How to know if a texture is compressed?

Hi, I am trying to work on code that will fail builds of textures are uncompressed and report to a log w$$anonymous$$ch textures they are, t$$anonymous$$s is for the sake of build automation.

I looked over in the documentation for somet$$anonymous$$ng that could help but couldn't find anyt$$anonymous$$ng, is anyone aware of any post/pre build attributes or hooks that could help accomplish t$$anonymous$$s goal?

Thanks
