View your multi-channel data as a montage with one image per channel plus a merged, color channel (useful to create figures for communication)
Institution: Institut Pasteur
This viewer plugin will split all N channels of the active sequence into a montage of N+1 images, with one image for each channel, plus an additionnal color (merge) rendering.
Accessing the viewer
This viewer can be activated via the “viewing mode” drop-down list on any viewer, as shown below. If “channel montage” is not in this list, make sure it is installed (use the search bar, or the plugin browser)
Using the viewer
The montage is currently assembled with the following rules:
- Images are assembled automatically to fit best the shape of the window. This means that by resizing the window, you may switch a square-like montage (see screenshot below) to a linear horizontal (or vertical) montage, whichever you (or your favorite journal) fancy.
- Images have a default maximum width or height of 250 pixels (whichever is bigger), separated by a 5-pixel margin. The size of these images can be adjusted using the dedicated option right above the views. The margin is currently fixed, but if you need more flexibility, feel free to send feedback via the forum!
And here is a list of features (and caveats) that you might otherwise figure out by yourself, it just saves you time:
- Contrast: Images respect the colormap choices from the inspector. Therefore, you may continue adjusting the brightness/contrast using the blue and red bars to optimize the rendering
- Grayscale: A grayscale checkbox lets you switch all single-channel views to grayscale, while only the final, merged image will remain colorized. This is particularly convenient when viewing low-contrast data, especially with a projector during a presentation, where you try to have people see something.
- ROI: the regions of interest (ROI) are obviously the same in all views, and you can keep editing them in this viewing mode.
- Screenshot issue: the two screenshot buttons on top of the viewer aren’t currently supported (they will be in the future). In order to get export nice renderings, you have to fall back to traditional screenshot programs (make sure the montage is big enough, those screenshots will have a low dpi resolution)
