Method Detail

createWindowSurface

public void createWindowSurface(java.lang.Object surface)

Creates a window surface.

Specified by:

createWindowSurface in interface IEglSurfaceBase

Parameters:

surface - May be a Surface or SurfaceTexture.

createOffscreenSurface

public void createOffscreenSurface(int width,
                                   int height)

Creates an off-screen surface.

Specified by:

createOffscreenSurface in interface IEglSurfaceBase

getWidth

public int getWidth()

Returns the surface's width, in pixels.

If this is called on a window surface, and the underlying surface is in the process of changing size, we may not see the new size right away (e.g. in the "surfaceChanged" callback). The size should match after the next buffer swap.

Specified by:

getWidth in interface IEglSurfaceBase

getHeight

public int getHeight()

Returns the surface's height, in pixels.

Specified by:

getHeight in interface IEglSurfaceBase

releaseEglSurface

public void releaseEglSurface()

Release the EGL surface.

Specified by:

releaseEglSurface in interface IEglSurfaceBase

makeCurrent

public void makeCurrent()

Makes our EGL context and surface current.

Specified by:

makeCurrent in interface IEglSurfaceBase

isCurrent

public boolean isCurrent()

Specified by:

isCurrent in interface IEglSurfaceBase

makeCurrentReadFrom

public void makeCurrentReadFrom(java.lang.Object readSurface)

Specified by:

makeCurrentReadFrom in interface IEglSurfaceBase

swapBuffers

public boolean swapBuffers()

Calls eglSwapBuffers. Use this to "publish" the current frame.

Specified by:

swapBuffers in interface IEglSurfaceBase

Returns:

false on failure

setPresentationTime

public void setPresentationTime(long nsecs)

Sends the presentation time stamp to EGL.

Specified by:

setPresentationTime in interface IEglSurfaceBase

Parameters:

nsecs - Timestamp, in nanoseconds.

getEGLSurface

public javax.microedition.khronos.egl.EGLSurface getEGLSurface()
