higher graphics - file types

DTP Raster

use pixels to display photos / images. The more pixels the better the quality for zooming in, but poor quality of low resolution

Jpeg

a type of DTP Raster. Used to be the most common image format as low file size, by now superseded by PNG

Bmp

a type of DTP Raster. Huge image files as they retain all their information but can’t be compressed or used in transparencies

Png

a type of DTP Raster. The best image format for digital photo use on websites etc, as files are small, sharp and clear, good for transparencies

Tiff

a type of DTP Raster. Most commonly used in graphic design as it can store high quality images and can be compressed. Best for photos that can be used in books and packaging instead of just digitally.

DTP Vectors

used for designing graphics such as cartoons / CAD models and scale up and down with no loss in quality as uses mathematical vector program. Not photos

Svg

a type of DTP vector. can be created in 2D and enlarged without losing any quality, but is a small file size. Isn’t good for using in transparency

Dxf

a type of DTP vector. Used for file to work across CAD and vector packages so you can create a drawing in either package and transfer it over for further work

3ds

a type of CAD vector. stores information on the makeup of 3D vector graphics and includes material finishes, lighting styles, which make it good for animation

Step

a type of CAD vector. Intended for creating, editing and sharing 3D Cad models across various CAD programs. Standardised file format, makes sharing easier

Iges

a type of CAD vector. Smaller than Step files and more suited to surface modelling CAD files. Designed to transfer 2D and 3D data between CAD systems.
