Event Type
Picture File

The Picture File event type lets you select and display picture files.  You can select a single file or have the event pick a file from a stimulus list.  You can also have the visual stimulus displayed at different locations, in random or sequential order.  The supported file formats are:

The Event Editor can be resized.  This can come in handy if you want to see a larger thumbnail view of your stimulus.

 

There are two main views in the Picture File event type: Settings and File Info.  The File Info view provides information about the selected file.  If the event uses a stimulus list instead of a single file, no information is displayed.

In the Settings view:

Picture Settings

When you click on the Settings button, another dialog appears that provides a range of options for controlling the position and size of the picture as well as other display options:
 

 

The Position tab lets you determine the picture’s position.  You can specify either a fixed location by providing a specific pixel position or a variable location by using the Trial Variables feature.  A variable location can be sequential or random.

You can use the Size tab to change the picture file’s dimensions.  SuperLab uses an anti-aliasing technique to minimize distortion and provide the best possible picture quality when a picture file is resized.

The Presentation Options tab provides additional options for doing things like showing multiple pictures on the screen, either in sequence or simultaneously.
