Hi,
I’m trying to implement a dynamic heatmap. A faster way to update raster overlay image would help me a lot.
I use an array including several points as dataset. Each point has global effect.
The dataset and algorithm basically decide that I can’t use MPC like mentioned in this issue. So I write a class inherited from RasterOverlay to paint the heatmap.
But the raster overlay refreshes much more slowly than I expect, with a moment of disappearance in the progress. The progress of refresh including remove the raster overlay and add a new one. Can we find a easier way like, just change some parameters of the raster overlay and trigger the reloading of image? Or is Raster Overlay designed to have a still, all-its-life image?
Thanks,
