The XML parameters related to ROI settings are as follows.
XML Parameters
ImageFormatControl
The unit for all parameters in this table is pixel
a: Read only. User cannot change the value
b: Changes and updates according to the Binning settings
c: User configurable parameters for settings ROI
d: User configurable parameters for setting the origin of the ROI
You can change the size of ROI by setting the Width and Height parameters. And also, you can change the
position of the ROI origin by setting the Offset X and Offset Y parameters.
Make sure that the Width + Offset X value is less than the Width Max value, and the Height + Offset Y value is
less than the Height Max value. You must set the size of the ROI first, and then set the Offset values since the
Width and Height parameters are set to its maximum value by default.
The Width parameter must be set to a multiple of 4, and the Height parameter must be set to a value greater
than the minimum Vertical ROI size shown in the
changed and updated depending on the Binning Horizontal and Binning Vertical parameter settings
respectively. And also, the Width, Height, Offset X and Offset Y parameters will be updated depending on the
Binning Horizontal and Binning Vertical parameter settings respectively.
ROI Size updated according to the Binning settings may not be restored to its original value. For example, if you
set the Binning Horizontal parameter to ×3 with 500 Width, the Width parameter will be updated to 166
automatically. Then, if you set the Width parameter to 166 and the Binning Horizontal parameter to ×1, the
Width parameter will be 498 (166 × 3). If you want to restore the Width to its original value, you can set the
Width to 500 manually.
