1.14. SVG filter

1.14.1. SVG filter ¶

In this tutorial, we will show only one special effect that may be used. After the presentation of the basics, you have learned to use special effects, and you should be able to apply them elsewhere. The key here is to give you an idea of how to do SVG, rather than repeating the entire specification.

The filters available for SVG are:

FeBlend-filter combined with image

FeColorMatrix-for color filter conversion

FeComponentTransfer

FeComposite

FeConvolveMatrix

FeDiffuseLighting

FeDisplacementMap

FeFlood

FeGaussianBlur

FeImage

FeMerge

FeMorphology

FeOffset-filter Shadow

FeSpecularLighting

FeTile

FeTurbulence

FeDistantLight-for lighting filtering

FePointLight-for lighting filtering

FeSpotLight-for lighting filtering

In addition, you can use multiple filters on each SVG element!

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
