Pixel graphics
Graphical elements are described as vectors:
information about start and end point, thickness
and colour of a line, possibly fill pattern and colour
gradient.
Pixel graphics of modern digital cameras have 5
million and more pixels (resolution
= 5 megapixels). A special data compression tries
to reduce the required high memory space.
Unfortunately, compression leads to a poorer
quality.
Reduction or enlargement is easy and leads to no
quality loss (
example below).
Enlargement leads to block graphics or blurry
images (
example below).
Reducing such a megapixel image results in high
loss of image information.
Example:
Original Ø 10 mm / enlargement 5 times
EPS file 35 kB
Example:
Original 30 x 30 px / enlargement 5 times
BMP file 3 kB / 62 kB
