1·It is primarily a vector graphics language, though some raster graphics features are available.
它主要是一种矢量图形语言，但是可以使用某些光栅图形特性。
2·Taking a 10-meter-by-10-meter grid and making one observation for each intersection (100 observations) would constitute a raster dataset.
比如 10 米乘 10 米的网格，取每个交叉点的值（共有 100 组）就形成一个光栅数据集。
3·Elevation data is a good example of a single-band raster dataset, often visualized with a color ramp, as shown in Figure 2.
高程数据就是很好的单级光栅数据的例子，它经常用颜色坡度，如图2所示。
4·SVG's feature set includes nested transformations, clipping paths, alpha masks, raster filter effects, template objects, and of course extensibility.
SVG的特性包括：嵌套转换、剪辑路径、alpha蒙板、光栅过滤效果、模板对象，当然还有可扩展性。
