When you open the pylon Viewer for the first time, the following panes will be displayed:
The Devices pane displays a device tree in which all cameras that are connected to your computer are listed grouped by interface type. The interfaces shown vary depending on which options you have chosen during the installation of the pylon Camera Software Suite. As an example, a Basler boost CXP-12 camera, Basler ace 2 GigE camera, a Basler pulse USB camera, a Basler ace USB camera, and a camera emulation device are shown in the screenshot above. Using the Show Cameras Only option, you can display only the cameras without the interface information.
In this pane, you can also select whether to auto-scan in regular intervals for recently connected devices. Alternatively, you can click the Refresh button to refresh the device tree manually.
The Features pane displays the features of the camera that is selected in the Devices pane. By default, it contains two tabs:
- Features – All: This pane lists all features that are available on the camera currently selected. Here, you also have the option to group features that you need frequently or for a specific task. For instructions how to do this, see To group features below.
- Features – Basic: This tab contains a reduced set of features that allows you to quickly set up a camera.
To group features:
- Click the Edit Feature Tabs button.
- In the Edit Feature Tabs dialog, enter a name for the new tab.
- Drag the desired features from the Features pane into the Edit Feature Tabs dialog.
- When you have finished adding features, click OK.
The new feature tab will be displayed in the pylon Viewer. You can dock it like the other tabs or leave it floating. The new tab will also be added to the Window menu.
You can use this custom tab for all camera models, i.e., you can create a tab for an ace 2 GigE camera and use it when you're working with an ace USB camera. As the feature sets of these camera models differ, features available on the ace 2 GigE won't be displayed when you're using the ace USB model. If you want to see these unavailable features, select the Show Unavailable Features check box.
Feature tabs created by you can be changed. You can add features, delete features, or change the name of the tab. The Features – All and Features – Basic tabs can't be edited.
To edit a feature tab:
- Click the Edit Feature Tabs button.
- In the Edit Feature Tabs dialog, select the tab that you want to edit.
- Make the desired changes.
- Click OK.
Another feature of the Features – All tab is the Common Tasks drop-down list. This is designed to help you quickly complete a variety of common tasks, i.e., changing the resolution or optimizing image quality. By selecting one of the tasks, the relevant features will be highlighted in the feature tree.
On this tab, you can also select whether to automatically poll the camera in regular intervals. Alternatively, you can click the Refresh button to refresh the features list manually.
Image Display Area#
Images and videos taken by the camera are displayed here. There is an image window tab for each camera that is currently open. At the bottom is a status bar that provides information about the image you're capturing or the video you're recording. When positioning your camera, you can display a crosshair and grid as visual aids. Images can be displayed in full-screen mode by clicking the button in the toolbar. To move the full-screen image to a second screen, right-click in the image and then click Screen #2. The image will then move to your second screen.
Feature Documentation Pane#
The Feature Documentation pane displays information about the feature currently selected in the Features pane. The feature descriptions are available in a variety of languages. Pick your language in the Language drop-down list.
Feature Properties Pane#
The Feature Properties pane displays information about the parameter currently selected in the Features pane. Initially, it appears minimized and docked on the right-hand side of the pylon Viewer.
Message Log Pane#
The Message Log pane displays information about actions carried out with the pylon Viewer, e.g., opening and closing a camera or starting a recording. There are different message levels: Information, Warning, and Critical. Initially, it appears minimized and docked on the right-hand side of the pylon Viewer.
Via the Window menu, you can select more panes to display. By default, some of them will be docked on the right-hand side of the pylon Viewer, others will be floating.
All panes in the main window have buttons for closing the pane and for undocking it from the pylon Viewer window. If a pane is undocked, you can move it around freely on your desktop. If you want to dock it again, follow these steps:
- Start dragging a pane.
A positioning aid appears.
- With the mouse cursor, point to the location where you want to drop the pane.
The desired window area will be highlighted in blue.
- Drop the pane.
The following animation demonstrates this.
This way you can fully customize the pylon Viewer window and rearrange panes as desired.
