14.4 The Ipe style sheet format

Style sheets can either be embedded in an Ipe document, or reside in a separate file. Separate files can start with the optional <?xml> tag.

The style sheet itself consists of the single element <ipestyle>. It takes the optional attribute name, which only serves to identify the style sheet informally.

The contents of the style sheet element can consist of the following elements: template, color, dashstyle, linewidth, textsize, marksize, arrowsize, grid, angle, media.

The template element takes a required attribute name, which identifies the template and must be unique in the style sheet. Its contents is a single Ipe object.

All other elements have empty contents and two required attributes, name and value. name defines a symbolic name, value an absolute value. The symbolic name must start with a letter 'a' to 'z' or 'A' to 'Z'. The value for the color and dashstyle elements must be a legal absolute value for the Ipe object attributes of the same name. The value for linewidth, textsize, marksize, arrowsize, grid, and angle must be single real number. The value for media must be two integers (width and height in Postscript points, i.e. 1/72 inch), separated by white space.

Note that the symbolic names for grid, angle, and media cannot actually be used by objects in the document--they are only used to fill the grid size, angular snap angle, and page size selectors in the user interface with values.
