矢量图像是一个收集个人的物体，而不是画面元素。 A vector image can be composed of points connected by lines, or nodes (control points) connected by Bezier curves.矢量图像可以组成点连接线，或节点（控制点）的连接， bezier曲线。

Vector Images: Advantages

用通俗的话语来说 就是矢量图像最大的特点是不易失真 而缺点是 容量大 易损坏 颜色单调

矢量图像：优势

Each individual object contained in a vector image is defined by a mathematical equation.每个对象包含在矢量图像是指由一个数学方程。 This means that vector images are not resolution dependent.这意味着载体的影像并不是第依赖性。 Thus, each vector object is scalable and can generally be resized without any loss of image quality.因此，每个矢量对象是可扩展性和大致可resized没有任何损失的图像质量。 As such, vector images are ideal for graphics such as maps and company logos that often require scaling.这样，矢量图像，非常适合图形如地图和公司标识，往往需要缩放。 However, it must be noted that when the sizes of some vector images are reduced too drastically, fine lines may disappear.但是，必须指出的是，当尺寸有些矢量图像，减少过于急剧，细纹可能就此消失。 Too much enlargement can also make drawing mistakes apparent.太多的扩大也可以借鉴失误明显。

Each individual object may be edited to contain attributes such as outline, color and fill.每个对象可编辑包含属性，例如大纲，颜色和填土。 Modifying the object's attributes will not change the basic object.修改对象的属性是不会改变的基本对象。 The size of the object can also be transformed or shaped by using and adjusting its control points.大小的物体也可以被改造或塑造出来的使用和调整其控制点。

Vector images have no white pixel backgrounds.矢量图像有没有白纸像素的背景。 This means that you can put a vector object above another without blocking out the object underneath.这意味着你可以把一个向量对象上面又没有堵出物体底下。

Vector images typically have small file sizes because one such file contains only the mathematical equations that determine the Bezier curves that define the image.矢量图像通常有文件较小，因为这样一个文件包含只有数学方程决定bezier曲线界定形象。 A vector image file does not contain the image itself.矢量图像文件不包含图像本身。

Vector Images: Disadvantages

矢量图像：缺点

Vector images, though they are highly defined, are not appropriate for use in producing realistic-looking photos and images.矢量图像，虽然他们是非常确定的，并不适合用在生产实际看照片和图像。 Vector images have solid color and gradient attributes but they are not conducive to uninterrupted sequences of subtle color tone and shade variations.矢量图像有深厚的色彩和梯度属性，但它们是不利于不间断序列的微妙色调明暗变化。

There have been improvements to vector drawing software which enables users to approximate photorealistic vector objects.有改进的矢量绘图软件，使用户能够近似真实感矢量对象。 Attributes such as transparency can now be adjusted using vector imaging tools.属性，如透明，现在可以调整使用矢量成像工具。 Bitmap textures can now also be applied to vector objects.位图纹理，现在也可以应用于矢量对象。 Shading and blending are also some of the new vector imaging tools' functionalities.遮荫和交融，也有一些的新载体成像工具的功能。 Still, most vector images look like sharply drawn cartoon images.尽管如此，美国多数矢量图像样子急剧得出的卡通形象。

Working with Vector Images

工作与矢量图像

Vector images can be made through vector imaging software such as Adobe Illustrator, Corel Draw and Macromedia Freehand among others.矢量图像可通过矢量成像软件如adobe插画， corel draw和macromedia的徒手画等。 You can also scan pictures and graphics then convert it to vector images by using vector conversion software.您也可以扫描照片和图表，然后转换为矢量图像采用矢量转换软件。

Vector images can be converted to bitmap images.矢量图像可以转换为位图图像。 Save the vector image first then specify the output bitmap image's resolution through the rasterizing process.拯救矢量图像，然后先指定输出位图图象的决议，通过生成的过程。 Pixel size, anti-aliasing and dithering of the output bitmap image are determined through this process.像素大小，抗锯齿和抖动的输出，位图图像有决心通过这个过程。 After conversion, it is best to save it in GIF or PNG formats if the resulting bitmap image is going to be used in the Web.经过换算，它是最好的挽救它在gif或png格式，如果由此产生的位图图像，是要用来在网站上。

Vector Images Formats

矢量图像格式

There are various file formats for saving vector images.有各种档案格式为节省矢量图像。 EPS or Encapsulated PostScript format is the most versatile vector file format and is thus the most commonly used. eps或压缩的postscript格式，是最多才多艺的矢量文件格式，并因此是最常用的。 Another widely used vector image file format is PDF or Portable Document Format that was developed by Adobe.另一种广泛使用的矢量图像文件格式是pdf或可携式文件格式，是由上市销售。 One other file format for saving vector images is PICT which was developed by Macintosh.另一项文件格式为节省矢量图像pict ，这是由麦金塔。

矢量地图被广泛地运用于地理信息系统、移动信息服务、移动计算、车辆导航、网络制图等研究和应用中。矢量地图的存储尤其是大比例尺矢量电子地图的存储对于提高移动终端的数据存储量、加快矢量地图的绘制速度、减少网络传输时间具有十分重要的作用。
