Setting Reverse X
You can enable or disable the reverse X feature by setting the ReverseX parameter value. You can
set the 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:
// Enable reverse X
camera.ReverseX.SetValue(true);
You can also use the Basler pylon Viewer application to easily set the parameter.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 43 .
For color cameras, provisions are made ensuring that the effective color filter
alignment will be constant for normal and mirror images.
You can use the ROI feature when using the reverse X feature. Note, however,
that the position of an image ROI relative to the sensor remains the same
regardless of whether or not the reverse X feature is enabled.
As a consequence, an image ROI will display different images depending on
whether or not the reverse X feature is enabled.
Auto function ROIs will behave analogously to image ROIs.
