Class EXTEGLImageStorage


  • public class EXTEGLImageStorage
    extends java.lang.Object
    Native bindings to the EXT_EGL_image_storage extension.

    The OpenGL ES extension OES_EGL_image provides a mechanism for creating GL textures sharing storage with EGLImage objects (in other words, creating GL texture EGLImage targets). The extension was written against the OpenGL ES 2.0 specification, which does not have the concept of immutable textures. As a result, it specifies that respecification of a texture by calling TexImage* on a texture that is an EGLImage target causes it to be implicitly orphaned. In most cases, this is not the desired behavior, but rather a result of an application error.

    This extension provides a mechanism for creating texture objects that are both EGLImage targets and immutable. Since immutable textures cannot be respecified, they also cannot accidentally be orphaned, and attempts to do so generate errors instead of resulting in well-defined, but often undesirable and surprising behavior. It provides a strong guarantee that texture data that is intended to be shared will remain shared.

    Requires GLES 3.0. Requires EGL 1.4 and either the EGL_KHR_image or EGL_KHR_image_base extensions.
