Constructor Detail

GLPixelBuffer.DefaultGLPixelBufferProvider

public GLPixelBuffer.DefaultGLPixelBufferProvider(boolean allowRowStride)

Parameters:

allowRowStride - If true, allow row-stride, otherwise not. See getAllowRowStride() and GLPixelBuffer.requiresNewBuffer(GL, int, int, int).

Method Detail

getAllowRowStride

public boolean getAllowRowStride()

Description copied from interface: GLPixelBuffer.GLPixelBufferProvider

Allow GL2ES3.GL_PACK_ROW_LENGTH, or GL2ES2.GL_UNPACK_ROW_LENGTH.

Specified by:

getAllowRowStride in interface GLPixelBuffer.GLPixelBufferProvider

getAttributes

public GLPixelBuffer.GLPixelAttributes getAttributes(GL gl,
                                            int componentCount)

Description copied from interface: GLPixelBuffer.GLPixelBufferProvider

Called first to determine GLPixelBuffer.GLPixelAttributes.

Specified by:

getAttributes in interface GLPixelBuffer.GLPixelBufferProvider

allocate

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

Allocates a new GLPixelBuffer object.

Being called to gather the initial GLPixelBuffer, or a new replacement GLPixelBuffer if GLPixelBuffer.requiresNewBuffer(GL, int, int, int).

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.

Returns an NIO ByteBuffer.

Specified by:

allocate in interface GLPixelBuffer.GLPixelBufferProvider

Parameters:

gl - the corresponding current GL context object

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

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