Question

May I know how to determine the output of Bing map static image? Previously it used to be in png but now it is in jpeg. May I know how to revert back to png format?

Example: Display the image with the link below:

http://dev.virtualearth.net/REST/V1/Imagery/Map/Road/space%20needle,seattle?mapLayer=TrafficFlow&mapVersion=v1&key=BingKey

The image is in jpeg. How to make it to png? Thanks.

I don’t think you can request the image in a different format.

From http://msdn.microsoft.com/en-us/library/ff701724.aspx :

This URL returns an image in one of
the following formats:

• PNG (image/png)
• JPEG (image/jpeg)
• GIF (image/gif)

You cannot specify the output format
for the map image. The image type is
chosen based on parameters such as
imagerySet.

If you really want a PNG, you could make the request from a server-side script and then construct a PNG file programmatically before serving that back to the client (using PHP’s imagepng function, for example)
