public static interface GLPixelBuffer.GLPixelBufferProvider

Allows user to interface with another toolkit to define GLPixelBuffer.GLPixelAttributes and memory buffer to produce TextureData.

Method Summary

Methods

Modifier and Type	Method and Description
GLPixelBuffer	allocate(GL gl, GLPixelBuffer.GLPixelAttributes pixelAttributes, int width, int height, int depth, boolean pack, int minByteSize) Allocates a new GLPixelBuffer object.
GLPixelBuffer.GLPixelAttributes	getAttributes(GL gl, int componentCount) Called first to determine GLPixelBuffer.GLPixelAttributes.

Method Detail

getAttributes

GLPixelBuffer.GLPixelAttributes getAttributes(GL gl,
                                            int componentCount)

Called first to determine GLPixelBuffer.GLPixelAttributes.

allocate

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.

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.
