This article will explain in detail about the format of vector pictures in the computer. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The formats of vector images are: cdr, ai, wmf, eps, bw, col, emf, iff, lbm, mag, msk, opt, ply, pbm, pcd, pcx, pict, svg, tga, win, raw, ras, dwg, dxb and so on.

The operating environment of this tutorial: windows10 system, Dell G3 computer.

A vector graph, also known as an object-oriented image or drawing image, is mathematically defined as a series of lines connected by points. The graphic elements in a vector file are called objects. Each object is a self-contained entity with attributes such as color, shape, outline, size, and screen position.

Vector graphics are drawn according to geometric characteristics, vectors can be a point or a line, vector images can only be generated by software, and files take up less internal space, because this type of image file contains independent separate images. can be reassembled freely and without restriction. Its characteristic is that the enlarged image will not be distorted and has nothing to do with resolution, so it is suitable for graphic design, text design, some logo design, layout design and so on.

Advantages

The file is small, and the information of lines and blocks is saved in the image, so the vector graphics file has nothing to do with the resolution and image size, but only related to the complexity of the image.

The image can be scaled infinitely, and when the graphics are scaled, rotated or deformed, the graphics will not produce aliasing effect.

High-resolution printing can be adopted, and vector graphics files can be printed on any output device printer at the highest resolution of printing or printing.

The biggest disadvantage is that it is difficult to show the realistic image effect with rich color levels.

The effect of vector map and bitmap is very different, vector map is infinitely enlarged and not blurred, most bitmaps are derived from vectors, it can also be said that vector map is the source code of bitmap, the source code can be edited.

Common formats of vector pictures

.bw

It is a black-and-white graphics file format that contains various pixel information.

.ai (Illustrator)

It is a kind of graphic file format in Illustrator, that is, the vector file format generated by Illustrator software, which can be opened, edited, modified and so on with Illustrator, CorelDraw, Photoshop and so on.

.cdr (CorelDraw)

It is a graphics file format in CorelDraw and a graphic image file format that can be used in all CorelDraw applications.

.col (Color Map File)

It is a palette file format created by Autodesk Animator, Autodesk Animator Pro, and other programs, which stores the RGB values of various items in the palette.

CGM (Computer Graphics Metafile) is the abbreviation of computer image file. CGM is a graphic format defined by the ISO Committee (International standard ISO/IEC 8632 International standard ISO/IEC 1999), which is used to describe, store and transmit device-independent vectors (vectors), scalars, and mixed images.

.dwg, a graphics file format used in AutoCAD.

.dxb (drawing interchange binary), a graphics file format created by AutoCAD.

.dxf (Autodesk Drawing Exchange Format), which is a graphic file format in AutoCAD, stores graphics in ASCII mode, is very accurate in showing the size of graphics, and can be called and edited by CorelDraw, 3DS and other large software.

.wmf (Windows Metafile Format)

WMF is a common metafile format in Microsoft Windows, which has the characteristics of short file and pattern-making. The whole figure is often spliced by independent components, but its graphics are often rough and can only be edited in Microsoft Office.

.emf (Enhanced MetaFile)

EMF is a Windows 32-bit extended metafile format developed by Microsoft. The overall design goal is to make up for the shortcomings of the * .wmf file format used in Microsoft Windows 3.1 (Win16) and to make metafiles easier to use.

.eps (Encapsulated PostScript)

EPS is an ASCII graphics file format described in PostScript language. It can print high-quality graphics images on PostScript graphics printers and can represent 32-bit graphics images at most. The format is divided into PhotoShop EPS format (Adobe Illustrator Eps) and standard EPS format, in which the standard EPS format can be divided into graphic format and image format. It is worth noting that only EPS files in image format can be opened in PhotoShop.

The .eps format consists of two parts: the first part is a low-resolution image displayed on the screen, which is convenient for previewing and positioning during image processing; the second part contains separate data for each color separation. The .eps file is stored in the form of D CS/CMYK, which contains separate information of the four colors of CMYK, and can directly output four-color screen. However, in addition to being more reliable on PostScript printers,

The .eps format still has many shortcomings: first, the image storage efficiency of the * .eps format is particularly low; secondly, the compression scheme of the * .eps format is also poor, generally the same image after LZW compression of * .tiff is 3 to 4 times smaller than the image of * .eps.

.ico (Icon file), which is the icon file format for Windows.

.iff (Image File Format) is a graphics file format used on super graphics processing platforms such as Amiga. Hollywood special effects blockbusters mostly use this format to reproduce the original scene realistically. Of course, this format consumes a lot of computer resources such as memory and external memory.

.lbm, a graphics file format used in Deluxe Paint, is encoded in a manner similar to * .iff.

.mag is a common graphics file format used by the Japanese.

.Mac (Macintosh) is a grayscale graphics file format used in Macintosh. When used in Macintosh paintbrush, the resolution can only be 720 × 567.

.mpt (Macintosh Paintbrush) is a graphics file format used in Macintosh.

MSK (Mask Data File), a graphics file format in Animator Pro that contains a bitmap graphic.

.opt / * .twe

.opt (Optics Menu Settings File) * .twe (Tween Data File) is a graphics file format created by Animator Pro.

.ply (Polygon File) is a graphics file format created by Animator Pro that contains information about a series of points used to describe polygons.

.pbm / * .pgm / * .ppm, (Portable Pixmap) drawing file format.

.pcd (Kodak PhotoCD), a PhotoCD file format developed by Kodak, can only be read by other software systems. This format is mainly used to store color scanned images on CD-ROM, and it uses YCC color mode to define the colors in the image.

.pcx (PC Paintbrush) / * .pcc is a compressed PC bitmap file format supported by Zsoft's PC Paintbrush graphics software. Later, Microsoft transplanted PC Paintbrush to Windows environment, and the * .pcx image format was supported by more graphics and image processing software. The number of colors supported by this format has grown from 16 colors to 16.77 million colors. It uses a run-length coding scheme for compression with a 128-byte header.

.pic, a graphics file format that contains uncompressed image information.

.pict / .pict2 / .pnt

The .pict file format is mainly used on Macs and can also be used on PCs with Quick Time installed. Files in this format are not suitable for printing (printing files in * .pict format on PostScript printers will cause PostSlipt errors) and are often used in multimedia projects. * .pict is also one of the formats used by Mac applications for image display.

.pdd, like .psd, is a dedicated graphics file format in PhotoShop software that saves every small portion of image data, including layers, additional mask channels, and other content that will be lost when transferred to other formats. In addition, because these two formats are native files supported by PhotoShop, PhotoShop can open and store them faster than other formats. Unfortunately, although PhotoShop uses compression techniques in the calculation process, the image files stored in these two formats are still very large. However, storing images in these two formats will not cause any data loss, so when you are in the editing process, it is best to choose these two formats to save the disk, and then convert to other file formats that take up less disk space and better storage quality.

.pxr (PiXaR), perhaps only PIXAR workstation users are familiar with the file format * .pxr, which supports grayscale images and RGB color images. You can open a * .pxr image created by a PIXAR workstation in PhotoShop, or you can save the image file in * .pxr format for transmission to the workstation.

.ras / .raw

Ras (Sun Raster files) / .raw (Raw GrayScale) graphics file format.

Scitex CT

Scitex CT is an image file format created on Scitex high-grade prepress workstation, which is mainly used for image editing and color separation. Scitex CT images are always opened in CMYK mode, so keep their CMYK mode if they eventually return to the Scitex system. You can use PhotoShop to open and edit Scitex CT images.

.svg scalable vector graphics (Scalable Vector Graphics)

.tga (Tagged Graphic)

TGA is an image file format developed by True Vision for its display card. it was created earlier and the highest number of colors can reach 32 bits, including 8-bit Alpha channels for displaying live televisions. This format has been widely used in various fields of PC, and this format file makes it possible for Windows and 3DS to exchange image files. You can first generate colorful * .tga files in 3DS, and then modify and render them in Win dows using applications such as Photoshop, Freeherd, Painter and so on.

.win, is a graphics file format similar to * .tga.

.xbm (X BitMap), is a graphics file format.
