AGC will convert all NGA's Arc Digital Raster Graphics
(ADRGs) into GeoPDFs.
To parse the difference a bit further: The salient point is that raster graphics
are resolution dependent, with the quality of a given image deriving from the concentration of information in each pixel and the number of pixels ranged across a bitmap.
In researching what resolutions were used, I found that the USGS Digital Raster Graphics
(DRGs) made before October 2001 were scanned at the resolution of 250 dpi.
Because a bitmap uses a fixed or raster graphics
method of specifying an image, the image cannot he immediately rescaled by a user without losing definition.

Daytona Visual Marketing, set up 20 years ago, demonstrated the capabilities of the Raster Graphics
digital printer with the output of Birmingham City Council's 'Brummies are proud people' campaign, designed by Wallis Tomlinson.
The actual transfer of raster data is defined under MIL-R-28002A, Requirements for Raster Graphics
Representation in Binary Format.
The digital display on the computer remains crisp and clear as the user zooms in to look at the map in more detail--unlike Compressed ARC Digitized Raster Graphics
Arc-Digitized Raster Graphics
(ADRG), a 254-dots per inch (dpi) scan of NIMA hardcopy products.
It aims to unify a number of application services: user interface, 2D and 3D drawing, fixed and adaptive documents, advanced typography, vector graphics, raster graphics
, animation, data binding, audio and video.
Multimedia algorithms available in the starter kit include JPEG, MJPEG, Ogg Vorbis, Speex, and a Simple Raster Graphics
