class SpatialAnnotationTrackingOptions.Builder

Summary

Public constructors
`Builder( imageBuffer: ByteBuffer, imageSize: IntSize2d, timestampNanos: Long )`

Public functions
`SpatialAnnotationTrackingOptions`	`build()` Builds a new `SpatialAnnotationTrackingOptions` instance.
`SpatialAnnotationTrackingOptions.Builder`	`setAlignment(alignment: SpatialAnnotationQuadAlignment)` Sets the physical alignment behavior of the resulting 3D quad.
`SpatialAnnotationTrackingOptions.Builder`	`setFormat(format: SpatialAnnotationImageFormat)` Sets the pixel format encoding.
`SpatialAnnotationTrackingOptions.Builder`	`setImageBuffer(imageBuffer: ByteBuffer)` Sets the raw image byte buffer from the camera frame.
`SpatialAnnotationTrackingOptions.Builder`	`setImageSize(imageSize: IntSize2d)` Sets the 2D pixel dimensions of the image buffer.
`SpatialAnnotationTrackingOptions.Builder`	`setQuads(quads: Map<SpatialAnnotationId, Quad>)` Sets the bounding quadrilaterals mapped to their unique tracking IDs.
`SpatialAnnotationTrackingOptions.Builder`	`setRowStride(rowStride: Int)` Sets the row stride (bytes per row) of the image buffer.
`SpatialAnnotationTrackingOptions.Builder`	`setTimestampNanos(timestampNanos: Long)` Sets the system timestamp in nanoseconds correlating to the camera frame, using the `System.nanoTime` clock base.

Builder(
    imageBuffer: ByteBuffer,
    imageSize: IntSize2d,
    timestampNanos: Long
)

Parameters
`imageBuffer: ByteBuffer`	the raw image byte buffer from the camera frame
`imageSize: IntSize2d`	the 2D pixel dimensions of the image buffer
`timestampNanos: Long`	the system timestamp in nanoseconds correlating to the camera frame, using the `System.nanoTime` clock base

fun build(): SpatialAnnotationTrackingOptions

Throws
`IllegalStateException`	if required fields were not explicitly set

fun setImageSize(imageSize: IntSize2d): SpatialAnnotationTrackingOptions.Builder

Sets the 2D pixel dimensions of the image buffer.

fun setQuads(quads: Map<SpatialAnnotationId, Quad>): SpatialAnnotationTrackingOptions.Builder

Sets the bounding quadrilaterals mapped to their unique tracking IDs.

fun setRowStride(rowStride: Int): SpatialAnnotationTrackingOptions.Builder

Sets the row stride (bytes per row) of the image buffer.

fun setTimestampNanos(timestampNanos: Long): SpatialAnnotationTrackingOptions.Builder

Sets the system timestamp in nanoseconds correlating to the camera frame, using the System.nanoTime clock base.
