The graphical format is a method of recording graphic information for storing images (photos and drawings). Image file formats there are vector and raster.

Raster formats represent an image as a pixel grid (colored dots). As for the vector image format, it to build graphics use the basic geometric shapes: points, splines, lines, and polygons{!LANG-c74dc2472417be90076f5e11a6f78580!}

JPEG (JPG)

This raster format is the most popular{!LANG-4d6d1d67c4e222cf0779229878663b66!}

The PNG format is a raster. It uses a lossless compression algorithm Deflate{!LANG-f82ef8cd4cc6cf9685633f9706d47fca!}

This format is considered obsolete, especially after the appearance of PNG. The disadvantage is that this format for storing image is able to use only 256 colors. For printing this will not be enough. However, a characteristic feature of the GIF format is animation support{!LANG-fcf79664d67262804d35419017384b92!}

TIFF – format for storing raster images with large color depth. This format is used for document scanning, OCR, and faxing. In addition, TIFF is often used in the printing industry.

This format uses a lossless compression. It is specially designed for Adobe Photoshop to support all of its features. The advantage of PSD files is the ability preserve layers, transparency, partial transparency and vector elements{!LANG-df3c3e1c1c09a6596d25157c9ea33d46!}

As a rule, every program that works with vector graphics, supports its own image format. It should also be noted that vector graphics is two-dimensional and three-dimensional .

To work with two-dimensional graphics can be used software package Adobe Illustrator. which format to save the images is called AI. CorelDRAW uses the CDR format .

As for three-dimensional graphics, for exchange between applications was developed the COLLADA format{!LANG-aa606ef733d16b59c1db29762f4fa9c3!}

Finally it is worth noting that in this article, we reviewed, not all formats of image files, and tried to tell only about the most common. In addition to these, there are such formats as BMP, ICO, MrSID, PCX, TGA, XPS, PNM, U3D, EPS, STL, X and many others.
