Import-Export > Import > SVG Import Supported Objects

The SAMLight import filter for SVG files - SVG - Scalable Vector Graphics, SCAPS (*.svg) - is based on open source SVG++.

In the following tables, different attributes and elements of SVG files are listed. For the import filter, information is given if these attributes and elements are supported or not. Additional information on specific interpretation is also given in some cases.

note

These lists are not complete due to the complexity of the SVG file format.

Recommended SVG properties and import filter options:

•Use SVG - SCAPS import filter with "Import with 96 dpi".

•Don't use viewBox to avoid scaling.

•Use elements with unit mm to get a 1:1 interpretation in SAMLight.

•Use UTF-8 coding for the SVG

Coordinates and Units	"SVG - SCAPS" Import Filter
Units	✓supported units: 'em', 'px', 'pt', 'pc', 'cm', 'mm', 'in', '%' and unitless ✗not supported: 'ex' •Unitless coordiantes are interpreted as 'px'. •If the 'Import with 96 dpi' is checked, 'px' are converted to mm with 96 dpi •If the 'Import with 96 dpi' is not checked, 'px' are converted to mm with 25.4 dpi ('px' equals 'mm').
Coordinates of Elements	✓Coordiantes of elements are scaled by a factor.

•Unitless coordiantes are interpreted as 'px'.

•If the 'Import with 96 dpi' is checked, 'px' are converted to mm with 96 dpi

•If the 'Import with 96 dpi' is not checked, 'px' are converted to mm with 25.4 dpi ('px' equals 'mm').

Attributes of SVG Element	"SVG - SCAPS" Import Filter
Namespace <xmlns>	•xmlns='http://www.w3.org/2000/svg' in SVG element is mandatory.
Viewport <width>, <height>	✓supported as reference for coordinates in '%'. •If the Viewport is not specified, a default Viewport of 100 px is set. •How the 'px' coordinates are converted to mm depends on the state of the 'Import with 96 dpi' checkbox, see table -1.
viewBox <viewBox>	✓supported for scaling and positioning. •viewBox origin shifts elements. •viewBox is unitless. How the unitless coordinates are converted to 'mm' depends on the state of the 'Import with 96 dpi' checkbox, see table -1. •In order to avoid scaling, the viewBox must not be specified or be of the same size as the Viewport.

Table 41: Attributes of SVG Element

Element Attributes	"SVG - SCAPS" Import Filter
Color of stroke and fill (for pen mapping)	✓The stroke color is used. 'Read Pen Info' must be checked. •Stroke none is treated as the default color black. •Fill color is usually ignored. Only when "import with default hatch style" is activated, elements with fill will be hatched. •If color of stroke and fill are both "none", the SVG element will not be imported at all. Default fill color is black.
CSS	✓supported
xml:space	✗not supported
Vertical alignment <dominant-baseline>	✓supported
Horizontal alignment <text-anchor>	✓supported. The text-anchor sets the horizontal alignment. •Default is used for start. •Em-Center is used for middle. •Em-Right is used for end.
<tspan>	✓supported
Font weight <font-weight>	✓partially supported •Normal is used for "lighter", "normal" and a number < 700. •Bold is used for "bold", "bolder" and a number >= 700.
Path attribute <d>	✓supported
Entity name of subgroups <id>	✓supported •"id" is used to name the sub-entities.
Transformation Matrices	✓supported
Filling	✗not supported
Stroking	✗not supported •color see above
Marker	✗not supported
Linking	✗not supported
Clipping, Masking, and Compositing	✗not supported
