Fix Filter to geotiff on load, also cannot filter interpolated

[navilaufm]

Hi, I see how the filter implementation https://ihcantabria.github.io/Leaflet.CanvasLayer.Field/example_ScalarField_Filter.html to filter the field, the behavior for dynamic filter is great, but I don't quite well understand how this works if I want to fix a filter range or condition when adding the CanvasLayer to the map ? (before using the dynamic control)

Can you point me how is this done?

Also, I could not make the dynamic filter work with an interpolated Layer, is this the right behavior of the plugin ?

thanks for any guidance.
