This code snippet declares a vector called "data" of type "RoiData". It also declares a new object called "newData" of type "RoiData".

The variables Roi_Channel, Roi_Content, roiStyle, roiPosition_x, and roiPosition_y are assumed to be previously defined.

The code then assigns values to the member variables of newData using the provided variables. Specifically:
- newData.Roi_Channel is assigned the value of Roi_Channel
- newData.Roi_Content is assigned the value of Roi_Content
- newData.roiStyle is assigned the value of roiStyle
- newData.roiPosition_x is assigned the value of roiPosition_x
- newData.roiPosition_y is assigned the value of roiPosition_y

After this assignment, you can add this newly created object to the vector data using push_back or any other appropriate method.
