Resampling when zooming out

[howff]

When I zoom out of a high resolution image of a coastline most of the pixels disappear, presumably because it's picking the "nearest" pixel to plot and most of the image pixels are black. Would it be possible for it to use resampling to pick a better colour? Or would that be too slow at redrawing the image?

Not sure how to pick a suitable colour - average, or brightest, or ...?

tuiview uses the overview (or pyramid) layers from the image. You'd have to see you those were generated. Look at either at gdaladdo or rioscalcstats and their options.

ok, thank you, I'll try to change the resampling algorithm used to create the overviews
