Method Detail

getDisplayByteBuffer

public java.nio.ByteBuffer getDisplayByteBuffer()

Obtains RGB data of the screen in the form of ByteBuffer.
Warning: If the window is disabled, will just return a black buffer.

Returns:

the RGB data of the screen in the form of ByteBuffer

getDisplayByteBufferAsBytes

public byte[] getDisplayByteBufferAsBytes()

Obtains RGB data of the screen in the form of byte[].
Warning: If the window is disabled, will just return a black buffer.

the RGB data of the screen in the form of byte[]

getDisplayByteBufferAsBytes

public byte[] getDisplayByteBufferAsBytes(int newWidth,
                                          int newHeight,
                                          boolean grayScale)

Obtains RGB data or the grayScale data of the screen in the form of byte[].
Warning: This method doesn't return exactly the same buffer as getDisplayByteBufferAsBytes().

Parameters:

newWidth - the width in pixel for the scaled image

newHeight - the height in pixel for the scaled image

grayScale - true to use grayScale for the scaled image (1 byte per pixel instead of 3 bytes per pixel with RGB)
