PhotoOverlay <gx:highResolution> #382

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
This feature would allow high-resolution PhotoOverlays during Google Earth 
navigation.

Currently, Google Earth downsamples a PhotoOverlay image to (what looks to me 
like) a 256x256 pixel texture, then scales that low-res/low-quality texure as 
the viewer approaches. It only uses the full-res image if you suspend 
navigation and use the special zoom & pan PhotoOverlay UI.

Setting <gx:highResolution> to 1 would tell Google Earth to use (up to) the 
maximum supported texture size for the PhotoOverlay during navigation. This 
attribute would default to 0 (disabled) for backwards compatibility.

For example: On my laptop the maximum texture size is 2048x2048, so it could 
easily display full-res images that fill the entire screen at 1:1. In practice, 
most of my geotagged photos in KML are only 640x480 or 1024x768, not even close 
to the texture limit.

Thanks for your consideration.
