Chunk Data Control

Chunk Data allows you the ability to send additional information with the image data. This can be helpful when debugging issues or looking at what settings have been applied to the acquired image.

Use ChunkModeActive to enable chunk data for images.

The following information is available as chunk data:

Image - enabled by default and cannot be disabled.

Image CRC - enabled by default and cannot be disabled.

FrameID

OffsetX

OffsetY

Width

Height

Exposure Time

Gain

Black Level

Pixel Format

ImageTimestamp

Sequencer Set Active

Use ChunkSelector to select a chunk then use ChunkEnable to enable or disable it. Image and ImageCRC cannot be disabled.

Once acquisition has started Chunk data can not be altered. To enable or disable chunks acquisition must be stopped.
