How use with Open Layers 6

[TuxGit]

Hi! Thx for this project to test geotiffjs with ol.

I try to run code from github and its ok! (ol v4)
But then I upgrade ol to latest version (v6) my tiff image displayed wrong. There are no errors in the console. (yes, i renamed imports like import Tile from 'ol/tile'; -> import Tile from 'ol/Tile';)

I'm not as well versed in the depths ol. Why did it break? can someone tell me how to fix it)

open layers 4.6.5

open layers 6.1.1

Hey @TuxGit

Thanks for your interest in geotiff-js/COG-explorer!

To be honest, it is hard to tell, where it is going wrong exactly. We did various quirks to make the rendering run for that version, which apparently do not work for v6 anymore.

I'll have a look and will see whether this can be easily fixed.

It would be really awesome if this work was packaged in a reusable way (such as a ol.source.Cog class). COG are awesome, but unfortunately you seem to be the only one so far who was able to implement them with Openlayers !

(see cogeotiff/www.cogeo.org#36 and openlayers/openlayers#10733)

I don't want to spoil anything, but this is what @IvanSanchez is working on: https://github.com/IvanSanchez/openlayers/tree/webgl-wip

The main issue is that a TIFF does not necessarily mean that it is visual. Otherwise browsers would have had native support ages ago :-)

That's great news !! @IvanSanchez please let me know if I can help (for instance by testing)

@TuxGit
How did you get OpenLayers 6.1.1 to work at all? When I tried OpenLayers 6.4.3, I didn't have access to ol.Tile to do extend class CanvasTile extends Tile so I had to stick with OpenLayers 4.6.5.
