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.
