About argument specification of eglCreateImageKHR ()

Hi aki,

You just need to be sure that the platform you are using supports the extension EGL_KHR_image_pixmap. The definition of EGLClientBuffer should already be available to you. The EGLClientBuffer is just an opaque handle to the resource and you don't need to know the internal structure.

You just need to create a native_pixmap and the EGLSurface to be used in eglCreateImageKHR:

egl_native_pixmap_t pixmap;

//Fill pixmap with the proper data

EGLSurface eglPixmap = eglCreatePixmapSurface(dpy, config, pixmap,  eglPixmap_attrib_list );

//Create the eglImage from the eglPixmap

EGLImage eglImage = eglCreateImageKHR (dpy, ctx, EGL_NATIVE_PIXMAP_KHR, (EGLClientBuffer) eglPixmap, eglImage_attrib_list);

Regards,

Daniele

Thanks for the reply Daniele.

I was able to solve the problem.
Thank you.

Aki  what did  you pass in eglPixmap_attrib_list , I have a buffer and I want to create a pixmap from that buffer and then create egl image.

where should I use that buffer while creating pixmap.

Thank you
