Rendering Heatmap on ImageView

[orkasan]

Hi, what would be the best practice to render heatmap on top of ImageView with CGPoints (x-y coordinates) instead of CLLocations with longitute-latitude?

[jamesdouble]

Do you mean you want to cover the heat 'layer' on top of an ImageView?

[orkasan]

Yes, that is exactly what I want, what do you think?

[jamesdouble]

You can adjust codes in JDOverlayRender.swift to get the heatmap CGImage.

Or before it become CGImage, get contextlayer and you draw it in your way
