Viewer Settings

The buttons have the following functions:


1. Exit	The exit selector provides two functions (a) exiting the viewer and navigating to a different location in the SIMBA system and (b) selecting a different image viewer. In the latter case your selection should be used for future image viewings for that SIMBA session When changing viewers, the viewer is initialized with the same images(s) with which the current viewer was initialized; any modifications from the initial viewer state will be lost.
2. Layout	The viewer is capable of presenting four different images simultaneously if screen resources permit. Layout selects which of the four image view panels are to be visible. When the viewer is started with a single image only view panel 1 is visible. When the viewer is started with two images then view panels 1 and 2 are made visible.
3. Overlay	The overlay selects which image meta-data will be displayed on all visible view panel images. Also color of text and a black background may be selected.
4. AStyle	The AyStyle selects the presentation style of an annotation boundary with respect to color and line thickness.
5. Cart.	The Cart buttons toggles between Cartesian pixel indexing and table/array pixel indexing. By default the viewer uses table/array indexing in which 0,0 is at the top left corner of the image. In Cartesian indexing pixel 0,0 is at the bottom left corner of the image. Currently, in Cartesian mode, the interactive annotation tools still use table/array indexing in their image displays.
6. Dark.	The Dark button toggles between a light background presentation and a dark background presentation. The dark mode is preselected on the medical viewer and is not selected on the advanced viewer.
7. Fill.	The Fill button toggles the fill option. When selected the viewer magnifies the image to fill the available viewing space.Otherwise the image is displayed at size 512 x 512 pixel which may be manually modified. The fill option is preselected on the medical viewer and is not selected on the advanced viewer.
8. 1--2.	The 1--2 buttons toggles image linking between view panels 1 and 2. When linked scrolling in one view panel will also scroll in the other view panel; thus, maintaining synchronization. The current simple scheme is based just on the image index not on the "slice thickness" for medical images. Thus is it not to be confused with the actual distance linking used in most medical image viewers.
9. Pend	This is an indicator that displays how any images the viewer has requested from the server but has not yet received. This should only be a high number for rapid animations or when loading a large set of images. When this number becomes 0 the last requested image will be displayed

Image Settings

The buttons have the following functions:


1. Load	The load selector allows for the loading a new image or an image annotation to the viewer panel. Select the load option to load a new image (or to change directory when used with vsimba workstation mode). A pop-up menu will provide you with the image options and a related "Load" button for each image. Select the Annotations option to load a new image annotation. A pop-up menu will provide you with the annotation options for the currently viewed image and a related "Load" button for each annotation.
2. Focus	The focus point (small yellow square) is a point annotation set by the user. It positions the center of the image when zooming allowing for convenient magnification of a region of interest. The Focus selector allows the focus feature to be set and to be activated. The "Show/Hide" option toggles the visibility of the focus point (shown as a small yellow square when activated). When activated (and visible) the image is repositioned during a zoom operation to maintain the focus point at the center of the image. To set the zoom location, click the left mouse button at the desired image location and then select the Focus "Set" option.
3. Bk.Mrk.	The Bndry button toggles the visibility of a bookmark location. The location is identified with a small red square annotation.
4. Bndry	The Bndry buttons toggles the visibility of any boundary annotations.
5. Interp.	The Interp. button toggles between bi-linear pixel interpolation and no (zero-order) pixel interpolation. The default is bi-linear interpolation. Zero-order interpolation is used when the user is interested in seeing the actual pixel regions.
6. Tools	The Tools button toggles the visibility of the tools panel located on the right side of the view panel.
