Own formats, both of which are called BMP. There are actually several BMP formats (BitMaP). Vector Magic recommends using the PNG format when storing logos as bitmaps. This format is widely supported by web browsers and image viewers/editors. The best of the lossless image formats is called PNG (Portable Network Graphics). They are more suitable for things like logos. These store an exact pixel-by-pixel representation of the image, but require more space. We do not recommend using JPEG files for rasterized vector art, as the compression artifacts substantially degrade the quality of the image near edges. It has excellent compression characteristics and has the nice feature that the user may specify what level of compression they desire, trading off fidelity for file size. One of the most widely-used image formats. They are also commonly used on the web to save bandwidth. They are best suited to photographs and other images where perfect accuracy is not important. These have smaller file sizes but do not store a perfect copy of the image. Some of the most common are: JPEG, PNG, GIF, BMP, and TIFF.īroadly speaking, they fall into two categories: Lossy formats In this case, the reduction in image quality can vary from insignificant to substantial.There is a large number of different bitmap formats. The file compression ratio is in the range from 10:1 to 100:1. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. JPEG (JPG) uses a 'lossy' compression system and discrete cosine transform technology. Finally, the colors and brightness are coded. First, the photo is transformed into a color space YCbCr, then it is divided into squares to determine the upper range of the color spectrum. The procedure for compressing the digital images in JPEG (JPG) format is carried out in several stages. It is not recommended to use this format for compression of drawings and various kinds of graphics, since a strong contrast between a number of closely located pixels provokes the appearance of visible artifacts. The JPEG (JPG) algorithm is optimally suitable for compressing photographs and pictures, in which realistic scenes with little contrast of colors are present.

It is also frequently used in memory cards of digital video cameras. Because of the small size it is requested by the owners of websites, allowing you to save the traffic effectively. It uses the technology of encoding of smooth color renditions, providing the ability to reduce the amount of data frequently during the recording of the image. JPEG (JPG) – is a popular graphic format, which is characterized by a high degree of compression, which leads to a decrease in image quality.
