Constructor Detail

GlTextureFrameBuffer

public GlTextureFrameBuffer(int pixelFormat)

Generate texture and framebuffer resources. An EGLContext must be bound on the current thread when calling this function. The framebuffer is not complete until setSize() is called.

Method Detail

setSize

public void setSize(int width,
                    int height)

(Re)allocate texture. Will do nothing if the requested size equals the current size. An EGLContext must be bound on the current thread when calling this function. Must be called at least once before using the framebuffer. May be called multiple times to change size.

getWidth

public int getWidth()

getHeight

public int getHeight()

getFrameBufferId

public int getFrameBufferId()

getTextureId

public int getTextureId()

release

public void release()

Release texture and framebuffer. An EGLContext must be bound on the current thread when calling this function. This object should not be used after this call.
