Class AWTGLPixelBuffer

java.lang.Object
  com.jogamp.opengl.util.GLPixelBuffer
      com.jogamp.opengl.util.awt.AWTGLPixelBuffer

public class AWTGLPixelBuffer
extends GLPixelBuffer

AWT GLPixelBuffer backed by an BufferedImage of type BufferedImage.TYPE_INT_ARGB or BufferedImage.TYPE_INT_RGB.

Implementation uses an array backed IntBuffer.

AWTGLPixelBuffer can be produced via AWTGLPixelBuffer.AWTGLPixelBufferProvider's allocate(..).

See GLPixelBuffer.requiresNewBuffer(GL, int, int, int) for GLPixelBuffer.allowRowStride details.

If using allowRowStride == true, user may needs to get the aligned image since GLPixelBuffer.requiresNewBuffer(GL, int, int, int) will allow different width in this case.

Constructor Detail

AWTGLPixelBuffer

public AWTGLPixelBuffer(GLPixelBuffer.GLPixelAttributes pixelAttributes,
                        int width,
                        int height,
                        int depth,
                        boolean pack,
                        BufferedImage image,
                        Buffer buffer,
                        boolean allowRowStride)

Parameters:

pixelAttributes - the desired GLPixelAttributes

width - in pixels

height - in pixels

depth - in pixels

pack - true for read mode GPU -> CPU, otherwise false for write mode CPU -> GPU

image - the AWT image

buffer - the backing array

allowRowStride - If true, allow row-stride, otherwise not. See GLPixelBuffer.requiresNewBuffer(GL, int, int, int). If true, user shall decide whether to use a width-aligned image.

Method Detail

dispose

public void dispose()

Description copied from class: GLPixelBuffer

Dispose resources. See GLPixelBuffer.isValid().

Overrides:

dispose in class GLPixelBuffer

getAlignedImage

public BufferedImage getAlignedImage(int width,

Returns a width- and height-aligned image representation sharing data w/ image.

Parameters:

width -

height -

Returns:

Throws:

IllegalArgumentException - if requested size exceeds image size
