The RenderTarget node has the same functionality as the Canvas node but is used for off-screen image rendering.

The RenderTarget node is often used to obtain an intermediate result in a series of image geometry transformations.

When the RenderTarget node is added in the Node Graph, a corresponding widget becomes accessible that allows editing Displays and Patches connected to the RenderTarget node. The widget can be added to the workspace by selecting Window > <RenderTarget Name> from the main Screenberry Panel menu. For more information on editing displays and patches see the  Display Editor and Patch Editor sections of this user guide.

To preview the RenderTarget resulting image, the node can be connected to the VideoPreview node, which has its own widget that can be added to the workspace.

The Settings panel of the RenderTarget node offers the following control and information parameters:

Image SizeEnables/disables rendering of the off-screen image.
Number of ChannelsSpecifies the number of channels for the rendered image.
Bits per ChannelSpecifies the color depth for the rendered image.
StereoscopicEnables/disables stereoscopic image rendering.
Multisample Anti-Aliasing (MSAA)Improves the appearance of rendered patch edges (makes them smoother). This anti-aliasing option only affects patches that are rendered directly to the Canvas or Displays.
Color BufferEnables use of a color buffer.
Depth BufferEnables use of a depth buffer.
DisplaysDisplays information about the number of Display nodes connected to the RenderTarget node.
PatchesDisplays information about the number of Patch nodes connected to the RenderTarget node.
Background ImageProvides information about the image source connected to the Canvas node as a background image.
Image Wrap ModeAllows selecting a texture wrapping mode. When Clamp to Edge mode is selected, the texture is applied once, then the colors of edge pixels are smeared. In Clamp to Border mode, an arbitrary border color (black) is applied.
Image FormatDerives the image format from an external image. The pin for this parameter is hidden by default and should be enabled for connecting an image.
Use External Image FormatSpecifies that the size and pixel format of an external image connected to the Image Format parameter will be used for rendering.
ImageOutputs the rendered image.
