microscope.cameras.ximea module

Ximea cameras.

Changing settings flushes the buffer

It is not possible to set some parameters during image acquisition. In such cases, acquisition is stopped (camera is disabled) and the restarted (camera is enabled). However, stopping acquisition discards any image in the camera memory that have not yet been read.

Modifying the following settings require acquisition to be stopped:

• ROIs

• binning

• trigger type (trigger source)

For more details, see the [XiAPI manual](https://www.ximea.com/support/wiki/apis/XiAPI_Manual#Flushing-the-queue).

Hardware trigger

Ximea cameras in the MQ family accept software triggers even if set for hardware triggers (see vendor issues #3`<https://github.com/python-microscope/vendor-issues/issues/3>). However, `XimeaCamera.trigger() checks the trigger type and will raise an exception unless the camera is set for software triggers.
