Overview |
| BMP format is used for Raster images. These images contain a grid of pixels and each pixel further depicts an individual colour within the image. In this, there can be varying levels of colour depths per pixel, as this criterion is entirely based on the file header which tells about the number of bits per pixel. The images stored is often uncompressed when they are 16 bpp and 32bpp. It is capable of storing only 2-dimensional images( both monochrome-single colour and colourful, with numerous colour depths). A user does not require a graphics adapter to view this file. It is not a popular format these days as it takes lots of time to upload, send and download, due to its large size. |
Technical description |
| BMP file format comes up with the option of data compression, colour profiles and alpha channels. Alpha composting results in partial or fully transparent images which are done by incorporating or mixing one image with a background. Exchanging bitmaps between devices and applications is possible due to a unique representation of colour bitmaps of distinct colour depths, defined by Microsoft. That is why it is termed as a device-independent bitmap file format(DIBs). Additionally, it has both fixed-size and variable-sized structures. This format follows structures in the order given ahead- bitmap file header(stores general information), DIB header(Contains detailed information including pixel format), Extra bitmasks(Define pixel format), colour table( define colours used), Gap 1(Structure alignment), a Pixel array(Actual values of a pixel), Gap 2(Structure alignment)and ICC colour profile(Colour management). |

File extension |
| tga |
File category |
| Raster Image |
Stands for |
| Targa Graphic File |
Developer |
| Truevision Inc. (Currently part of Avid technology) |
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. |
