Method Detail

setAntialiasing

public void setAntialiasing(boolean set)

getBackingStore

public TextImageStore getBackingStore()

Backing storage so that characters can be uploaded. All updates should be done through the backing store.

Returns:

backing store

getWidth

public int getWidth()

Description copied from interface: TextureContent

Number of pixels across width in content

Specified by:

getWidth in interface TextureContent

Returns:

number of pixels

getHeight

public int getHeight()

Description copied from interface: TextureContent

Number of pixels across height in content

Specified by:

getHeight in interface TextureContent

Returns:

number of pixels

getPixelSize

public int getPixelSize()

Description copied from interface: TextureContent

Size of pixels in bytes

Specified by:

getPixelSize in interface TextureContent

Returns:

size

getData

public void getData(java.nio.ByteBuffer out)

Description copied from interface: TextureContent

Get raw byte data of content, rasterized in row-major form, with (0,0) in the bottom-left corner.

Specified by:

getData in interface TextureContent

getData

public void getData(Rectangle rect,
                    java.nio.ByteBuffer out)

Description copied from interface: TextureContent

Get raw byte data for a region, rasterized in row-major form with (0,0) in the bottom-left corner.

Specified by:

getData in interface TextureContent

Parameters:

rect - rectangular region to acquire data for

out - buffer to fill

getDirty

public Rectangle getDirty()

Description copied from interface: TextureContent

The portion of the texture that has been modified (marked "dirty")

Specified by:

getDirty in interface TextureContent

Returns:

bounding region of dirty area, null if nothing marked as dirty

isDirty

public boolean isDirty()

Description copied from interface: TextureContent

All or part of the texture has been marked as "dirty" (i.e. updated)

Specified by:

isDirty in interface TextureContent

markClean

public void markClean()

Description copied from interface: TextureContent

Mark the entire texture as being clean

Specified by:

markClean in interface TextureContent

getKey

public java.lang.Object getKey()

Description copied from interface: TextureContent

A key for referring to this texture. If two contents have the same key, then it is assumed they have the same underlying data (e.g. a filename, if loaded directly from a file). The key should be immutable (at least from a hashcode/equals perspective)

Specified by:

getKey in interface TextureContent

Returns:

uniquely identifying key

getFormat

public TextureContent.ContentFormat getFormat()

Description copied from interface: TextureContent

Format of data returned by TextureContent.getData(java.nio.ByteBuffer)

Specified by:

getFormat in interface TextureContent

Returns:

format of data in buffer

See Also:

TextureContent.getData(java.nio.ByteBuffer)

acquire

public TextureContentText acquire()

Description copied from interface: ReferenceCounted

Signal the resource that something is holding a reference to it.

Specified by:

acquire in interface TextureContent

Specified by:

acquire in interface ReferenceCounted

Overrides:

acquire in class ReferenceCountedBase

Returns:

a reference to the acquired object for convenience.
