byte
8 bits, reflecting values between 0 to 255; used as a basic
method of measurement of memory or disk size; “K”
represents 1024 bytescolor correctness
the depth and accuracy of an image’s color representation,
typically influenced by the color depth and palette of an
imagecolor depth
the amount of color information in an image, reflected in the # of color bits compression, lossless scheme of organizing information in a more compact form where all of the original information is retained, while gaining a moderate level of compactioncompression, lossy
scheme of organizing information in a more compact form
where some information is lost to gain higher levels of
compactioncmyk
the four process colors — cyan, magenta, yellow and black
— mixed to provide a color image; typically used in printing
applicationsdib
Device Independent Bitmap, a variant of a bitmap (bmp) file consisting of header field, an optional pallette, and bitmap data; bitmap has an additional header fielddisplay quality
the characteristics of a display sub-system, such as
resolution, # of colors, dot pitch, and refresh rate, which
influence perceived image qualitydithering
the technique of making adjacent pixels different colors to
make them appear like a different color; utilized to add the
appearance of greater color depth with a limited # of colorsdot pitch
distance in millimeters between two holes in the shadow
mask of a monitor. A smaller dp is better, e.g. 0.28 mm is
better than 0.36.dpi, dots per inch
sometimes termed pixels per inch, this depicts resolution and is a significant influence on the size of an image file; a higher dpi indicates higher resolution
eps
Encapsulated PostScript file format, an Adobe Systems
graphics file which incorporates PostScript code and can
contain data as vectors or bitmaps; maximum color depth =
16.7 milliongif
Graphics Interchange Format, a lossy compression
technique, popular for exchanging files electronically,
especially on Compuserve; all files have a corresponding
palette; maximum colors = 256jpeg
Joint Photographers Expert Group; a compressed, lossy
format which is symmetrical, i.e. takes the same amount of
time to compress as decompress; maximum colors = 16.7
millionlpi, lines per inch
measurement of the frequency of “dots” represented in a
halftone image
mpeg
high-quality video compression/decompression scheme
(CODEC) for encoding video and audio for computer
playbackpalette
data structure defining the colors utilized in a bitmap image;
bitmap data is indexed to the palette tablePhoto CD
Kodak CD-based digital imaging format, where images are
typically created from 35mm film negatives or slides; includes multiple resolutions of an image in an Image Pac, with all images 24 bpp encoded in YCC format; portability includes Philips CD-Interactive and 3DO Players, as well as PC, Mac & Unix viewers; maximum colors = 16.7 millionpcd
see Photo CDpcx
ZSoft format, used widely for paint and desktop publishing
programs; popular for exchanging images; maximum 16.7
million colorsPICT
standard format for Macintosh, can contain both vector and
bitmap information; maximum colors = 16.7 millionpixel
picture element, or the smallest unit of the computer screen.
A pixel can be monochrome or up to the pixel depth
available on your color system. Pixels are also used for
identifying screen resolution, e.g. 72 pixels per inch.pixels per inch, or ppi
sometimes termed dots per inch, this represents resolutionprint quality
the characteristics of a printing sub-system, such as the
number of lines per inch and paper quality, which influence
the perceived quality of a printed imagequicktime
a video compression/decompression scheme (CODEC) for
encoding video and audio for computer playback; originally
an Apple Macintosh file format, it is now commonly utilized
on Windows and Unix systemsresolution
measure of the detail in an image; the higher the resolution,
the higher the amount of detailRGB
red, green, blue mixed to provide a color image, typically
used in video display applicationsTGA
Targa format developed by Truevision; usually 15 or 24 bit
full color images, compressed or uncompressed; maximum
colors = 16.7 milliontiff
Tag Image File Format; industry standard image file format;
“tags” represent image attributes, compression, and color
tables; both uncompressed and compressed versions,
although compressed is not as portable; maximum colors =
16.7 millionvector graphics

excellent posts/tips guys. but could you do me a favour. put under the post at the bottom the name of the site that you have taken the information from. if this is copyright material im afraid ill have to delete it.
im all for posting information found on the web if it has been put on for this purpose. “shariing” but merely cutting and pasting another sites info is not somthing i would personaly like done to me.
