Search for images with transparent background

[Yukai Hong]

Using google's custom search for images or deprecated image search API, is there a way to restrict results to return only images with transparent background?

Thanks.

For the deprecated Image Search API, you can specify the (undocumented, as far as I can tell) parameter imgc=trans 

For exampe:

https://ajax.googleapis.com/ajax/services/search/images?q=queen&v=1.0&imgc=trans

However, since this is going away very, very soon it seems, I'd really love a way to do this with the CSE API. Does anyone know? Is there a way to suggest it for the product roadmap?

I really searching for an answer but I need it to be with CSE API or Bing Search API

do you have any suggestion for that

Thanks in advanced.
