Package nl.colorize.multimedialib.renderer.teavm

Class TeaMediaLoader

java.lang.Object

nl.colorize.multimedialib.renderer.teavm.TeaMediaLoader

All Implemented Interfaces:

MediaLoader

public class TeaMediaLoader
extends Object
implements MediaLoader

Delegates media loading to the browser. Images, audio, and fonts are loaded using the conventional browser APIs. Text files are embedded into the HTML during the build, and can therefore be loaded immediately.

Method Details

loadImage

public Image loadImage(FilePointer file)

Description copied from interface: MediaLoader

Loads an image from a file. Images in JPEG and PNG format are supported by all renderers.

Specified by:

loadImage in interface MediaLoader

loadAudio

public Audio loadAudio(FilePointer file)

Description copied from interface: MediaLoader

Loads an audio clip from a file. MP3 files are supported by all renderers.

Description copied from interface: MediaLoader

Loads a TrueType or FreeType font so the renderer can use that font for text rendering. This will return a font for the specified style, alternative styles can be derived from the returned font.

Specified by:

loadFont in interface MediaLoader

loadModel

public PolygonModel loadModel(FilePointer file)

Description copied from interface: MediaLoader

Loads a polygon model from the specified file. Only the GLTF format is guaranteed to be supported, other file formats are only supported by specific renderers.

Specified by:

loadModel in interface MediaLoader

getGeometryBuilder

public GeometryBuilder getGeometryBuilder()

Description copied from interface: MediaLoader

Provides access to a GeometryBuilder instance that can be used to create simple 3D geometry in a programmatic way.

Specified by:

getGeometryBuilder in interface MediaLoader

loadText

public String loadText(FilePointer file)

Description copied from interface: MediaLoader

Loads a text-based resource file using UTF-8 encoding.

Specified by:

loadText in interface MediaLoader

containsResourceFile

public boolean containsResourceFile(FilePointer file)

Description copied from interface: MediaLoader

Returns whether the specified resource file is available.

Specified by:

containsResourceFile in interface MediaLoader

normalizeFilePath

protected String normalizeFilePath(FilePointer file,
 boolean replaceDot)

loadApplicationData

public Properties loadApplicationData(String appName)

Description copied from interface: MediaLoader

Loads the application data for the application with the specified name. Application data is limited to key/value properties, as this type of data is supported by all platforms. Returns an empty Properties when no application data exists.

Specified by:

loadApplicationData in interface MediaLoader

saveApplicationData

public void saveApplicationData(String appName,
 Properties data)

Description copied from interface: MediaLoader

Saves the application data for the application with the specified name. Application data is limited to key/value properties, as this type of data is supported by all platforms.

Specified by:

saveApplicationData in interface MediaLoader

getLoadStatus

public nl.colorize.util.MessageQueue<LoadStatus> getLoadStatus()

Description copied from interface: MediaLoader

Returns a buffer containing the load status of all media files that have been loaded by this MediaLoader.

Specified by:

getLoadStatus in interface MediaLoader

applyMask

public org.teavm.jso.dom.html.HTMLCanvasElement applyMask(TeaImage image,
 ColorRGB mask)

Creates an alternative version of the image with the specified mask color applied to every non-transparent pixel. This is a relatively heavy operation, so masked images are cached to avoid having to create them every single frame.
