====== Show Buffers Preview (Image Viewer) ======

{{ :exrtrader2018:image_viewer.png?400|}}

VIPER, which was used by exrTrader to preview buffers, has been removed from LightWave 3D. This is why we added a custom viewer for rendered buffers.

===== Title Bar =====

The title bar of the window displays:

  * The name of the current buffer
  * The way it is saved
  * The pixel data type (when saved as an OpenEXR image)
  * The extent of the data window of the current buffer
  * The values of a picked pixel if the user has clicked on the image

===== Toolbar =====
==== Buffer ====

Selects a different buffer to view.

==== Channel ====

Selects a single channel, or all channels, to view.

==== P ====

Toggles the processing of the buffer. This uses the settings of the processing tab of the buffer.

==== N ====

Normalises the view. Basically this makes sure that the pixel values within the image are completely distributed in the visible range.

==== CS ====

Allows the selection of a different colour space. By default, the Display colour space is used.

==== Zoom ====

Changes the zoom factor of the image

==== Fit ====

Toggles automatic fitting of the image to the viewer. Even if the window is resized. The image will be made to fit proportionally, leaving blank space if required.
===== Navigation =====
