public VolatileImage createCompatibleVolatileImage(int width, int height, int transparency, int type)

Returns a VolatileImage with specified width, height, transparency and guaranteed accelerated surface type. If such image can not be created (out of vram error, specific surface type is not supported) null is returned.

Note

if AccelSurface#TEXTURE type is requested, rendering to the image will be denied by throwing UnsupportedOperationException from java.awt.image.VolatileImage#getGraphics and java.awt.image.VolatileImage#createGraphics

Parameters
width:int

the width of the returned VolatileImage

height:int

the height of the returned VolatileImage

transparency:int

the specified transparency mode

type:int

requested accelerated surface type as specified by constants in AccelSurface interface

Returns:VolatileImage

a VolatileImage backed up by requested accelerated surface type or null
