getCropRectBottom

Added in 1.4.0-alpha08

public final int getCropRectBottom()

Bottom offset of the cropRect in pixels

getCropRectLeft

Added in 1.4.0-alpha08

public final int getCropRectLeft()

Left offset of the cropRect in pixels

getCropRectRight

Added in 1.4.0-alpha08

public final int getCropRectRight()

Right offset of the cropRect in pixels

getCropRectTop

Added in 1.4.0-alpha08

public final int getCropRectTop()

Top offset of the cropRect in pixels

getSourceRotation

Added in 1.4.0-alpha08

public final int getSourceRotation()

Rotation of the source, relative to the device's natural rotation.

hashCode

public int hashCode()

isSourceMirroredHorizontally

Added in 1.4.0-alpha08

public final boolean isSourceMirroredHorizontally()

Indicates whether the source has been mirrored horizontally.

This is common if the source comes from a camera that is front-facing.

It is not common for both isSourceMirroredHorizontally and isSourceMirroredVertically to be set to true. This is equivalent to sourceRotation being rotated by an additional 180 degrees.

isSourceMirroredVertically

Added in 1.4.0-alpha08

public final boolean isSourceMirroredVertically()

Indicates whether the source has been mirrored vertically.

It is not common for a camera source to be mirror vertically, and typically isSourceMirroredHorizontally will be the appropriate property.

It is not common for both isSourceMirroredHorizontally and isSourceMirroredVertically to be set to true. This is equivalent to sourceRotation being rotated by an additional 180 degrees.
