Takes the source buffered image and converts it to a buffered image which is backed by a direct byte buffer

Parameters:

source -

Returns:

the DirectBufferedImage

makeDirectImageRGBA

public static DirectBufferedImage makeDirectImageRGBA(java.awt.image.BufferedImage source)

takes the source buffered image and converts it to a buffered image which is backed by a direct byte buffer

Parameters:

source -

make

public static DirectBufferedImage make(java.awt.image.BufferedImage bi)

make

public static DirectBufferedImage make(java.awt.image.BufferedImage bi,
                                       boolean expectAlpha)

reads in an image using image io. It then detects if this is a RGBA or RGB image and converts it to the appropriate direct image. Unfortunly this does mean we are loading a buffered image which is thrown away, but there is no help for that currently.

Parameters:

name -

Throws:

java.io.IOException
