Raster image formats are in the form of so-called pixel grid (colored dots).As a vector image format, it charting uses basic geometric shapes: points, splines, lines, and polygons .All vector objects are images of mathematical functions.Such an approach to the representation of the image allows you to zoom without loss of picture quality, which is not the raster graphics.Consider the most common graphics file formats.
This bitmap format is the most popular .Typically, it is used to store photos.JPG format uses a number of compression algorithms, whereby there may be a deterioration in image quality.This format is used in the development of Internet sites.In addition, modern cameras use JPG for saving pictures taken.
The PNG format is a bitmap.It uses lossless compression algorithm for Deflate , which was originally created for th
This format is obsolete, especially after the appearance of PNG.The disadvantage is that this format for storing images able to use only 256 colors .Printing will not be enough.However, a characteristic feature of the GIF format is animation support .Today, even after the advent of technology Flash, the vast World Wide Web you can find a huge number of animated banners in the format GIF.
TIFF - format for storing raster images with great color depth.This format is used to scan documents , OCR and fax .Furthermore, TIFF often used in printing.
This format uses lossless compression.He created specially for program Adobe Photoshop to support all of its features.The advantage is the ability to format PSD save layers, transparency, partial transparency and vector elements .It should be noted that the files stored in this format have a very large amount, and fully work with them using any third-party programs can not.
vector graphics file formats
Typically, each program is working with vector graphics, supports its own image format.It should also be noted that vector graphics can be two-dimensional and three-dimensional .
to work with two-dimensional graphics software package can be used Adobe Illustrator , which format to store images called AI . program CorelDRAW uses the format CDR .
As for the three-dimensional graphics, for exchange between applications developed format COLLADA .Since it can operate programs such as 3ds Max, Maya, Cinema 4D and many others.In addition, the latest version of Adobe Photoshop supports the three-dimensional graphics.
Finally it is worth noting that in this article we not all graphics file formats, and tried to tell just about the most common.In addition to these, there are formats such as BMP, ICO, MrSID, PCX, TGA, XPS, PNM, U3D, EPS, STL, X and many others.
