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.

Overview
WebP is a file format which uses both lossy and lossless compressions to encode the files. It was developed by Google in order to facilitate the work online which can be done quickly and easily with this extension. This is a sister project of WebM Multimedia container and it produces high quality of images. It is claimed that it can reduce the file size by 34% without affecting the quality of a photo. Due to this reduced size, online work can be done in less time as these files can offer high speed over the Internet due to small size. This format provides add-on support to the lossless algorithm, metada, transparency, colour profile and animation.
Technical description
Intra frame coding that is used in video format and the resource interchange file format, are base for its lossy compression. Only 16,383 pixels can be used to represent the side length of an image. Besides this, it is based on block prediction in which every block is forecasted as per the values, from the three blocks above it and from a one block to the left of it. Horizontal, vertical, DC (one colour) and Truemotion are the four basic modes of block prediction in this extension. Animated images can also be produced using WebP and this is a substitute to famous GIF format. It comes with many improved features. For instance, 24 – bit colour with transparency, joining of frames with both lossy and lossless compressions in the same animation and providing support to seek to a specific frame.
