OverviewThese files are commonly termed as ‘ping' and they store the raster files using lossless compression. It came into existence in order to replace the GIF file format as they both have the ability to show transparent backgrounds. Furthermore, it was an enhanced and improved version of Graphics Interchange format. It supports different types of photos. The first one is palette-based photographs that can either have palettes of 24-bit RGB or 32-bit RGBA colours. Second is grayscale images which may or may not have an alpha channel for transparency. Lastly, there is a full-colour non-palette which is based on RGB/RGBA pictures. There is one limitation of this type. It does not support animation like GIF. Besides this, it is non-patented which means there are no copyright limitations.
Technical descriptionThe expanded features like 8- bit channel for transparency and 24- bit RGB support make PNG more popular. The files stores in this format allow the fading of colours from opaque to transparent which is not present in the preceding format. CMYK does not offer support to this extension as it was developed for transferring of files over the internet, not for professional-quality print graphics. It stores information like textual comments, integrity checks and encoded basic pixels in its extensible structure of chunks. It always starts with an 8-byte signature followed by a series of chunks. A chunk furthermore comprises of four parts- length (4 bytes), chunk type (4 bytes), chunk data (length bytes) and CRC- Cyclic redundancy checksum or code (4 bytes).

BMP Technical Specifications

File extension.bmp
File categoryImage file (Raster)
Stands forBitmap image file
DeveloperMicrosoft
OverviewBMP 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 descriptionBMP 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).
