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

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 GLPixelBuffer.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 requiresNewBuffer(GL, int, int, int).

Method Detail

requiresNewBuffer

public boolean requiresNewBuffer(GL gl,
                                 int newWidth,
                                 int newHeight,
                                 int minByteSize)

Returns true, if invalid or implementation requires a new buffer based on the new size due to pixel alignment or byte size, otherwise false.

It is assumed that pixelAttributes, depth and pack stays the same!

The minimum required byte size equals to minByteSize, if > 0, otherwise utilize GLBuffers.sizeof(..) to calculate it.

If allowRowStride = false, method returns true if the new size ≠ current size.

If allowRowStride = true, see AWTGLPixelBufferProvider#AWTGLPixelBufferProvider(boolean), method returns true only if the new size > current size. Assuming user utilizes the row-stride when dealing w/ the data, i.e. GL2GL3.GL_PACK_ROW_LENGTH.

Overrides:

requiresNewBuffer in class GLPixelBuffer

Parameters:

gl - the corresponding current GL context object

newWidth - new width in pixels

newHeight - new height in pixels

minByteSize - if > 0, the pre-calculated minimum byte-size for the resulting buffer, otherwise ignore.
