Hi, I am using the imagemosaic-jdbc plugin, with some large image files which are being displayed in a JMapPane. I have noticed that when repainting is required (due to resizing etc) the rendering seems to follow this process:
(I haven't been able to locate this process in the code, so its purely speculation based on experimentation.) 1. Clear dirty area of screen 2. Submit request to DB in a separate thread 3. When request is returned, paint the cleared area of screen. This means that when the request takes a non-trivial amount of time, the map pane changes to white for a period and then back to the image. IMO, it would be better to not clear the dirty area until the new image is ready to be painted, so there would not be a white period. Is this possible to implement? Is my guessing of how the rendering is done correct? Could someone point me to the appropriate code so I can at least implement this for my own purposes? Thanks very much for your help, it is much appreciated.
