Storing+graphic+data

Introduction
There are 4 main image file formats which store data as a form of bitmapped graphic i.e. they store information on the colour and placement of each pixel. The image types are:
 * Bitmap (BMP)
 * Graphic Interchange Format (GIF)
 * Joint Pictures Expert Group (JPEG)
 * Portable Network Graphics (PNG)

Compression

Task 1
Investigate each of the file types above (BMP, GIF, JPEG & PNG), and write a blog post summarising how each of the 4 works. In addition, your post should include the following information:

Bitmap: Colour look-up table (CLUT), run length encoding (RLE), 24 bit bitmaps, RGB colour codes GIF: Animation, transparency, LZW compression, interlacing JPEG: Compression technique, Huffman compression PNG: CLUT or RGB, transparency, compressed
 * Higher only**

Bitmap: Uncompressed GIF: 256 colours, transparency, lossless compression JPEG: Lossy compression
 * Int 2 only**

Task 2
Using a bitmapped graphics package you are familiar with, create an image and export it in each of the 4 formats above. Note the different files sizes for each.

Investigate the way in which the package compresses the different file formats. Write these down.
