Instance Method Details

#create_tile(x, y, z) ⇒ Gegl::Tile

Create a new tile associated with this tile handler.

Parameters:

• x (Integer) —

  The tile space x coordinate for the tile

• y (Integer) —

  The tile space y coordinate for the tile

• z (Integer) —

  The tile space z coordinate for the tile

Returns:

• (Gegl::Tile) —

  the new tile

#damage_rect(rect) ⇒ nil

Parameters:

• rect (Gegl::Rectangle)

Returns:

• (nil)

#damage_tile(x, y, z, damage) ⇒ nil

Parameters:

• x (Integer)
• y (Integer)
• z (Integer)
• damage (Integer)

Returns:

• (nil)

#dup_tile(tile, x, y, z) ⇒ Gegl::Tile

Create a duplicate of tile, associated with this tile handler.

Parameters:

• tile (Gegl::Tile) —

  the Gegl::Tile to copy

• x (Integer) —

  The tile space x coordinate for the tile

• y (Integer) —

  The tile space y coordinate for the tile

• z (Integer) —

  The tile space z coordinate for the tile

Returns:

• (Gegl::Tile) —

  the new tile

#get_source_tile(x, y, z, preserve_data) ⇒ Gegl::Tile

Fetches the tile at the given coordinates from handler source. If the tile doesn't exist, or if handler doesn't have a source, creates a new tile associated with this tile handler.

If preserve_data is FALSE, the tile contents are unspecified.

Parameters:

• x (Integer) —

  The tile space x coordinate for the tile

• y (Integer) —

  The tile space y coordinate for the tile

• z (Integer) —

  The tile space z coordinate for the tile

• preserve_data (Boolean) —

  whether existing tile data should be preserved

Returns:

• (Gegl::Tile) —

  the tile

#get_tile(x, y, z, preserve_data) ⇒ Gegl::Tile

Fetches the tile at the given coordinates from handler. If the tile doesn't exist, creates a new tile associated with this tile handler.

If preserve_data is FALSE, the tile contents are unspecified.

Parameters:

• x (Integer) —

  The tile space x coordinate for the tile

• y (Integer) —

  The tile space y coordinate for the tile

• z (Integer) —

  The tile space z coordinate for the tile

• preserve_data (Boolean) —

  whether existing tile data should be preserved

Returns:

• (Gegl::Tile) —

  the tile

#lock ⇒ nil

Returns:

• (nil)

#source ⇒ GObject::Object

Returns source.

Returns:

• (GObject::Object) —

  source

#source=(source) ⇒ GObject::Object

Parameters:

• source (GObject::Object)

Returns:

• (GObject::Object) —

  source

• (GObject::Object) —

  source

#unlock ⇒ nil

Returns:

• (nil)
