Attributes support

This document provides an overview of all SVG elements (as listed at https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute) and whether they are supported by this project. If the section for an attribute is empty, it is currently unknown whether the element is supported.

Explanation

If an attribute is supported on all elements it may be used on, the section will just say ":heavy_check_mark: Full support".
If an attribute is not supported on any element, the section will just say ":x: Not supported".
Some attributes might not be supported on all possible elements or they only accept a subset of all possible values. In this case, you will see a table like

spreadMethod

	`pad`	All other values
`<linearGradient>`	✔️ Supported	❌ Not supported
All other elements	❌ Not supported	❌ Not supported

Please note: This table only is an example for support tables. To find out the actual support for the spreadMethod-attribute, please take a look at its section.

Known bugs

All segments are translated to morph objects, but just the first of them is rendered.
Renderer expects segments to have 4 control points (see Bezier based rendering), but lines just have 2 control points.
Large arcs are split into multiple bezier curves (e.g. 4) but just the first is rendered. Might relate to (1.)

`decelerate`

❌ Not supported

`descent`

⚠️ This attribute is deprecated. It won't be supported.

`diffuseConstant`

❌ Not supported

`direction`

❌ Not supported

`display`

	`none`	`inherit`	`inline`	All other values
`<g>`, `<svg>`	Partial support (see 1.)	Partial support (see 2.)	✔️ Full support	Partial support (see 2.)
All other elements	❌ Not supported	Partial support (see 2.)	✔️ Full support	Partial support (see 2.)

Elements with display set to none should not be part of the rendering tree and should therefore not be taken into account when computing bounds. This is currently not implemented. Nevertheless, there is currently no feature that relies on the bounds of <g>s or <svg>s.
At the moment, inherit is treated like any value but none, so the element will be displayed. However, children of elements with display set to none should never be displayed, so the wrong interpretation does not cause any visible issues. On export, inherit will be exported correctly.
Will be displayed like inline which should be fine in most cases. No special features like grids are supported.

Please note

The validity of IDs is not validated. Therefore, invalid IDs may be exported if the original document contained invalid IDs. Invalid IDs include the same ID for multiple elements or IDs with invalid characters.
Although IDs can be specified and will be parsed for every element, they might not be usable for every purpose, like referencing clip paths. Please refer to the documentation of the attribute you want to supply with IDs of other elements.
