Method Detail

supports

public boolean supports(Control control)

Shorthand for getSupported*().contains(value).

Parameters:

control - value to check

Returns:

whether it's supported

supports

public boolean supports(GestureAction action)

Shorthand for other methods in this class, e.g. supports(GestureAction.ZOOM) == isZoomSupported().

Parameters:

action - value to be checked

Returns:

whether it's supported

getSupportedControls

public <T extends Control> java.util.Collection<T> getSupportedControls(@NonNull
                                                                        java.lang.Class<T> controlClass)

getSupportedPictureSizes

@NonNull
public java.util.Set<Size> getSupportedPictureSizes()

Set of supported picture sizes for the currently opened camera.

Returns:

a set of supported values.

getSupportedPictureAspectRatios

@NonNull
public java.util.Set<AspectRatio> getSupportedPictureAspectRatios()

Set of supported picture aspect ratios for the currently opened camera.

Returns:

a set of supported values.

getSupportedFacing

@NonNull
public java.util.Set<Facing> getSupportedFacing()

Set of supported facing values.

Returns:

a set of supported values.

See Also:

Facing.BACK, Facing.FRONT

getSupportedFlash

@NonNull
public java.util.Set<Flash> getSupportedFlash()

Set of supported flash values.

Returns:

a set of supported values.

See Also:

Flash.AUTO, Flash.OFF, Flash.ON, Flash.TORCH

getSupportedWhiteBalance

@NonNull
public java.util.Set<WhiteBalance> getSupportedWhiteBalance()

Set of supported white balance values.

Returns:

a set of supported values.

See Also:

WhiteBalance.AUTO, WhiteBalance.INCANDESCENT, WhiteBalance.FLUORESCENT, WhiteBalance.DAYLIGHT, WhiteBalance.CLOUDY

getSupportedHdr

@NonNull
public java.util.Set<Hdr> getSupportedHdr()

Set of supported hdr values.

Returns:

a set of supported values.

See Also:

Hdr.OFF, Hdr.ON

isZoomSupported

public boolean isZoomSupported()

Whether zoom is supported. If this is false, pinch-to-zoom will not work and CameraView.setZoom(float) will have no effect.

Returns:

whether zoom is supported.

isVideoSnapshotSupported

public boolean isVideoSnapshotSupported()

Whether video snapshots are supported. If this is false, taking pictures while recording a video will have no effect.

Returns:

whether video snapshot is supported.

isAutoFocusSupported

public boolean isAutoFocusSupported()

Whether auto focus is supported. This means you can map gestures to GestureAction.FOCUS or GestureAction.FOCUS_WITH_MARKER and focus will be changed on tap.

Returns:

whether auto focus is supported.

isExposureCorrectionSupported

public boolean isExposureCorrectionSupported()

Whether exposure correction is supported. If this is false, calling CameraView.setExposureCorrection(float) has no effect.

Returns:

whether exposure correction is supported.

See Also:

getExposureCorrectionMinValue(), getExposureCorrectionMaxValue()

getExposureCorrectionMinValue

public float getExposureCorrectionMinValue()

The minimum value of negative exposure correction, in EV stops. This is presumably negative or 0 if not supported.

Returns:

min EV value

getExposureCorrectionMaxValue

public float getExposureCorrectionMaxValue()

The maximum value of positive exposure correction, in EV stops. This is presumably positive or 0 if not supported.

Returns:

max EV value
