How to display multi_part data

[jpl-c]

Hi,
This is more a question rather than an actual bug report.
I am using a Keyence Linescan camera that creates several images from a single capture. I am trying to display several of these images at once in the GUI but with no success. It seems to me this should be possible as I can see in the gui code that different gentl payload types are supported (including multi-part which is what I am interested in):

in canvas.py :

class Canvas2D(CanvasBase): _visible_payloads = [ PAYLOADTYPE_INFO_IDS.PAYLOAD_TYPE_IMAGE, PAYLOADTYPE_INFO_IDS.PAYLOAD_TYPE_CHUNK_DATA, PAYLOADTYPE_INFO_IDS.PAYLOAD_TYPE_MULTI_PART, ]

The Camera's proprietary GUI can show multiple images at once so I am assuming it is possible to do so with GenICam and harvester.

I am wondering what it is that I am missing to use this multi-part payload type. I can't seem to find this parameter in the Attribute Controller.
Could this be linked to the genTL producer that I am using and that does not support this?

I am using :

• OS : Windows 10
• Python 3.9.0
• Harvester 1.4.0
• Harvester GUI 1.0.2
• Genicam 1.2.0
• GenTL producer : Matrix-Vision Acquire SDK x64 2.48

Thanks a lot!

Update on my previous issue. The problem was coming from my camera that was not sending a multi-part buffer in the first place. I needed to do new Image Acquirer acquisition without taking a new capture (had to change the MultiCaptureUpdateImage node value to False to do so).

The full explanation can be found in the online documentation to the camera if this can be useful to anyone. It is the Keyence VJ Series System Integration Manual :

I haven't found a way to display the images together in the UI however, but this actually isn't that much of an issue for me anyways.

Cheers,
