There is a shortcut to copy the content of the visualization area to the clipboard. Press CTRL+C to copy the whole visualization area with the same resolution as it is currently displayed. The result is the same as if you took a screenshot of the visualization area. The combination CTRL+C works the same both in 2D view and 3D rendering. Additionally, you can use CTRL+X. This has different effects in 2D and 3D visualization.

2D View

In 2D View using CTRL+X, an image of only the current domain is copied to the clipboard. The image has a 1:1 resolution of the structure, meaning that 1 voxel will be represented by 1 pixel in this image.

3D View

In 3D view, CTRL+X copies the whole visualization area with transparent background to the clipboard.
