Class EXTEGLImageStorage
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.
