Public properties

cropRectBottom

Added in 1.4.0-alpha08

val cropRectBottom: Int

Bottom offset of the cropRect in pixels

cropRectLeft

Added in 1.4.0-alpha08

val cropRectLeft: Int

Left offset of the cropRect in pixels

cropRectRight

Added in 1.4.0-alpha08

val cropRectRight: Int

Right offset of the cropRect in pixels

cropRectTop

Added in 1.4.0-alpha08

val cropRectTop: Int

Top offset of the cropRect in pixels

isSourceMirroredHorizontally

Added in 1.4.0-alpha08

val isSourceMirroredHorizontally: Boolean

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

val isSourceMirroredVertically: Boolean

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.

sourceRotation

Added in 1.4.0-alpha08

val sourceRotation: Int

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