Bitmap: An image format that only defines an image in terms of black and white.GIF: Graphics Interchange Format, is a compressed graphic file normally used for images that do not require too many colors (maximum 256).
PNG: PNG is a graphics format specifically designed for use on the World Wide Web. PNG enable compression of images without any loss of quality, including high-resolution images.
JPEG: JPEG graphics are capable of reproducing a full range of color while still remaining small enough for Web use. Most of the photographs you see on the Web are JPEG format.
XCF:
PSD: the default proprietary file of Adobe Photoshop. It allows for Adobe Photoshop formatting, Layers, DropShadows, etc. and is compatible with a variety of Adobe software such as InDesign.
SVG: Scalable Vector Graphics is a vector graphics language written in XML. Using SVG, graphics can be coded directly into an XML document.
What is an alpha channel?
alpha compositing is the process of combining an image with a background to create the appearance of partial transparency. It is often useful to render image elements in separate passes, and then combine the resulting multiple 2D images into a single, final image in a process called compositing. For example, compositing is used extensively when combining computer rendered image elements with live footage.SOURCE: wikipedia.com
