问题
I'm using Google static maps (documention here) to show shops' locations, and I'm using a custom marker instead of the default.
However, this marker image appears low-resolution on high-resolution mobiles like the iPhone 4.
How do I fix it?
回答1:
Set &markers=scale:2 in conjunction with a @2x marker icon image and the &scale=2 parameter.

In order to avoid the low-resolution dithering, you need to use proportionately larger custom marker images. See the example below, which references a 64x64 pushpin:
