RedBrick AI’s Preview Tool allows users to see how their images, volumes, and annotations are displayed within RedBrick AI’s Annotation Tool without having to create a Project or integrate a third-party Storage Method.

As of v1.2.3., users can preview images and/or annotations from either their local machine or any Storage Method they have integrated into their RedBrick Organization.

​

Previewing a Local File

1. Open the Preview Tool, located in the lefthand sidebar of the Home Page;
2. Select a file source: Load from file system;
3. Within Preview Tool, select the image(s) you would like to display or simply drag and drop them into the corresponding left hand window;
4. (Optional) select the annotation file you would like to display or simply drag and drop it into the corresponding right hand window;
5. Click on View Data;
6. Use the Manage Files button (top right hand corner) and Replace buttons (in the dialog menu) to swap out new files as needed;

​

Previewing a File on your Storage Method

Once you have opened the Preview Tool and selected Load from Storage Method:

1. Select a file source: Load from Storage Method;
2. In the Select your external storage dropdown, choose a Storage Method;
3. In the List of items field, provide the partial or full paths for the images you wish to preview, separated by a comma or newline;
4. Click on View Data;
5. Use the Manage Files button (top right hand corner) and Replace buttons (in the dialog menu) to swap out new files as needed;

• Windowing Settings
• Thresholding Settings
• MPR Layout
• Command Bar (and commands such as “toggle Linear Pixel Interpolation”, “toggle permanent crosshairs”, etc.)
• Oblique Planes

• …and more!
