## Description

A renderer is used to render tiles textures. A tile is rendered based on the provided data - this can be arbitrary data the given renderer understands (e.g. raw bitmap data, vector xml map representation and so on).

## Functions

### champlain_renderer_set_data ()

    void
    champlain_renderer_set_data (ChamplainRenderer *renderer,
                                 const gchar *data,
                                 guint size);

Sets the data which is used to render tiles by the renderer.

#### Parameters

renderer | a ChamplainRenderer |
data | data used for tile rendering |
size | size of the data in bytes |

Since 0.8

### champlain_renderer_render ()

    void
    champlain_renderer_render (ChamplainRenderer *renderer,
                               ChamplainTile *tile);

Renders the texture for the provided tile and calls `champlain_tile_set_content()` to set the content of the tile. When the rendering is finished, the renderer emits the “render-complete” signal. The tile has to be displayed manually by calling `champlain_tile_display_content()`.

#### Parameters

renderer | a ChamplainRenderer |
tile | the tile to render |

Since 0.8

## Types and Values

### struct ChamplainRenderer

    struct ChamplainRenderer;

The ChamplainRenderer structure contains only private data and should be accessed using the provided API
