Units support

The library support the following length and position units^[1]

See Coordinate Systems, Transformations and Units

:

• The px, pt, in, cm, mm, em, and ex units
• The % unit

Behavior for the non relative units

• The computation for the ex unit is an approximation, considering one 1/2 of the em unit
• The computation for the em unit does not take inot account for the moment the height of the fonts

Behavior for the % unit

The "%" unit specifies a length or a position relative to the viewport. The library works in the following way:

• If the with and height attributes are present in the SVG root, they are used to specify the dimensions of the viewport
• Else if the viewBox attribute is present, it will be used to get the width and height of the viewport

Limitations

The path element does not currently support the "%" unit.
