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 extension is particularly used to store Raster images. It was developed for the first graphic cards so that they can provide support to high colour or true colour displays. This group aimed at professional computer image synthesis and also at video editing in personal computers. Every colour which is available is defined with the help of palette. TARGA stands for Truevision Advanced Raster Graphics adapter and TGA is an initial for this adapter. This file format is quite popular in animation as well as video industry. The size of the files is large due to the characterization each pixel of an image by a particular number of bits. Depending upon the situation, data can be compiled using a lossless RLE (Run-length encoding) compression or can be stored in raw form as well. It should be noted that this compression is suitable only for icons, cartoons and line drawings not for photographic images. |
Technical description |
TGA is capable of storing photos of 8,16,24 and 32 bits of accuracy per pixel. In addition to this, 24 bits of RGB and 8- bit for alpha channel. Furthermore, it only contains an 18-byte header which is followed by image data. A header in it consists of ID length, colour map type, image type, colour map specification and image specification. Image ID can store any kind of information but generally, it either has a date and time the image was created or a serial number. There can be optional sections as well like developer area, extension area and file footer; etc in order to add extra information. |
