Image View Dialog

This dialog allows you to display image planes on the model data. Any of the three native orthogonal planes can be displayed, alone or in combination. Transparency can be set to allow the model to be seen through the image; a projection through multiple slices can also be displayed.

If data have been loaded into the program as 16-bit integers instead of bytes, they are first converted to bytes using the scaling determined by the the Low and High sliders in the Information window. For best results, be sure that the Low and High sliders are set so that images have a good contrast with a fairly wide range between the Black and White sliders. Using the autocontrast function generally leaves the sliders in positions that will allow good scaling for display. Changing the Low and High sliders will change the contrast of this image display.

The first three check boxes (X, Y, and Z in Image plane to show) turn on the display of the indicated image planes. The hot key Z or Shift+Z will turn the Z image on or off, while Shift+X and Shift+Y will toggle the X and Y image planes.

The X, Y, and Z checkboxes inside Clip model near plane in enable a display of a portion of the model just on or near the displayed plane. It sets up clipping planes on each side of the selected image slice to restrict what portion of the model appears. The clip plane on the back side is right up against the image plane and the plane on the front can be offset from the image plane. The Gap: spin box entry sets the gap between the clipping planes, which corresponds to how many extra slices of model appear. In addition, if you step the spin box below 0, it is equivalent to setting an infinite gap; i.e., the entire model on one side of the plane will appear. The spin box will show "uni" for unidirectional. Note these points:
