Image Types
Monochrome Bitmap -
A Monochrome bitmap is black and white bitmap file, but each
pixel is represented by a single bit. Eight pixels are in each byte of the
bitmap. Monochrome bitmaps are often used for bitmapped text or single-coloured
images.
Colour Bitmap -
A representation in which each item corresponds to one or
more bits of information, esp. the information used to control the display of a
computer screen. The more bits, the bigger the file size and the higher the
definition of the image.
JPEG -
The degree of compression can be adjusted, allowing a
selectable trade-off between storage size and image quality. JPEG typically
achieves 10:1 compression with little perceptible loss in image quality.
GIF -
The Graphics Interchange Format (GIF) is a bitmap image
format and has come into widespread usage on the World Wide Web due to its wide
support and portability. It is a popular format for image files, with built-in
data compression.
TIFF -
Tagged Image File Format (abbreviated TIFF) is a file format
for storing images, popular among Apple owners, graphic artists, the publishing
industry, and both amateur and professional photographers in general. it is
under the control of Adobe Systems.
PNG -
Portable Network Graphics (PNG) is a bitmapped image format
that employs lossless data compression. PNG was created to improve upon and
replace GIF (Graphics Interchange Format) as an image-file format not requiring
a patent license.
