When trying to apply a 64x64px pattern in an extruded LineString, with height 1, it's quite clear that how image pattern is applied as a texture in that axe (z).
With a good pow2 image ratio, we could get easily:
- 1 meter height => image appears once
- 2 meters height => image appears twice
However, it's not clear at all how width ratio is applied.
With a 1 meter width in equator (latitude=0), image is cut (not full width).
With a 1 meter width in latitude 45, image appears more than once for the width.
And with a power2 image, offset bottom-left suits well, otherwise it's "random".
Could we have an explanation on the way pattern is applied on an LineString extrusion ?
My goal is to be able to have my pattern image displayed completely and no more (no repeat, no offset), as a kind of building wall.
This could be very powerful to apply some texture on buildings, or for indoor stuffs...
