<return type="ViewportTexture" />
<description>
Returns the viewport's texture.
[b]Note:[/b] Due to the way OpenGL works, the resulting [ViewportTexture] is flipped vertically. You can use [method Image.flip_y] on the result of [method Texture2D.get_image] to flip it back, for example:
[codeblocks]
[gdscript]
var img = get_viewport().get_texture().get_image()
img.flip_y()
[/gdscript]
[csharp]
Image img = GetViewport().GetTexture().GetImage();
img.FlipY();
[/csharp]
[/codeblocks]
[b]Note:[/b] When trying to store the current texture (e.g. in a file), it might be completely black or outdated if used too early, especially when used in e.g. [method Node._ready]. To make sure the texture you get is correct, you can await [signal RenderingServer.frame_post_draw] signal.
[codeblock]
func _ready():
await RenderingServer.frame_post_draw
$Viewport.get_texture().get_image().save_png("user://Screenshot.png")
[/codeblock]
