Hello,
We have implemented a 2D image viewer using JOGL to display large medical images. It allows the user to smoothly pan, zoom the image. Now we want to display the overview of this viewer which will display the entire image in a small viewport (preferably in the bottom right corner of the viewer) with a rectangle displaying area which is presently visible in the viewer.
Are there any existing options from JOGL/OpenGL to achieve this?
If not, can someone give us directions to implement the overview?
Thanks a lot for your help,
Amey.
