Redefine tile coloring rules

Now we have encountered such a problem: I use the “UrlTemplateImageryProvider” interface to load a tile service data. This tile service belongs to a third party and we can’t do anything about it. However, the rendering form of tile data obtained is not what we want, so we want to customize a tile decoding form after obtaining tile data, and re assign RGB values to tiles according to the decoding rules.

I would like to ask you if there is any way to solve this problem.

Just like repainting tiles in openlayer
