Notes Raster formats: These formats store images as bitmaps (also known as pixmaps).
RAW: RAW refers to a family of raw image formats that are options available on some digital
cameras.
SVG (Scalable Vector Graphics): SVG (Scalable Vector Graphics) is an open standard created and
developed by the World Wide Web Consortium to address the need (and attempts of several
corporations) for a versatile, scriptable and all-purpose vector format for the web and otherwise.
TIFF (Tagged Image File Format): The TIFF (Tagged Image File Format) format is a flexible
format that normally saves 8 bits or 16 bits per color (red, green, blue) for 24-bit and 48-bit totals,
respectively, usually using either the TIFF or TIF filename extension.

Vector file formats: Vector file formats can contain bitmap data as well. 3D graphic file formats
are technically vector formats with pixel data texture mapping on the surface of a vector virtual
object, warped to match the angle of the viewing perspective.
