C2-2040(HS)-GigE Camera Hardware Reference Manual Rev. 1.8 • 49
Furthermore, when ChunkMode is enabled, the camera sends the full payload, even if the
ChunkImage or ChunkAqInfo blocks contain partially valid data. The number of valid ChunkImage
rows and ChunkAqInfo blocks can be read from ChunkImageInfo.
For example, when in Start/Stop mode with instant frame transmission, the camera stops the frame
acquisition as soon as the stop trigger occurs and transfers the complete contents of internal image
buffer. Using the ChunkImageInfo data block, it is possible to detect how many image rows and
ChunkAqInfo blocks are valid in the payload buffer.
The tag of ChunkData has big endian byte order. The data of ChunkData has little endian byte order.
An endian converter for ChunkData is not supported.
