SVG support on ImageLayer?

[Philip2809]

User Story & Rationale

As someone making indoor features with big buildings PNG floormaps can be really big and when using PNGs with sizes over 12k pixels the map comes to a halt. To fix this, the floormaps are in SVG format, could the map be made to support SVGs in the imageLayer?

Impact

This be benefit the users that need the ability to zoom in on a big image, on an SVG you could zoom in as much as you want, but on a PNG the image would start to become pixelated.

The image source is converting the image to non vector image in order to pass it to the GPU.
Supporting SVG in webgl seems like a huge lift and I'm not sure it's worth the effort.
I would advise to create a raster source, so that this image can be seen well in multiple zoom.
I think that the image source can play a role in converting an image to tiles and show the relevant tile in the relevant zoom, but that isn't exactly the same as SVG...
Another approach you can use is simply use an HTML element that shows a SVG on the map.

In any case, if you have a use case worth investing time and resources you are more than welcome to push it forward!

I understand, thanks for answer.
Do you mean we have an SVG and render it to raster tiles with different zooms?
Can you get an HTML layer on the map with features there is today, if not I feel this can be very difficult to do, especially if you allow pitch, maybe this can be done with rotate3d and translate3d?

[HarelM]

Not sure about pitch, html popup can be placed in a position and this position is translated when the map moves.
You might need other features to make it pitch and stretch, not sure.

Yes, I think it's the "easiest" solution.
