Overview ¶
Package render can be used to render parsed map to image. Currently supports only orthogonal rendering out-of-the-box.

Variables ¶
var ( // ErrUnsupportedOrientation represents an error in the unsupported orientation for rendering. ErrUnsupportedOrientation = errors.New("tiled/render: unsupported orientation") // ErrUnsupportedRenderOrder represents an error in the unsupported order for rendering. ErrUnsupportedRenderOrder = errors.New("tiled/render: unsupported render order") // ErrOutOfBounds represents an error that the index is out of bounds ErrOutOfBounds = errors.New("tiled/render: index out of bounds") )
Functions ¶

Types ¶
type OrthogonalRendererEngine ¶
type OrthogonalRendererEngine struct {
// contains filtered or unexported fields
}
OrthogonalRendererEngine represents orthogonal rendering engine.
func (*OrthogonalRendererEngine) GetFinalImageSize ¶
func (e *OrthogonalRendererEngine) GetFinalImageSize() image.Rectangle
GetFinalImageSize returns final image size based on map data.
func (*OrthogonalRendererEngine) GetTilePosition ¶
func (e *OrthogonalRendererEngine) GetTilePosition(x, y int) image.Rectangle
GetTilePosition returns tile position in image.
func (*OrthogonalRendererEngine) Init ¶
func (e *OrthogonalRendererEngine) Init(m *tiled.Map)
Init initializes rendering engine with provided map options.
func (*OrthogonalRendererEngine) RotateTileImage ¶
func (e *OrthogonalRendererEngine) RotateTileImage(tile *tiled.LayerTile, img image.Image) image.Image
RotateTileImage rotates provided tile layer.
type Renderer ¶
type Renderer struct {
Result *image.NRGBA // The image result after rendering using the Render functions.
// contains filtered or unexported fields
}
Renderer represents an rendering engine.
func NewRenderer ¶
NewRenderer creates new rendering engine instance.
func NewRendererWithFileSystem ¶
NewRendererWithFileSystem creates new rendering engine instance with a custom file system.
func (*Renderer) Clear ¶
func (r *Renderer) Clear()
Clear clears the render result to allow for separation of layers. For example, you can render a layer, make a copy of the render, clear the renderer, and repeat for each layer in the Map.
func (*Renderer) RenderGroup ¶
RenderGroup renders single group.
func (*Renderer) RenderGroupLayer ¶
RenderGroupLayer renders single map layer in a certain group.
func (*Renderer) RenderGroupObjectGroup ¶
RenderGroupObjectGroup renders single object group in a certain group.
func (*Renderer) RenderLayer ¶
RenderLayer renders single map layer.
func (*Renderer) RenderObjectGroup ¶
RenderObjectGroup renders a single object group
func (*Renderer) RenderVisibleGroups ¶
RenderVisibleGroups renders all visible groups
func (*Renderer) RenderVisibleLayers ¶
RenderVisibleLayers renders all visible map layers.
func (*Renderer) RenderVisibleLayersAndObjectGroups ¶
RenderVisibleLayersAndObjectGroups render all layers and object groups, layer first, objectGroup second so the order may be incorrect, you may put them into different groups, then call RenderVisibleGroups
func (*Renderer) RenderVisibleObjectGroups ¶
RenderVisibleObjectGroups renders all visible object groups
func (*Renderer) SaveAsJpeg ¶
SaveAsJpeg writes rendered layers as JPEG image to provided writer.
type RendererEngine ¶
type RendererEngine interface {
Init(m *tiled.Map)
GetFinalImageSize() image.Rectangle
RotateTileImage(tile *tiled.LayerTile, img image.Image) image.Image
GetTilePosition(x, y int) image.Rectangle
}
RendererEngine is the interface implemented by objects that provide rendering engine for Tiled maps.
