説明
mapbox-gl-js version: v0.54.0-beta.1
browser: any
Steps to Trigger Behavior
- create a symbol layer with icon-pitch-alignment set to "map"
- do not rotate or pitch the map
Expected Behavior
Icon should be rendered with NEAREST interpolation
Actual Behavior
Icon is rendered with LINEAR interpolation
Hint: there is a condition in draw_symbol.js:197
pitchWithMap || tr.pitch !== 0
I think it should be just
tr.pitch !== 0
because when icon-pitch-alignment is set to "map", and neither the icon nor the map is rotated, NEAREST should be used. (same as "viewport" alignment)
