Interface GLPixelBuffer.GLPixelBufferProvider

Method Details

• getAllowRowStride

  boolean getAllowRowStride()

  Allow GL2ES3.GL_PACK_ROW_LENGTH, or GL2ES2.GL_UNPACK_ROW_LENGTH.

• getAttributes

  GLPixelBuffer.GLPixelAttributes getAttributes(GL gl, int componentCount, boolean pack)

  Returns RGB[A] GLPixelBuffer.GLPixelAttributes matching GL, componentCount and pack.

  Parameters:

  gl - the corresponding current GL context object

  componentCount - RGBA component count, i.e. 1 (luminance, alpha or red), 3 (RGB) or 4 (RGBA)

  pack - true for read mode GPU -> CPU, e.g. glReadPixels. false for write mode CPU -> GPU, e.g. glTexImage2D.

• getHostPixelComp

  PixelFormat.Composition getHostPixelComp(GLProfile glp, int componentCount)

  Returns the host PixelFormat.Composition matching GL and componentCount if required by implementation, otherwise null.

  Parameters:

  glp - the corresponding current GL context object

  componentCount - RGBA component count, i.e. 1 (luminance, alpha or red), 3 (RGB) or 4 (RGBA)

• allocate

  GLPixelBuffer allocate(GL gl, PixelFormat.Composition hostPixComp, GLPixelBuffer.GLPixelAttributes pixelAttributes, boolean pack, int width, int height, int depth, int minByteSize)

  Allocates a new GLPixelBuffer object.

  The minimum required remaining byte size equals to minByteSize, if > 0, otherwise utilize GLBuffers.sizeof(GL, int[], int, int, int, int, int, boolean) to calculate it.

  Parameters:

  gl - the corresponding current GL context object

  hostPixComp - host pixel format, i.e. of the source or sink depending on pack, e.g. fetched via getHostPixelComp(GLProfile, int). If null, pixelAttributes instance maybe used or an exception is thrown, depending on implementation semantics.

  pixelAttributes - the desired GLPixelBuffer.GLPixelAttributes, e.g. fetched via getAttributes(GL, int, boolean)

  pack - true for read mode GPU -> CPU, e.g. glReadPixels. false for write mode CPU -> GPU, e.g. glTexImage2D.

  width - in pixels

  height - in pixels

  depth - in pixels

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