Detailed Description

Class representing EGL PBuffer surface.

Constructor & Destructor Documentation

EGLPBufferSurface() [1/2]

kanzi::EGLPBufferSurface::EGLPBufferSurface ( const EGLDisplay & eglDisplay, const EGLConfig & eglConfig, int width, int height )

explicit

Constructor.

Creates a PBuffer surface of the default color space, unsuitable for use as a texture.

Parameters

eglDisplay	EGL display connection.
eglConfig	EGL configuration to use.
width	Width of the PBuffer surface in pixels.
height	Height of the PBuffer surface in pixels.

Postcondition

isNoSurface() returns false for this object.

egl::getError() returns EGL_SUCCESS.

EGLPBufferSurface() [2/2]

kanzi::EGLPBufferSurface::EGLPBufferSurface ( const EGLDisplay & eglDisplay, const EGLConfig & eglConfig, const int * attributes )

explicit

Constructor.

Parameters

eglDisplay	EGL display connection.
eglConfig	EGL configuration to use.
attributes	Array of extra attributes.

Postcondition

isNoSurface() returns false for this object.

egl::getError() returns EGL_SUCCESS.

Member Function Documentation

getNoSurface()

static KZ_NO_DISCARD ::EGLSurface kanzi::EGLPBufferSurface::getNoSurface ( )

staticnoexcept

Gets a no surface EGL surface handle.

Returns

EGL surface handle with a value representing no surface.

destroy()

bool kanzi::EGLPBufferSurface::destroy

(

const EGLDisplay &

eglDisplay

)

Destroys EGL PBuffer surface.

Call this before destructing the object.

Parameters

eglDisplay

EGL display connection.

Postcondition

egl::getError() returns EGL_SUCCESS.

swapBuffers()

bool kanzi::EGLPBufferSurface::swapBuffers

(

const EGLDisplay &

eglDisplay

)

const

Posts rendering results.

Implicitly flushes the rendering pipeline and executes all received rendering commands before posting.

Parameters

eglDisplay

EGL display connection.

See also

swapInterval().

Returns

True on success, false on failure.

Postcondition

egl::getError() returns EGL_SUCCESS.

getNativeHandle()

KZ_NO_DISCARD::EGLSurface kanzi::EGLPBufferSurface::getNativeHandle ( ) const

noexcept

Gets EGL PBuffer surface handle.

Returns

EGL PBuffer surface handle.
