The RGBA extension identifies files commonly known as Raw red, green, blue, and alpha samples. It contains low-level pixel or channel data whose dimensions and sample layout may need to be supplied separately. Imaging and video tools use the expected color model and geometry to display, process, or convert the raw picture.

The FB2 extension identifies files commonly known as FictionBook. It packages a digital publication with text and any supported navigation, styling, images, or metadata. Compatible reading applications can organize and display the title, while ebook tools can edit or convert it for other devices and libraries.
