Overview

This class is abstract.

Subclasses must implement the #convert method

Base class for conversion strategies

Conversion strategies encapsulate the logic for converting between different vector formats using external tools (Inkscape, Ghostscript, etc.)

Direct Known Subclasses

GhostscriptStrategy, InkscapeStrategy

#available? ⇒ Boolean

Check if the required external tool is available

end

#convert(content, input_format:, output_format:, **options) ⇒ String

This method is abstract.

Convert content from one format to another

Parameters:

  • content (String) —

    the input content to convert

  • input_format (Symbol) —

    the input format (e.g., :svg, :eps, :ps)

  • output_format (Symbol) —

    the desired output format (e.g., :svg, :pdf, :eps)

  • options (Hash) —

    additional options for the conversion

Returns:

  • (String) —

    the converted content

Raises:

end

#supported_conversions ⇒ Array<Array<Symbol>>

Get the list of conversions this strategy supports

Returns:

  • (Array<Array<Symbol>>) —

    array of [input, output] format pairs

#supports?(input_format, output_format) ⇒ Boolean

Check if this strategy supports the given conversion

Parameters:

  • input_format (Symbol) —

    the input format

  • output_format (Symbol) —

    the output format

Returns:

  • (Boolean) —

    true if this strategy supports the conversion

end

#tool_name ⇒ String

Get the name of the external tool used by this strategy

Returns:
