Overview |
GIF is an image format which is known worldwide and it is used as a second option after JPEG. It offers high portability between OS(Operating Systems) and applications. Each picture can support up to 8 bits per pixel, as a resultant, it enables an image to have a separate palette of up to 256 distinct colours that are taken from the 24-bit RGB colour space. Furthermore, it is commonly used for web graphics, logos with solid colour and also for animated images. These files are saved as ‘animated GIFs' and it displays general animations on websites. Besides this, this format has the capability to blend varied colour backgrounds due to the presence of transparent pixels. It should be noted that pixels should be either fully transparent or opaque so that it doesn’t result in the faded picture. |
Technical description |
GIF is an inadequate format for colour photographs due to palette limitations. It enables an independent palette of up to 256 colors for a solo frame. These files are compressed using a lossless data compression algorithm known as LZW( Lempel-Ziv-Welch) and this algorithm was created by Abraham Lempel, Jacob Ziv and Terry Welch. It removes the unwanted colours that are not in use to compress raster data. The maximum limit which is permitted for colours is 256 and the minimum is 2 (black and white). Apart from this, it has a fixed-length header which gives the version and pixel dimensions are provided by the ‘logical screen' descriptor. |

Overview |
This file extension is capable of storing only monochromatic images that are black and white. This format has become now outdated and it was used by early mobile phones for exchanging and storing the monochromatic pictures that were sent using SMS messaging service. The successor to this is PNG which supports colours. As mobile phones have come up with improved and enhanced features that is why this format has been largely replaced by full-colour image and video formats. This extension has many likenesses with BMP files that is the standard bitmap images. WBMP does not support grayscale images as well as colour images. The size of the file is small and is always kept in reduced size. |
Technical description |
In this WBMP format, pictures are created by using pixels in which 0 (zero) is assigned to black pixel and 1 (one) is for a white pixel. There are certain fields which are present in this file extension. The field names are as follows along with their purpose. The first one is type, it tells about the type of an image and zero is fixed for monochrome bitmaps. The next is a fixed header and it is always reserved with 0 value. Then comes the width and this defines the breadth of an image in pixels. The second last is the height and it represents the height of a photo in pixels. The last one is data and it tells about the data bytes arranged in rows. |
