as JPG, can this be done, I have read through this and it seems it will save it at the max resolution of the camera?? any examples for this??

Thanks!

B4X:

Sub capture_Click
    Try
        LoadLayoutIntoActivity("camera")
        Dim camera As AdvancedCamera
        camera.initilize(panel1,"camera_event")
        camera.StartPreview
       Catch
        ToastMessageShow("Error", True)
