Class MipMapTextureData

java.lang.Object

com.badlogic.gdx.graphics.glutils.MipMapTextureData

All Implemented Interfaces:

TextureData

public class MipMapTextureData
extends java.lang.Object
implements TextureData

This class will load each contained TextureData to the chosen mipmap level. All the mipmap levels must be defined and cannot be null.

Constructor Detail

MipMapTextureData

public MipMapTextureData(TextureData... mipMapData)

Parameters:

mipMapData - must be != null and its length must be >= 1

Method Detail

getType

public TextureData.TextureDataType getType()

Specified by:

getType in interface TextureData

Returns:

the TextureData.TextureDataType

isPrepared

public boolean isPrepared()

Specified by:

isPrepared in interface TextureData

Returns:

whether the TextureData is prepared or not.

prepare

public void prepare()

Description copied from interface: TextureData

Prepares the TextureData for a call to TextureData.consumePixmap() or TextureData.consumeCustomData(int). This method can be called from a non OpenGL thread and should thus not interact with OpenGL.

Specified by:

prepare in interface TextureData

consumePixmap

public Pixmap consumePixmap()

Description copied from interface: TextureData

Returns the Pixmap for upload by Texture. A call to TextureData.prepare() must precede a call to this method. Any internal data structures created in TextureData.prepare() should be disposed of here.

Specified by:

consumePixmap in interface TextureData

Returns:

the pixmap.

disposePixmap

public boolean disposePixmap()

Specified by:

disposePixmap in interface TextureData

Returns:

whether the caller of TextureData.consumePixmap() should dispose the Pixmap returned by TextureData.consumePixmap()

consumeCustomData

public void consumeCustomData(int target)

Description copied from interface: TextureData

Uploads the pixel data to the OpenGL ES texture. The caller must bind an OpenGL ES texture. A call to TextureData.prepare() must preceed a call to this method. Any internal data structures created in TextureData.prepare() should be disposed of here.

Specified by:

consumeCustomData in interface TextureData

getWidth

public int getWidth()

Specified by:

getWidth in interface TextureData

Returns:

the width of the pixel data

getHeight

public int getHeight()

Specified by:

getHeight in interface TextureData

Returns:

the height of the pixel data

getFormat

public Pixmap.Format getFormat()

Specified by:

getFormat in interface TextureData

Returns:

the Pixmap.Format of the pixel data

useMipMaps

public boolean useMipMaps()

Specified by:

useMipMaps in interface TextureData

Returns:

whether to generate mipmaps or not.

isManaged

public boolean isManaged()

Specified by:

isManaged in interface TextureData

Returns:

whether this implementation can cope with a EGL context loss.
