com.jogamp.opengl.util.awt.AWTGLPixelBuffer
public class AWTGLPixelBuffer
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.

public boolean requiresNewBuffer(GL gl, int newWidth, int newHeight, int minByteSize)
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
,
method returns allowRowStride
= falsetrue
if the new size ≠ current size.
If
, see allowRowStride
= trueAWTGLPixelBufferProvider#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
.
