... for the feedback. A majority there for the "Spline" interpolation. But not so fast. To illustrate the minefield I'm in, if the upscaling is increased it's not so clear-cut. Going up to 720x720 pixels per tile instead of 512x512, the preference maybe swaps to the less intense "Triangle" interpolation (3. below), and "Spline" (4.) is a bit too fuzzy. To confuse the issue further I swapped to the "bright night" colour scheme for the template: 2_250612_120000000.png Zooming out to the more usual browser size, the differences are not so obvious. But we don't do track design at this level: 2_250612_120000001.png We could go higher than 720x720, but memory usage increases dramatically, and screen response speed suffers. Maps can easily have 100 tiles or more. I can also have a fresh think about the low-contrast functions. Maybe with the more intense interpolations it would actually be better to increase the contrast, for a cleaner background? It seems clear that it's worth doing something to ...
