<brief_description>
Texture which displays the content of an external buffer.
</brief_description>
<description>
Displays the content of an external buffer provided by the platform.
Requires the [url=https://registry.khronos.org/OpenGL/extensions/OES/OES_EGL_image_external.txt]OES_EGL_image_external[/url] extension (OpenGL) or [url=https://registry.khronos.org/vulkan/specs/1.1-extensions/html/vkspec.html#VK_ANDROID_external_memory_android_hardware_buffer]VK_ANDROID_external_memory_android_hardware_buffer[/url] extension (Vulkan).
[b]Note:[/b] This is currently only supported in Android builds.

<methods>
<method name="get_external_texture_id" qualifiers="const">
<return type="int" />
<description>
Returns the external texture ID.
Depending on your use case, you may need to pass this to platform APIs, for example, when creating an [code]android.graphics.SurfaceTexture[/code] on Android.

<method name="set_external_buffer_id">
<return type="void" />

<description>
Sets the external buffer ID.
Depending on your use case, you may need to call this with data received from a platform API, for example, [code]SurfaceTexture.getHardwareBuffer()[/code] on Android.
