It is also very easy to convert from vector to raster formats, but the same ease doesn't hold true vice-versa.
将矢量图转换为光栅图也很简单，可反过来则不行。
Vector data require far less storage than raster data because arc node lists simplify and reduce the data required to make sense of the features contained in the map.
矢量数据要求的存储要比栅格数据少得多，因为弧节点列表简化并减少了表示地图中包含的特征所需的数据。
Vector images can be blown up to any size without loss of quality. Raster (or Bitmap) images become jagged when made larger.
矢量图无论放大多少都不会损失图片质量，而光栅图(或位图)一旦放大就会出现锯齿。
Layers of raster data are more often called bands, although the term layer still applies to raster as well as vector data.
光栅数据的层通常称为段，而术语层仍然用于光栅和矢量数据。
The SOCET GXP v3.2 software release also adds automated tools for viewing and editing live video feeds, and efficient tools for converting terrain analysis results from raster to vector file format.
该SOCETGXPV3.2软件还增加了用于查看和编辑实况视频的自动化工具和用于转换地形分析结果(从栅格转为矢量文件格式)的高效工具。
Laser systems can work with either color or grey-scale vector or raster images, however some manufacturers can require you to work with proprietary software.
激光系统可以应用于彩色、灰度矢量或光栅图像工作，然而大部分的制造商则一直在使用特定的软件进行工作。
Instead of assigning colors to pixels as we do in raster graphics, a vector-graphics format describe an image in terms of lines and geometric shapes.
矢量图形格式不像光栅图形那样把颜色赋予像素，而是用线段活几何形状描述图像。
The merging of raster and vector image can be carried out by creating WORLD file relevant to the raster image.
通过创建与栅格图像相对应的WORLD文件，可以实现栅格图像与矢量图的融合。

The algorithm of transferring vector polygon to raster data is one of the basic algorithms of GIS.
矢量多边形的栅格化算法是地理信息系统的基础算法之一。
The drawing mode is for raster devices only; it does not apply to vector devices.
绘图模式仅用于光栅装置；它不用于向量装置。
There are times when working with vector images is what's called for. Of course, there are also times (like photography) when you have to go with raster images.
写本文是出于，有的工作中偶尔会需要用到矢量图，当然有时也需要用到光栅图(比如摄影)。
