Display features during design-time

You can zoom the flowchart using the sliding zoom bar, which fades in more clearly as you hover over the top-right of the flowchart. To zoom the selected step's displayed image, use the mouse wheel or click the Zoom In () or Zoom Out () toolbar buttons in the Project toolbar.

The display status bar, located below the selected step's displayed image, shows the X- and Y-coordinates (and Z-coordinates in the case of depth maps), as well as the gray intensity or color value, at the position of your mouse cursor as it passes over the image (the zoom factor is also shown). The coordinates are in calibrated world units if the step's image is associated with a calibration; to show them in pixel units, right-click on the image and uncheck the Calibrated Coordinates context menu item.

You can modify if annotations are hidden, or how they are displayed, using the Annotations control panel. This is opened by clicking on the Annotations toolbar button in the Project toolbar. The Annotations control panel provides a list of all the annotations in the project, grouped according to the steps to which they belong. You can choose which annotations appear in the list using the Filter button, specify the annotations to display on the image using the Visibility button, modify the visibility of callout annotations using the Callout visibility button, and select the colors in which to display annotations from the available Color options.

You can choose an image to display from the various images associated with a step, or choose an image for a step without its own input image. You can also view multiple images for a selected step in the display view. For more information, see the Displaying a step's images section in the Display view reference chapter.

There are 3 graphs that convey pixel data about the selected step's displayed image: the Line Profile graph, the Histogram graph, and the Edge Values graph.

In the Project toolbar, you can access these graphs by clicking on their respective toolbar buttons . The graphs are for design-time and do not directly impact the project. They are intended to provide useful information for setting up the project. For example, you can use the Line Profile graph to draw a line across a dot that makes up a dot-matrix character. This lets you determine where the pixel intensity shifts, from bright to dark and from dark to bright. You can use the distance between these major intensity shifts to establish the dot diameter to use for performing character recognition with the SureDotOCR step.

For images with more than 8 bits per band, you can select a View mode to produce an 8-bit displayable image. For more information on the available view modes and how they display images, see the Displaying images with more than 8-bits section in the Display view reference chapter.
