Call this method to return a new RsvgDimensionData structure. A creation function for this structure is not provided by the Rsvg API.

After calling this, you should use tolua.takeownership(rect) on the return value to ensure ownership is passed properly.

Call this method to free memory allocated by RsvgDimensionData:create.

You should call tolua.releaseownership(dd) before calling this function to avoid double-frees, but only if you previously called tolua.takeownership(dd)

Gets the values of an existing RsvgDimensionData.

Sets the values of an existing RsvgDimensionData.

Call this method to return a new RsvgRectangle structure. A creation function for this structure is not provided by the Rsvg API.

After calling this, you should use tolua.takeownership(rect) on the return value to ensure ownership is passed properly.

Call this method to free memory allocated by RsvgRectangle:create.

You should call tolua.releaseownership(rect) before calling this function to avoid double-frees, but only if you previously called tolua.takeownership(rect)

Gets the values of an existing RsvgRectangle.

Sets the values of an existing RsvgRectangle.

Call this function to return a new cairo_font_extents_t structure. A creation function for this structure is not provided by the cairo API.

After calling this, you should use tolua.takeownership(cfe) on the return value to ensure ownership is passed properly.

Call this function to free memory allocated by cairo_font_extents_t:create.

You should call tolua.releaseownership(cfe) before calling this function to avoid double-frees, but only if you previously called tolua.takeownership(cfe)

Call this function to return a new cairo_matrix_t structure. A creation function for this structure is not provided by the cairo API.

After calling this, you should use tolua.takeownership(cm) on the return value to ensure ownership is passed properly.

Call this function to free memory allocated by cairo_matrix_t:create.

You should call tolua.releaseownership(cm) before calling this function to avoid double-frees, but only if you previously called tolua.takeownership(cm)

Renders an image onto a cairo_t, using imlib2. In some cases using a cairo_t and exact coordinates is more useful.

require('cairo_imlib2_helper') in your lua file.

Call this function to return a new cairo_text_extents_t structure. A creation function for this structure is not provided by the cairo API.

After calling this, you should use tolua.takeownership(cte) on the return value to ensure ownership is passed properly.

Call this function to free memory allocated by cairo_text_extents_t:create.

You should call tolua.releaseownership(cte) before calling this function to avoid double-frees, but only if you previously called tolua.takeownership(cte)

A string containing the build architecture for this Conky instance.

A string containing build information for this Conky instance, including the version, build date, and architecture.

A string containing the path of the current Conky configuration file.

This table contains some information about Conky's internal data. The following table describes the values contained:

This function takes a string that is evaluated as per Conky's TEXT section, and then returns a string with the result.

Sets Conky's update interval (in seconds) to 'number'.

Returns the current cairo_surface_t for the active display output, or nil if no graphical surface is available. This is the preferred, backend-agnostic way to obtain a drawing surface for use with Cairo.

The returned surface is only valid for the current draw cycle. Do not cache it across frames; call conky_surface() each time your draw hook is invoked.

Example usage:

require('cairo')
function conky_draw()
  local surface = conky_surface()
  if not surface then return end
  local cr = cairo_create(surface)
  -- draw ...
  cairo_destroy(cr)
end

A string containing the version of the current Conky instance.

This table contains read-only information about Conky's window. The following table describes the values contained:

NOTE: This table is only defined when a GUI output is active. The drawable, visual, and display fields are X11-specific and deprecated.

Renders an image onto a cairo_surface_t, using imlib2. Returns the amount the image was scaled by

require('cairo_imlib2_helper') in your lua file.

Renders text to a cairo_t using HarfBuzz and FreeType. This provides significantly better text rendering than Cairo's built-in functions.

Used to calculate how many pixels will be required to render a string with cairo_text_hp_show returns a pair of int's with width and height.

cairo_text_hp_show and cairo_text_hp_text_size both cache internal font details, this function clears those caches.
