A Monochrome bitmap is black and white bitmap file. A monochrome bitmap is a rectangular grid of pixels, 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-colored images.
16/24/256 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 there are, the bigger the file size and the higher the definition of the image.
JPEG -
In computing, JPEG is a commonly used method of lossy compression for photographic images. The degree of compression can be adjusted, allowing a selectable tradeoff 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 that was introduced by CompuServe in 1987 and has since 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 Macintosh owners, graphic artists, the publishing industry, and both amateur and professional photographers in general. As of 2009, 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.
