RASTER & VECTOR FILES
![Page 2: RASTER & VECTOR FILES. Raster images use many coloured pixels or individual building blocks to form a complete image. JPEG, BMP, TIFF, GIF are common.](https://reader030.fdocuments.in/reader030/viewer/2022032415/56649f045503460f94c186b1/html5/thumbnails/2.jpg)
Raster images use many coloured pixels or individual building blocks to form a complete
image. JPEG, BMP, TIFF, GIF are common raster image types.
**The data is in the pixel quantity & colour

Common raster image types when you do a general ‘picture’ search.

Raster images are specified in terms of their resolution, this is specified in terms of dpi
(dots per inch)
All raster image downloaded or photo taken will have a physical size and a dpi specification.

Vector graphics is the use of geometrical primitives such as points, lines, curves.
These are based on mathematical expressions, the colour/grading is also mathematical.
Graphic file types EPS, AI, PDF & export as DXF

You can download these as images, (subject to copyright), & they will be raster files.

Laser Cutting & EtchingThe cutting data is a Vector line around the
perimeter....the red outline of the tree
In a Laser Cutter the laser follows the vector path. With a computer controlled machining process the cutter follows the vector path.
When etching using a Laser Cutter the data for the depth of the etch comes from the
different grey tones.
The darker the grey the more energy goes into the laser & the deeper the etch.

High resolution image required...High Resolution image = better quality tracing.
Low Resolution image = poor quality tracing
