Exporting Images

Overview

Nexus provides several ways to export images from your visualizations. All image export options are available from the nexus menu → Export Image submenu.

Image from 2D Viewer

Export the current view of an Image Viewer panel as a single image file.

  1. Open the nexus menu → Export Image → Image from 2D Viewer.
  2. Choose the output format: PNG, JPEG, or TIFF.
  3. Configure overlay options (scale bar, annotations).
  4. Click Save and choose a location.

The exported image includes the same adjustments (colormap, brightness, contrast, gamma, crop) that are applied in the viewer.

Image from Chart

Export a chart panel (Time Series, XY, or Spectrogram) as an image.

  1. Open the nexus menu → Export Image → Image from Chart.
  2. Select a chart panel.
  3. Choose between light or dark theme for the exported image.
  4. Click Save.

Image Series (Collage)

Create a grid layout of multiple frames from an image series in a single image.

  1. Open the nexus menu → Export Image → Image Series (Collage).
  2. Select the image series signal.
  3. Choose the frame selection mode:
    • Equal distribution — evenly spaced frames across the time range
    • Every Nth frame — select every Nth frame
    • Notes-based — select frames at note timestamps
  4. Configure the grid layout and frame labels.
  5. Click Export.

The collage uses an auto-calculated grid layout that fits the selected frames.

Image Series (Individual)

Export every frame (or a selection of frames) from an image series as individual image files.

  1. Open the nexus menu → Export Image → Image Series (Individual).
  2. Select the image series and configure frame selection.
  3. Choose the output format and a destination folder.
  4. Click Export.

Each frame is saved as a separate file with a sequential filename.
