• It is an artifact that depicts or records visual perception.
• It may be two -dimensional or three – dimensional.
• It is an created or copied and stored in an electronic form.
• described in two types vector images and raster mages.

• Lossless compression
Algorithms reduce file size while preserving a perfect copy of the original
uncompressed image.
 Lossy compression
Algorithms preserve a representation of the original uncompressed image
that may appear to be a perfect copy.

• Best suited for storing simple graphic images with relatively few colors.
• It is not well fitted for photographic works.
• It used extensively on the Internet and Multimedia applications because of the
great support for animation.

• Jpeg files can be relatively small in size, but they still look crisp and beautiful.
• supports full color up to 16.7 million colors.
• require more computational power to process.
• trouble with JPEGs is overcompression.

• the ability to incorporate low-resolution images that load quickly but also look
great.
• Gifs are either transparent or opaque
• file format was created as the free, open-source successor to GIF.
• Compared to JPEG, PNG excels when the image has large
• PNG format is best suited for pictures still under edition

11. Exchangeable image file format
11
• Format is a file standard similar to the JFIF format with TIFF extensions.
• Its purpose is to record and to standardize the exchange of images.
• The actual exif metadata as such may be carried within different host formats
• File extension is .Exif

12. Windows bitmap
12
• The BMP file format handles graphics files within the Microsoft Windows
OS.
• BMP files are uncompressed, hence they are large
• The advantage is their simplicity and wide acceptance in Win programs.
• File exetension is .bmp

14. Computer Graphics Metafile
14
• file format for 2D vector graphics, raster graphics.
• It provides a means of graphics data interchange for computer
representation of 2D graphical information independent from any
particular application, system, platform, or device.
• largely been superseded by formats such as SVG and DXF.

• created and developed by the World Wide Web Consortium
• SVG format does not have a compression scheme
• SVG graphic can be compressed using a program such as gzip

19. Tagged Image File Format

• format is a flexible format that normally saves 8 bits or 16 bits per color
• TIFFs can be lossy and lossless
• Problem is reader that reads every type of TIFF file does not exist
• TIFF image format is not widely supported by web browsers.
• File extension is .TIFF or TIF
