Field Detail

NONE

public static final ImageType NONE

Deprecated.

The enum for layers not backed by any offscreen buffer.

VOLATILE

public static final ImageType VOLATILE

Deprecated.

The enum for offscreen buffer backed by a VolatileImage. NOTE: Transparency is not yet implemented in current VolatileImage API. Consequently, setting offscreen buffering for layers other than the base map will hide previously rendered layers. Transparency in volatile image is scheduled for a future J2SE version. See 4881082 in Sun's RFE database.

BUFFERED

public static final ImageType BUFFERED

Deprecated.

The enum for offscreen buffer backed by a BufferedImage. At the difference of VOLATILE, buffered image supports transparency. It may be more appropriate for layer above the base map.
