SVG (.svg, .svgz)

  • Import supports SVG Version 2.
  • Export supports SVG Versions 1.0 and 1.1.
  • The Wolfram Language exports static SVG graphics.

Background & Context

    • MIME type: image/svg+xml
    • SVG vector graphics format.
    • Intended for two-dimensional vector graphics on the web.
    • Partially supported by several web browsers and browser plugins.
    • SVG is an acronym for Scalable Vector Graphics.
    • XML-based text format.
    • Can represent static and animated graphics.
    • Supports RGB color with an optional alpha channel.
    • Developed by the W3C SVG Working Group since 1998.

Import & Export

  • Import["file.svg"] imports an SVG file, returning a rasterized image.
  • Import["file.svg",elem] imports the specified element from an SVG file.
  • The import format can be specified with Import["file","SVG"] or Import["file",{"SVG",elem,…}].
  • Export["file.svg",expr] exports text or vector graphics to SVG.
  • Export["file.svg",expr,elem] creates an SVG file by treating expr as specifying element elem.
  • The export format can be explicitly specified with the command Export["file",expr,"SVG"].
  • See the following reference pages for full general information:
  • Import, Exportimport from or export to a file
    CloudImport, CloudExportimport from or export to a cloud object
    ImportString, ExportStringimport from or export to a string
    ImportByteArray, ExportByteArrayimport from or export to a byte array

Import Elements

  • General Import elements:
  • "Elements" list of elements and options available in this file
    "Rules"list of rules for all available elements
    "Summary"summary of properties
  • Data representation elements:
  • "Image"Image object representing the SVG file
    "Graphics"Graphics object representing the SVG file
  • Metadata elements:
  • "Dimensions"default width and height
    "XMLMetaInformation"metadata given as an XMLElement

Export Elements

  • Data representation element:
  • "Graphics"arbitrary 2D graphics
  • Export uses the "Graphics" element by default.

Basic Examples  (3)

Import an SVG file as an image:

Wolfram Language code: Import["ExampleData/spikey.svg"]

Summary of an SVG file:

Wolfram Language code: Import["ExampleData/spikey.svg", "Summary"]

Export vector graphics to SVG:

Wolfram Language code: Graphics[{Opacity[0.5], Blue, Disk[], Yellow, Disk[{1, 0}]}]
Wolfram Language code: Export["disks.svg", %]

Scope  (5)

Import  (2)

Import an SVG as an image:

Wolfram Language code: Import["ExampleData/spikey.svg", "Image"]
Wolfram Language code: Head[%]

Import an SVG as a vector graphic:

Wolfram Language code: Import["ExampleData/spikey.svg", "Graphics"]
Wolfram Language code: Head[%]

Export  (3)

Export formatted text to SVG:

Wolfram Language code: Export["lorem.svg", "Lorem ipsum *dolor* sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et *dolore* magna aliqua."]

Export a function plot to SVG:

Wolfram Language code: Export["plot.svg", [image]]

Show SVG data created by the Wolfram Language:

Wolfram Language code: ExportString[Graphics[{Red, Disk[]}], "SVG"]

Import Elements  (6)

Available Elements  (1)

List of available elements:

Wolfram Language code: Import["ExampleData/spikey.svg", "Elements"]

Data Representation  (2)

"Graphics"  (1)

Import as vector graphics:

Wolfram Language code: g = Import["ExampleData/spikey.svg", "Graphics"]
Wolfram Language code: Head[g]

Render at a higher resolution:

Wolfram Language code: Image[ImageTake[Rasterize[g, RasterSize -> 1000], {250, 500}, {250, 500}], ImageResolution -> 72]

"Image"  (1)

Import an image:

Wolfram Language code: i = Import["ExampleData/spikey.svg", "Image", ImageResolution -> 144]
Wolfram Language code: Information[i]

Rendering at a higher resolution may result in pixelation:

Wolfram Language code: ImageTake[ImageResize[i, 1000], {250, 500}, {250, 500}]

Metadata  (3)

"Dimensions"  (1)

Import the dimensions of an SVG file:

Wolfram Language code: Import["ExampleData/spikey.svg", "Dimensions"]

"MetaInformation"  (1)

Import an association of metadata in an SVG file:

Wolfram Language code: Import["ExampleData/spikey.svg", "XMLMetaInformation"]

"Summary"  (1)

Import a brief summary of an SVG file:

Wolfram Language code: Import["ExampleData/spikey.svg", "Summary"]

Import Options  (3)

ImageResolution  (1)

Import the SVG with a resolution suitable for FHD screens:

Wolfram Language code: Import["ExampleData/spikey.svg", "Image", ImageResolution -> 72]//ImageDimensions

Import the SVG with a resolution suitable for HiDPI screens:

Wolfram Language code: Import["ExampleData/spikey.svg", "Image", ImageResolution -> 144]//ImageDimensions

ImageSize  (1)

Import the SVG with a specific displayed image size:

Wolfram Language code: img = Import["ExampleData/spikey.svg", "Image", ImageSize -> 100]

Check the displayed image size:

Wolfram Language code: Options[img]

RasterSize  (1)

Render a very small image from the SVG:

Wolfram Language code: Import["ExampleData/spikey.svg", "Image", RasterSize -> 100]

Check pixel dimensions:

Wolfram Language code: ImageDimensions[%]

Render a larger image from the SVG:

Wolfram Language code: Import["ExampleData/spikey.svg", "Image", "RasterSize" -> 200]

Check pixel dimensions:

Wolfram Language code: ImageDimensions[%]
