made illustrations) included in a software package that you can insert into any document, publication, etc.

Bitmap Graphics vs Vector Graphics

• Bitmap Graphics– Made up of colored pixels• very small rectangles

of varying colors that together give you an image. • They do not enlarge

well• Usual file formats

include .gif, .jpeg .png

Bitmap Graphics vs Vector Graphics

• Vector Graphics–Made up of

mathematical expressions and instructions to produce lines, curves, shapes

–Will not lose quality when enlarged

Vector Example

Transparent vs Opaque• Opaque– Every pixel in the image is visible.

• Transparent– Every pixel in the image is either

completely visible or completely see-through.

– In the image, the white background could be transparent so that what's "underneath" the image shows through when it is drawn.
