7.23.4 Chunk Mode Active
When Chunk Mode Active is enabled, the camera is in a state where it can generate and append
chunk data to image data and transmit them to the computer. This is only done for the chunk
features that were previously selected and prepared using the Chunk Selector and Chunk Enable
parameters (see Section 7.23.2 on page 338).
Note: Using only the Chunk Selector and Chunk Enable parameters is not sufficient for generating
and appending chunk data. To accomplish this, Chunk Mode Active must also be enabled. Disabling
Chunk Mode Active prevents chunk data from being appended to image data.
1. Set the Chunk Mode Active parameter to true.
You can set the Chunk Mode Active parameter value from within your application software by using
the Basler pylon API. The following code snippet illustrates using the API to set the parameter
value:
camera.ChunkModeActive.SetValue(true);
Also note that when you enable ChunkModeActive, the PayloadType for the camera changes from
"Pylon::PayloadType_Image" to "Pylon::PayloadType_ChunkData".
For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
Image data are counted as chunk 1 (for more details, see Section 7.23.5 on
page 348). Despite this, image data (i.e. the data for chunk 1) can be obtained
even when Chunk Mode Active is disabled.
