Description

While improving the Visium HD notebook after https://github.com/scverse/spatialdata-plot/issues/303 has been addressed I have noticed that there must be a problem with interpolations of images when the target canvas is small, because I can't replicate the plot shown in figure with the commented code (when I tried it shows everything black; if I put a large figsize e.g. (30, 30), I start seeing some white pixels).

To reproduce please run the Visium HD notebook.

Research direction

Run the Visium HD notebook and inspect the commented plotting code that produces an all-black image at a small target canvas. Compare it with the attached figure and with a large figsize such as (30, 30); done means the interpolation renders the image consistently at the smaller canvas as well.
