I doubt UNIPEN image format[^] is a regular raster image OpenCV can open. As I understood, it contains a set of points and some metadata. Here is a Java code to read it: https://github.com/aravindc26/UniView/blob/master/src/com/aravindc/UniView/unipen/UnipenReader.java[^], and here is one in c#: UPV – UNIPEN online handwriting recognition database viewer control[^] (with rendering tool too), but I am pretty sure you can find also a c++ reader somewhere. But you still need to render it's content to have it as image.
