cairo_tag_begin.RdMarks the beginning of the tag_name structure. Call cairo_tag_end() with the same tag_name to mark the end of the structure.
cairo_tag_begin(cr, tag_name, attributes)
| cr | [ |
|---|---|
| tag_name | [ |
| attributes | [ |
The attributes string is of the form "key1=value2 key2=value2 ...". Values may be boolean (true/false or 1/0), integer, float, string, or an array.
String values are enclosed in single quotes ('). Single quotes and backslashes inside the string should be escaped with a backslash.
Boolean values may be set to true by only specifying the key. eg the attribute string "key" is the equivalent to "key=true".
Arrays are enclosed in '[]'. eg "rect=[1.2 4.3 2.0 3.0]".
If no attributes are required, attributes can be an empty string or NULL.
See [Tags and Links Description][cairo-Tags-and-Links.description] for the list of tags and attributes.
Invalid nesting of tags or invalid attributes will cause cr to shutdown with a status of %CAIRO_STATUS_TAG_ERROR.
