Using CFEO

Additional tools

Once you have selected images to view in the display pane, you can then zoom in on them to make it easier to see details, or pan them around to see different parts of the image or to allow easier comparison of passages in more than one image if you have chosen to view two or more images simultaneously. There are a number of tools available within the display frame to allow you to work with and navigate through the images effectively, and these are detailed below:

The above screenshot shows what the display pane looks like with two images shown for comparison – in this case, a zoomed excerpt from p. 1 in the French and Austrian First Editions.

  1. Title bar: the blue strip across the top of each displayed image contains the title of the work, the source, the page reference, the bar range, and copyright information (which also indicates the institution that owns the given score), allowing you to see at a glance which image(s) are being shown.
  2. Clicking 'Previous' will change the display to show the preceding image (i.e. preceding page) in the edition. This allows you to turn a 'page' backwards at a time as though you were working with the physical score.
  3. Similarly, clicking 'Next' reveals the following page in the edition. Note that even if you have chosen to view images only in a particular movement or work component, using the 'Previous' and 'Next' controls will allow you to page through the entire score.
  4. The 'Close frame' link appears only if more than one image is displayed. It allows you to close off the second and third images to create more space to display a single image by itself.
  5. The browse tab can be useful, especially if you're working with more than one image, since you can use it to hide the browse pane and create additional screen space to optimise the display of the images.
  6. Beneath each of the displayed images is a small control panel which allows you to zoom and pan the images themselves. The large 'plus' icon incrementally zooms into the image when clicked.
  7. Similarly, the 'minus' icon zooms out.
  8. The four arrow controls allow you to pan the image up, down or sideways.
  9. The miniature 'hand' icon allows you to bring up or turn off a separate navigation pane. When the latter is shown, the displayed area of the relevant image appears in a box within the navigation pane. Clicking on the 'hand' icon allows you to hide the pane if you find it distracting, or if it is obscuring an important part or feature of the image.
  10. The last button on the toolbar allows you to reset the zoom and pan settings back to the default values.
  11. The upward-pointing triangle above the other controls can be moved laterally, allowing you to control the zoom factor more smoothly and with greater precision. Clicking the triangle and dragging it to the right increases the zoom level; dragging it to the left decreases the zoom (i.e. zooms out).

In addition to the zoom and pan controls on the images themselves, you can click and drag the image with your mouse to pan it around, which will give you a finer degree of control. Clicking the image itself will progressively zoom in on the point at which you are clicking.
