Class GLPixelBuffer

Method Details

• toString

  public StringBuilder toString(StringBuilder sb)

• toString

  public String toString()

  Overrides:

  toString in class Object

• getAllowRowStride

  public final boolean getAllowRowStride()

  Allow GL2ES3.GL_PACK_ROW_LENGTH, or GL2ES2.GL_UNPACK_ROW_LENGTH.

• isValid

  public boolean isValid()

  Is not disposed and has byteSize > 0.

• rewind

  public Buffer rewind()

  See Buffer.rewind().

• position

  public int position()

  Returns the byte position of the buffer.

• position

  public Buffer position(int bytePos)

  Sets the byte position of the buffer.

• capacity

  public int capacity()

  Returns the byte capacity of the buffer.

• limit

  public int limit()

  Returns the byte limit of the buffer.

• flip

  public Buffer flip()

  See Buffer.flip().

• clear

  public Buffer clear()

  See Buffer.clear().

• requiresNewBuffer

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

  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 GLBuffers.sizeof(..) is being used to calculate it. This value is referred to newByteSize.

  If allowRowStride = false, method returns true if the newByteSize > currentByteSize or the newWidth != currentWidth.

  If allowRowStride = true, see GLPixelBuffer.GLPixelBufferProvider.getAllowRowStride(), method returns true only if the newByteSize > currentByteSize. Assuming user utilizes the row-stride when dealing w/ the data, i.e. GL2ES3.GL_PACK_ROW_LENGTH.

  Parameters:

  gl - the corresponding current GL context object

  newWidth - new width in pixels

  newHeight - new height in pixels

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

• dispose

  public void dispose()

  Dispose resources. See isValid().
