The Image Viewer is the main interface of GC Image. The Image Viewer has (from top to bottom):
- title bar, which just displays the name of the current image;
- menu bar, which provides menu access to all operations, tools, settings, and help resources;
- tool bars, with buttons for commonly used operations, tools, and cursor modes;
- Viewport, which displays the region-of-interest of the current image with axes; and
- status bar, which displays the position and value of the image pixel at the cursor location.
Step 1: With the cursor over a border or corner of the Image Viewer window, click-and-drag the border or corner to the desired size. (The Maximize button on the title bar makes the Image Viewer fill the screen and the Restore down button will restore the previous size after maximization.)
Step 1: Select View mode from the Image Viewer
cursor-mode palette.
Step 2: With the cursor in the Viewport, click-and-drag with the left mouse-button to shift the image as desired. (Also, after clicking in the image, use the arrow, page-up, and page-down keys.)
Step 1: Select a value from the pull-down menu of scale factors
or type a value in the textbox in the Scale Viewport tool on the
Image Viewer tool bar.
Step 1: Select Set Viewport from the View menu of the
Image Viewer.
GC Image launches a pop-up dialog box for the desired dimensions and position.
Step 2: Specify the desired values, then click OK.
Step 1: Select View mode from the Image Viewer cursor-mode palette.
Step 2: With the cursor in the Viewport, click-and-drag with the right-mouse button to delimit the desired region of interest.
Step 1: Click the Reset Display button on the Image Viewer tool bar.
GC Image maintains a view list with successive size and scale settings and provides backward and forward navigation buttons similar to the backward and forward buttons on a web browser. To go back to the previous size and scale, click the Previous button on the toolbar. To go forward to the next size and scale, click the Next button on the toolbar.
The Navigator provides a "thumbnail" view of the entire
image (typically at reduced resolution).
The Navigator also provides an interface to visualize and relocate
the region-of-interest (ROI) that is displayed in the Viewport
of the Image Viewer.
The Navigator can be set to maintain aspect ratio or to fit the
image to the window.
Navigator can be launched by the tool bar button or from the
View menu of the Image Viewer.
Step 1: With the cursor in the ROI box of the Navigator, click-and-drag the ROI to the position desired. More precise positioning can be specified via the Set Position button on the Navigator tool bar.
Step 1: With the cursor positioned on a corner of the ROI box of the Navigator, click-and-drag the corner of the ROI to the size desired.
Step 1: Select Configure Settings from the Configure
menu of the Image Viewer.
GC Image launches a pop-up with various configuration dialog panes.
Step 2: Select the Axes configuration pane.
Step 3: Select the desired units for the axes (e.g.., time or pixels). Click the OK button.
