original

The original document or picture to be scanned.

output

The file that is generated by the scanning process.

output dimensions

The actual height and width of an image when saved. You will not see
the size changes to your image in the Preview area since image size
affects only the final scan.

The type of file that is generated during the scanning process. Output
type reveals the bit depth of the image.

p

palette

A subset of the color look-up table that establishes the colors that can
be displayed on the monitor at a particular time. The only color depth
that allows multiple palettes is the 256 (or 8-bit) color setting for your
monitor. At a color depth of 256 colors, each program (or even each
individual image used or edited in a program) can have a different
color palette.

palette flashing

The flashing that occurs when your monitor is set to a color depth of
256 colors and you switch programs. When you switch programs, the
palette of the active program becomes the system palette, and all other
programs redraw themselves as accurately as possible with the new
colors.

PDF

Portable Document Format (PDF) format. Adobe Acrobat files use this
format.

PICT

Apple's proprietary image file format that is used by the Macintosh
operating system. Designed for the screen, this format is best used for
color images that will not be printed. Images saved as PICT files are
smaller in size than images saved as a TIFF files.

pixel

The smallest element (picture element) that can be assigned an
independent color and intensity and can be displayed on a computer
screen. Pixels are square dots arranged in a grid pattern to make up
the images displayed on the screen.

plug-in

A module that integrates into a program to provide additional
functionality. The HP PrecisionScan Pro Installer adds a Photoshop
plug-in (the HP ScanJet Plug-in) for image editor and OCR programs,
which allows you to scan text and images from within these programs.

PNG

Portable network graphics format. A compressed image file format
suitable for the Web that might replace GIF because of copyright
issues with GIF format. PNG is non-lossy compressed, supports
interlacing, and can be used with the True Color output type, which
GIF cannot.

pop-up menu (or list)

A menu of items that appears when you click on or pass the cursor
over a command.
