Browser config:

Firefox via about:config -> privacy.file_unique_origin = false

|
|
|
|
|
|
ToDo:
|
|
|
|
|
- adjust width and height (give options)
|
|
|
|
|
- embed config buttons inside html to adjust time/type/... (more flexible than clicking from Inkscape)
|
|
|
|
|
- we should do it the way like vivus instant -> http://maxwellito.github.io/vivus / https://maxwellito.github.io/vivus-instant
|
|
|
|
|
- the generated SVGs can be downloaded again and include all animations!
|
|
|
|
|
- calculate the total length of all paths and auto-adjust the speed to have good visibility
|
|
|
|
|
- Possible feature request could be to handle "animate selected objects only". See "Export selection as ... " extension to steal that code.
