Bitmaps are also known as pixelmaps or raster graphics. Bitmap images are organised as a grid of coloured squares called pixels (short for ‘picture elements’). When zooming in or enlarging a bitmap image, the pixels are stretched and made into larger blocks.

Which is better BMP or PNG?
BMP files are uncompressed and lossless. They’re large files that retain as much detail as possible. PNG files, on the other hand, are compressed and lossless. Their smaller file size and compression capabilities can make PNGs easier to use.
Which is better PNG JPG or BMP?
PNG is a good choice for storing line drawings, text, and iconic graphics at a small file size. JPG format is a lossy compressed file format. This makes it useful for storing photographs at a smaller size than a BMP. JPG is a common choice for use on the Web because it is compressed.
What is a bitmap image file teach ICT?
This is a file format for digital images. A bitmap is made up of a large number of dots (called pixels) arranged in a set of horizontal rows and columns For example a 600 by 800 pixel bitmap has 600 rows and 800 colums forming a rectangular image. Bitmaps can be either compressed or uncompressed.
What does each pixel in a bitmap image contain?
Each pixel in an indexed color image is described by a number of bits (1, 4, or 8) which is an index of a single color described by this table. The purpose of the color palette in indexed color bitmaps is to inform the application about the actual color that each of these index values corresponds to.
Why would the media use bitmap images?
Bitmaps are usually the best choice for websites as screen resolutions are relatively low compared to print or other types of media. When it comes to these other types of media (like printing) it’s a matter of choosing which format will look the best on the final product.

Today however, all major browsers support the SVG (Scalable Vector Graphics) format.
Is a BMP a vector file?

Advantages of bitmap files include the following: Bitmap files may be easily created from existing pixel data stored in an array in memory. Retrieving pixel data stored in a bitmap file may often be accomplished by using a set of coordinates that allows the data to be conceptualized as a grid.
