| Overview |
| This file extension is capable of storing only monochromatic images that are black and white. This format has become now outdated and it was used by early mobile phones for exchanging and storing the monochromatic pictures that were sent using SMS messaging service. The successor to this is PNG which supports colours. As mobile phones have come up with improved and enhanced features that is why this format has been largely replaced by full-colour image and video formats. This extension has many likenesses with BMP files that is the standard bitmap images. WBMP does not support grayscale images as well as colour images. The size of the file is small and is always kept in reduced size. |
| Technical description |
| In this WBMP format, pictures are created by using pixels in which 0 (zero) is assigned to black pixel and 1 (one) is for a white pixel. There are certain fields which are present in this file extension. The field names are as follows along with their purpose. The first one is type, it tells about the type of an image and zero is fixed for monochrome bitmaps. The next is a fixed header and it is always reserved with 0 value. Then comes the width and this defines the breadth of an image in pixels. The second last is the height and it represents the height of a photo in pixels. The last one is data and it tells about the data bytes arranged in rows. |

| Overview |
| Files stored in this format are small in size that is why they can be uploaded and downloaded with ease. It takes less time over the internet to upload and download due to smaller size which results in saving of bandwidth. This extension is compressed using a lossy algorithm that is why there can be a reduction in the quality of the photograph. It has the ability to compress the file to one-tenth of its original size. It is widely used in emails and also when images are to be posted on websites. Digital Cameras and other photographic image capture devices widely use this JPG format. The paintings and photos of realistic scenes that have smooth variations of colour can be best illustrated by this format. |
| Technical description |
| A technique used in JPEG format to compress files is lossy compression which is based on DCT (Discrete Cosine Transform) as it is the most practical Mathematical operation. The DCT actually converts each frame of the video from the spatial domain to a frequency/transform domain. It discards the information of high frequency that has sharp transitions in intensity as well as in colour hue. Furthermore, this standard defines a codec which tells how an image can be encoded into a stream of bytes and decoded back into an image. The files can be compressed in the ratio of 100:1 but that would result in the poor quality of an image. Therefore, to retain the quality of a photo, a file should be compressed till 20:1 ratio not more than that. |
