Structure SVG Overlay

All of the Allen Institute's annotated reference atlases have SVG files that contain structural boundaries. This example shows how you can access the SVG and SectionImage download contollers to download both the SVG and raw image data for a section.

The output of the controllers overlap directly. This page shows how to do this via JavaScript, but it's easy to do this manually in SVG viewers like Adobe Illustrator and Inkscape.

These images and SVGs tend to be very large, so both controllers have a 'downsample' parameter. Larger downsample values make the resulting SVGs and images smaller. A downsample value of 3 or 4 is good for high level inspection.

This page is interactive. Hover your mouse over the SVG image to see a tooltip showing the full name of the structure under the mouse cursor. You can choose a different section and downsample level on the URL like this.
