Clustering issue since 4.0.25

[mdellanave]

Hi guys,
I found some problem using clustering starting from the release 4.0.25.

I have untouched code built on this example
https://viglino.github.io/ol-ext/examples/animation/map.animatedcluster.html

Using version 4.0.24 I see the circles area with the counter

Since version 4.0.25 the circles do not appears, but it seems they are there because if I click they will expand

any idea?

Which version of ol are you using?
ol >10.3.1 introduce createRenderOptions on style (see #1123)
Maybe you can try ol-ext@4.0.26
It may be a bug on Chart style

Hi @Viglino
I think the issue does not depends on ol version, I tried with 10.3.1 and 10.4.0 with the same result.

About ol-ext, I tried both the 4.0.25 and 4.0.26 versions but I had to rollback to the 4.0.24 to make it works as usual.

Thank you for your support!

[Viglino]

Do you have an online code to test?

[mdellanave]

not right now, sorry

[mdellanave]

I think this could be a base example
https://codesandbox.io/p/devbox/simple-forked-jqdn4p?workspaceId=ws_JP1zBczYgG5PvHLMG4yFpf

and if I change to 4.0.24

[Viglino]

I can't access the devbox

Devbox not found
It's likely that the Devbox you're trying to access doesn't exist or you don't have the required permissions to access it.

May be related to this: #1041

[mdellanave]

uh! what a strange issue, I'll try to upgrade the upgradable and let you know something more
thank you for your time!

[mdellanave]

I tried updating window to Windows 11, version 24H2, the latest available, but with no luck...
tested with the latest version of chrome (133.0.6943.60) edge and firefox

Seems to be a pixelratio issue #1109
Last commit should fix it.

[mdellanave]

Thank you Jean-Mark, I will try it as soon as the hotfix will be available and then let you know.
have a nice day

You can replace the file in your node_module ol-ext/style/Charte.js to test.
https://github.com/Viglino/ol-ext/blob/master/src/style/Chart.js

[mdellanave]

In my project I'm currenty using the dist ol-ext.js file, so I tried to replace my file with this one https://github.com/Viglino/ol-ext/blob/master/dist/ol-ext.js and seems to works fine.

Does it already contains the fix you mentioned?

thank you again

[Viglino]

You can use the dist js from Github: https://viglino.github.io/ol-ext/dist/ol-ext.js

@Viglino, Thank you for fixing the pixelRatio issue.
However, the chart didn't display correctly with version 4.0.26 installed via npm. I compared it with Chart.js, and it's not the latest version from the master branch. (Master branch one can work well in my project)
Could you please release a new version?

[Viglino]

Just publish ol-ext@4.0.27

[mdellanave]

Thank you @Viglino, I can confirm the fix is ok!
