Jus from the top of my head from IPT
1) GIF: Graphical Interchange Format. It is a lossless file compression. Symboles (as they call it) are used to replace repeated patterns/colours. Lossless compression allows image to retain its original quality via reverse process. Compared to JPEG the GIF image quality is less because it only allow 256 colours. Requires less storage, poor image quality.
2) PNG: Portable Network Graphics. [??? Will attend to immediately]
3) JPEG: Joint Photographic/Picture Expert group. It is a lossy file compression. Has available +6 million colours to represent image, thus greater quality compared to GIF. Its a compressed file format that doesnt sacrifice too much quality.
4) XLS: [??? Will attend to immediately]
5) TIFF: Tagged Image File Format [??? Will attend to immediately]
6) BMP: Bit-Map. Example of bit map is JPEG/GIF. Image made up of pixels. Each pixel is represented by bits (Os & 1s) this is known as bit depth. The more number of bits used to represent a pixel leads to larger file size, more storage space required. To find out the file size of a Bit map image simple note its resolution and its bit depth. Eg: find the size of an image with resolution of 800*600 with 64 colours (2^6 where 6 is the bit depth).
(800*600*6)/(8*1024) calculation is in kb.
Note
8(Byte)
8*1024 (Kb)
8*1024^2 (Mb)
8*1024^3 (Gb)
Also vector graphics is image made up of lines & shapes. Example of Vector is WMF stands for Windows Meta File.
