Is it possible to have the documentation of the .ugm format to create an online viewer/player?

I can give it a try and develop the viewer over here. I think is an amazing and space saving format that could be used more widely.

That's very interesting suggestion!
But I forgot my .ugm data format because it was 19 years ago...

Probably the head of file is total information such as number of point, width of line and else. After that the position data of all points.

I made some progress but still crashing with the tool handling, do the coordinates change depending on the tool? like freehand uses delta coordinates for the strokes as they are in order whereas the ellipse/rectangle uses 5 points and absolute coordinates?

No. What you draw doesn't change data format. It's just group of points when how you drew.

Every point has coordinates(x,y) , flag and temporary 2bytes data. The flag is to judge start point , middle or end point.
