Added in 1.4.0-alpha10
val cropRectBottom: Int

Bottom offset of the cropRect in pixels

cropRectLeft

Added in 1.4.0-alpha10
val cropRectLeft: Int

Left offset of the cropRect in pixels

cropRectRight

Added in 1.4.0-alpha10
val cropRectRight: Int

Right offset of the cropRect in pixels

isSourceMirroredHorizontally

Added in 1.4.0-alpha10
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-alpha10
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-alpha10
val sourceRotation: Int

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