Vector-based Image File Extension Type
SVG (Scalable
Vektor Graphics)
Is an image format that is commonly used in vector-based image formats. The advantage of SVG format images is that they look neat even though they are enlarged many times. The SVG image format is starting to be applied to web browsers such as Opera & Firefox. Vector images are expected to become the most widely used image format in the next few years.
SVG is also a new file format for displaying graphics in XML -based web development (eXtensible Mark up Language). Besides SVG, there is also XML-based MathML (Mathematics Mark up Language) for displaying mathematical formulas and also CML (Chemical Mark up Language) for chemistry. SVG serves to display 2D graphics in XML code. Basically SVG can be used to create three types of graphic objects, namely : Path (consisting of straight lines and curves), images, text. SVG can create a graphic consisting of many different vectors. And a vector is actually a line connecting 2 straight lines.
GEM (Graphics Exchange Metafile)
Is a vector-based graphic file format used by GUI-based applications (Graphical User Interface) developed by Digital Research.
CDR (Corel Draw)
Is a file format for graphics software, namely CorelDraw. This format is vector and the default format of CorelDraw. Images with .cdr extension when enlarged or reduced beyond the resolution will not be distorted or broken.
AI (Adobe Illustrator)
Is a vector-based graphic file format that is owned by adobe illustrator graphics software as the default format from the manufacturer. Images with the extension .ai when enlarged or reduced will not be distorted or broken. The file size of this format is usually large because it has not been compressed.
CGM (Computer Graphics Metafile)
Is a vector graphics file format developed by several standards organizations that is supported by many PC software products.
HPGL (Hewlett Packard Graphics Language)
It is one of the oldest file formats. While not quite as good, this format is supported by many PC-based graphics products.
PAT (Pattern File)
Is a vector-based graphic file format. This file is large, because it has not been compressed. This file is usually used to store important and quality files.
DXF (Data eXchange File)
Is a vector graphics file format developed by Autodesk. Most CAD systems can use this format.
Is a graphics file format that can contain vector graphics, text or bitmaps. An EPS file is essentially a PostScript file that meets additional restrictions. These limitations aim to make it easier for the software to embed EPS files in another PostScript document. Some PostScript EPS also support a variety of offer modes, such as RGB, Lab, CMYK, Duplex, indexed color and grayscale. In addition, EPS also reduces PostScript's ability to provide various types of fonts and text.
As a minimum, an EPS file contains a PostScript comment that is a Boundingbox in addition to the PostScript header, which describes the rectangular area where the graphic is drawn. The application program can use this information to arrange it on a page where the EPS file will be inserted, even if the program cannot render it directly.
EPS files are marked with the file extension .eps or .epsf , the latter stands for Encapsulated PostScript File i.e. the contents of the EPS file are written in plain text format so that it is a convenient format to be generated by a custom application program.
EPS files generally have a preview image of the content they contain, with the aim of displaying it on-screen. The idea is to allow a preview of the final output in each application program that can represent a bitmap. Without this preview capability application programs would have to directly render PostScript (PS) data in the EPS file, which is generally far beyond the capabilities of most machines today. When EPS was first implemented, the only types of machines that made widespread use of PostScript were Apple Macintosh machines. concerned. On a Mac machine it includes 2 files (known as a fork "fork") that are logically referenced as one piece. By placing PostScript in the "fork" and a PICT Mac Standard resource in the "fork" resource, the two images can be moved almost simultaneously. It is as if they were one file. Generally a PICT preview contains a bitmap but can also contain a vector representation of the entire image resulting in a quality preview.
PNG (Portable Network Graphics)
Is an image storage format that uses a compression method that does not remove part of the image (lossless compression). The PNG format was introduced to replace the GIF image storage format. In general, PNG is used for web images.
The PNG format has 3 advantages over the GIF format, namely: Channel Alpha (transparency), Gamma (brightness), and Progressive Display (progressive image viewing).
In addition, images with PNG format have a better compression factor than GIF (5%-25% much better than GIF format).
One feature of GIF that is not available in the PNG format is support for multi-image storage for animation purposes. For image processing purposes, even though the PNG format can be used as an alternative during the image processing process. Because this format in addition to not eliminating part of the image being processed (so that repeated storage of the image will not reduce image quality) but the JPEG format is still a better choice.
WMF (Windows Metafile Format)
Is a vector -based graphics file format for the exchange of graphics between windows applications that can also contain bitmap images. WMF also has the advantage of providing previews in vector form, but this format is rarely used.
