Suppose you have a series of RasterLayers in your WinformsMap that you increase in size and resolution as you go up in ZoomLevel. The first raster image of the world would be relatively low resolution, and as you zoom farther in, you would likely split up higher resolution images, say, into 8 tiles to cover the world, visibile to higher zoom levels.
When you first load the map and load all these layers with a CurrentExtent of the whole world, the memory usage is low. Then, when you zoom into a CurrentExtent that has a zoom level that includes the 8 tiles, the memory use goes up, as we would expect.
However, when you zoom back out, the memory use does not go down, even after some time and map refreshes.
Is there a way to change this behavior? Thanks!
