esri / heatmap-layer-js Goto Github PK

I've gotten heatmap working great in chrome, but IE has some weird artifacts showing up when I zoom or pan. I appears that the edge of the image is repeated just beyond the edge of the extent.

Any ideas what's causing this?

Hi,
I don't know how to describe this problem， the first load is no problem，but when i zoom in the map，the heatmap will show something wrong like this:

looking for it!

So, in total this code is licensed under the following licenses, contradicting the Readme.md text:

Hello, guys
Your product is very good and useful. I've spend little time on investigation, so thank you for a clear example.
I use your lib in my web project, to show heat on an arcgis map. It'd worked fine, but after a year of usage I faced with next error:

This error occured after I've updated my FF to 32.0.3 version. But script works without errors on the previous version of FF.
Could the heatmap libs conflict with new version of FF?
I'm looking forward to your reply. Thanks!

Uncaught Error: declare HeatmapLayer: mixin #0 is unknown. Did you use dojo.require to pull it in?

I found if I modified heatmap-arcgis.js and added required "esri/layers/DynamicMapServiceLayer" that I no longer got the error.
I didn't seem to have any issue with ie or firefox just in chrome.

Let me know if you need more information on it.

Thanks
Jim

such as

<img id="map_heatLayer_1463388826775" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgA.. />
