bitmap
An image represented by pixels and stored as a collection of bits in which each bit corresponds to one pixel. On color systems, more than one bit corresponds to each pixel. A bitmap usually has a .bmp file name extension.
A Glossary of Internet & PC Terminology
Where data is represented in the form of individual bits. These individual bits make up the file. A simple bitmap image is made up of tiny little parts called pixels. Bitmap files are most commonly used as graphics or pictures. Bitmap Files have a file extension of BMP. Below is an example where the Number 2 has been removed from a picture and magnified several times to show how it has been constructed.
INTERNET TERMS&ACRONYMSV1.0
A graphic which is defined by specifying the colors of dots or pixels which make up the picture.Also known as raster graphics.Common types of bitmap graphics are GIF,JPEG,Photoshop,PCX,TIIF,Macintosh Paint,Microsoft Painty,bmp,PNG,FAX formats,and TGA.
Glossary of Computer and Internet Terms
Most pictures you see on your computer, including the ones found on the Internet, are composed of bitmaps. A bitmap is a really just a map of dots (or bits, hence the name) that looks like a picture as long as you're not like 2 inches from the screen. Common bitmap filetypes include BMP, JPEG, GIF, PICT, PCX, and TIFF. Because bitmap images are made up of a bunch of dots, if you zoom in on a bitmap, it gets all blocky. Vector graphics (created in programs such as Freehand, Illustrator, or CorelDraw) scale up much better without getting blocky.
Multimedia Glossary
A windows format for storing graphics.

Steve's Digicams Digital Camera Dictionary
The method of storing information that maps an image pixel, bit by bit. There are many bitmapped file formats, .bmp, .pcx, .pict, tiff, .tif, .gif, and so on. Most image files are bit mapped. This type of file gives you the 'jaggies', when examined closely you can see the line of pixels that create the edges.
Win32 API(Application Program Interface)
The BITMAP structure defines the type, width, height, color format, and bit values of a bitmap.

typedef struct tagBITMAP { // bm
LONG bmType;
LONG bmWidth;
LONG bmHeight;
LONG bmWidthBytes;
WORD bmPlanes;
WORD bmBitsPixel;
LPVOID bmBits;
} BITMAP;


Members

bmType

Specifies the bitmap type. This member must be zero.

bmWidth

Specifies the width, in pixels, of the bitmap. The width must be greater than zero.

bmHeight

Specifies the height, in pixels, of the bitmap. The height must be greater than zero.

bmWidthBytes

Specifies the number of bytes in each scan line. This value must be divisible by 2, because Windows assumes that the bit values of a bitmap form an array that is word aligned.

bmPlanes

Specifies the count of color planes.

bmBitsPixel

Specifies the number of bits required to indicate the color of a pixel.

bmBits

Points to the location of the bit values for the bitmap. The bmBits member must be a long pointer to an array of character (1-byte) values.

Remarks

The bitmap formats currently used are monochrome and color. The monochrome bitmap uses a one-bit, one-plane format. Each scan is a multiple of 32 bits.
Scans are organized as follows for a monochrome bitmap of height n:

Scan 0
Scan 1
.
.
Scan n-2
Scan n-1
Bitmap Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits, that is, values which are zero or one. It is also called a bit array or bitmap index.
