Dots Per Inch (DPI) and Pixels
per inch (PPI)
Technically DPI refers only to how
many dots per inch a printer is capable of printing. PPI refers to how many
pixels per inch the image actually contains irrespective of how many dots per
inch (dpi) a printer is capable of producing.
However the terms dpi and ppi have
become corrupted by numerous sources so that the terms DPI and PPI are used
almost interchangeably.
The correlation between dots and
inches is seen in the table below. As the human eye cannot discern quality
levels over 300dpi in printed material, 300dpi is the chosen, and industry,
standard for high quality print images.
If you attempt to increase the
physical size of an image above the limit of its pixel resolution (ppi) the
result will be a pixilated or poor quality image, no matter the dots per inch
resolution (dpi) it is printed at.
Digital scrapbookers need to
ensure that each element in a layout has the required pixels per inch (ppi) to
create a quality print at 300 dots per inch (dpi). The formula for this is

Per Inch
Resolution
describes the clarity or level of detail of a digital image.
Technically the term "resolution" refers to spatial resolution
and brightness resolution;
commonly, however, the word is used to refer to spatial resolution alone. The
higher the resolution, the greater the detail in the image (and the larger the
file). For computers, digital cameras
and scanners,
resolution is measured in pixels per inch
(ppi); for printers, resolution is measured in dots per inch (dpi).
.JPEG/JPG Joint Photographics

extensively for photographs and for web imaging. Uses lossy compression which

Copy and Paste
Copy-and-paste
is a simple method of reproducing text or other data from a source to a
destination. The task can be done using keyboard shortcuts – control key
held down while typing the letters X (for cut), C (for copy), and V (for paste),
or with the mouse by right clicking with the mouse button and choosing the
desired function or using an applications menu or by dragging and dropping. The
information is copied to a location called the clipboard as a temporary means of
storage.
Cut and paste
Cut and paste is a means of moving
text or other data such as images from a source to a destination. The task can
be done using keyboard shortcuts – control key held down while typing the
letters X (for cut), C (for copy), and V (for paste), or with the mouse by right
clicking with the mouse button and choosing the desired function or using an
applications menu. Sometimes, if a section of text is cut and a different
section of text is cut after it, the first section of text will be cut out of
existence, with no way to retrieve it. This only applies to cut and paste
programs that can only hold one thing on the clipboard. This is usually not a
problem for clipboards that can hold multiple cuts.

Pixel see also ppi and
resolution
A pixel (a contraction of
picture element) is one of the many tiny dots that make
up the representation
of a picture in a computer's
memory. Usually the dots are so small and so numerous that, when printed on paper or
displayed on a computer monitor,
they appear to merge into a smooth image. The colour and intensity of
each dot is chosen individually by the computer to
represent a small area of the picture.

A raster graphic is a data file or
structure representing a generally rectangular
