GC Image provides several tools for visualizing image data.
- Multi-Projections graphs one-dimensional slices and projections of an image.
- Text View provides a tabular view of the image data values.
- 3D View tool provides a three-dimensional perspective view of the image data values.
- Visualize Data provides pixel statistics and plots statistical relationships for an image or sub-image.
All of these tools are accessible from the View menu of the Image Viewer.
Step 1: In the Multi-Projections control pane, select integrated projection mode.
Step 2: In the Multi-Projections image pane, click on a
pixel of the desired row and column. GC Image graphs the row slice at
the bottom of Multi-Projections and the column slice at the right
of Multi-Projections.
Step 1: In the Multi-Projections control pane, select integrated projection mode.
Step 2: In the Multi-Projections image pane, click-and-drag
from one side of the desired row and column range to the other side.
GC Image graphs the row projection at the bottom of Multi-Projections
and the column projection at the right of Multi-Projections.
Step 1: In the Multi-Projections control pane, select multiple slices (Multi) projection mode.
Step 2: In the Multi-Projections image pane, click-and-drag from one side of the desired row and column range to the other side.
Step 3: In the Multi-Projections image pane, set the number
of horizontal and vertical slices with the sliders or enter values in the
text boxes and hit the RETURN or ENTER.
GC Image graphs the row slices at the bottom of Multi-Projections
and the column slices at the right of Multi-Projections.
Step 1: At the bottom of the Multi-Projections control pane, click either the horizontal or vertical save buttons. GC Image launches a file-system browser.
Step 2: Specify the file location and name for the CSV file.
Step 1: If desired, select a rectangular sub-region of the image, using the graphics tool for drawing rectangles, to see the values in the rectangle. Or, select a blob to see the values in the bounding box of the blob.
Step 2: Select Text View from the View menu of the
Image Viewer or click the Text View button on the Image
Viewer tool bar. GC Image launches a pop-up tool with the text table
of values.
Step 1: Click the Save text view button on the Text View popup. GC Image launches a file-system browser to specify the folder and CSV filename.
Step 2: Specify the file location and name, then click Save.
Step 1: If desired, select a rectangular sub-region of the image, using the graphic tool for drawing rectangles, to see the values in the rectangle.
Step 2: Select 3D View from the View menu of the
Image Viewer or click the 3D View button on the Image
Viewer tool bar. GC Image launches a pop-up tool with the three-dimensional
perspective view.
Step 3: Reposition the image using the latitude, longitude, and distance sliders on the 3D View control panel or with mouse actions:
- Translate by click-and-drag with the right mouse-button.
- Rotate by click-and-drag with the left mouse-button.
- Zoom (or scale) by click-and-drag with the middle mouse-button.
Currently, translation is available only through the mouse action.
Step 1: On the 3D View control panel, select the surface as wireframe or continuous.
Step 2: Select the color as monochromatic or colorized. For a monochromatic display, select the color. For a colorized display, set the image color map.
Step 3: Select the initial resolution. Resolutions larger than 1.0 (the default) for large images may require more memory than is available and cause the program to fail.
Step 4: Click the Apply Above Settings button.
Step 1: If desired, select a rectangular sub-region of the image using the graphic tool for drawing rectangles.
Step 2: Select Visualize Data from the View menu
of the Image Viewer.
GC Image launches Visualize Data.
Step 3: Select the statistics for the X and Y axes.
Step 4: If desired, click the Histogram button.
GC Image launches Histogram tool.
