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).

Overview

This EXR extension stores the raster or bitmap images, which are dot matrix structures. It is also an open standard format with a free software license. It works effectively with HDR images(High Dynamic Range). The pictures that are stocked using this format can have either lossy or lossless compression. It has the capability to keep photographs of high luminance and colour. It supports pictures of multiple layers that possess high quality. This format is used by many photo editors in order to add visual effects as well as animation due to its flexibility in compressing the images to both lossy and lossless algorithms.

Technical description

EXR can support multiple channels with varied pixel sizes that are 32-bit and 16-bit floating-point values. It contains arbitrary channels and it can cover multiple points of view. For instance, the left side and right side camera images. Composting is an enhanced feature in this format which allows assembling of numerous pictures to one final photo. There is no need to make separate files for storing the information of arbitrary channels like diffuse, alpha, specular; as all can be combined to one file of this type. A compositor can also modify the specific channel if he is not satisfied with the current appearance of specular reflections or specularity. It has different compression methods for varied types. For grainy images PIZ algorithm is suitable and images that are without a lot of grain, ZIP compression works the best.
