Hi there,
I am migrating my code from ImageCaptureMBS to the Leopard Image Kit plugin. I
have it set up to take a picture, and when the item is added to the camera to
download the image to the computer. It works for the first 2 photos, but on the
3rd, it crashes (in my app with a Signal 11). It appears the camera object
(ICCameraDeviceMBS) is becoming invalid in some way.
I can reproduce the crash with the Camera Browser example.
- If you click on the camera that appears on the left in the Cameras listbox.
- Once cataloging of the camera is complete and you can see the images listed
select an image and click on Download.
- Repeat this 2 more times (with different images).
- Now click on Take Picture button, the application will crash with the log
shown below.
Am I missing something or is the camera device being released in some way ?
Thanks for you help,
Andy
