SvgType

new SvgType()

Description:

• Specifies a symbolic drawing type using a segment of the SVG specification.

  • This defines the following types:
    • svg_face which is the root type of a SVG object.
    • svg_:(face|organ|svgTag|attributes|svgD|svgSegment|coordinatesList|segmentType|transformMatrix|style|color|numeric|) which are the SVG components of a SVG object.
    • This thus does NOT define the whole SVG specification.
  • Conversion from SVG files to JSON files is performed via the Javascript utilities:
    • [.../svg2json.js < file.svg > file.json](./global.html#svg2json) outputing a file.json JSON file.
    • [.../json2svg.js < file.json > file.svg](./global.html#json2svg) outputing a file.svg SVG file.
  • An example of visual morphing is available on this demo page, using a command that generates a file1-file2.html file showing a sequence of intermediate images between file1 and file2:
    • cd .../visualmorphing ; [make](https://gitlab.inria.fr/line/aide-group/symbolingtype/-/blob/main/public/visualmorphing/makefile) [build|rebuild] i1=file1.svg i2=file2.svg
  • The utilities imagemagick convert for SVG image conversion and gifsicle for GIF animation generation are also used at the application level.

  Extending the SVG symboling subset

  • If a .svg file is not compliant with this SVG segment an unknown type error will be detected. In that case:

    • The SvgType.cpp is to be upgraded.
    • The json2svg.js and svg2json.js may have to be upgraded if new SVG compound types are encountered, i.e. string types corresponding to a record of atomic values.
