OmniTek OmniTek XR manual Generator Window, File Menu

7 Generator Window

With the Motion/Capture option, the product has a Generator window, providing access to those functions required for saving and loading data. The contents and operation of this window is described here.

File Menu

This lets you load and save configurations, where a configuration is a set of images and sequences. Note that you cannot use these choices to load individual images, as this is done from the Source menu.

This menu also lets you specify your Preferences for file loading.

Every time an image is loaded, its size is compared with the current video format. If it exactly matches, the image is loaded. If not, then the ‘Default pattern fit type’ is considered. This lets you specify a default action to take when loading images. One default action is to always pop up a dialogue box asking for a resize choice. The other options specify a default resize choice that the application will follow.

‘Load patterns once they are imported’ lets you control actions within a Gen configuration. When a configuration is loaded, a series of files are loaded into the control window. If this box is ticked, the actual video data is also loaded into the OmniTek card video memory. This would be the normal option to choose. However if you frequently wish to change configurations, and only use an occasional image or sequence from each configuration, then it may be quicker to clear this box, in which case no images are loaded with the configuration. To then load just a single image or sequence, merely click on the thumbnail and it will immediately start to load.

‘Re-load patterns once they have been saved’ is included to better cater for multiple file formats. For example, if a frame of video is captured, it is held in the frame buffer in the native YUV format. If you then save the image to disk as a .BMP image, the data has to be converted to RGB. The YUV frame being displayed will no longer accurately represent the file that has been saved due to the conversion from YUV to RGB. Ticking this box always forces the image to be reloaded. In this example, the RGB file would be loaded, converted into YUV and displayed. Although the image is back in YUV format, there would normally be significant changes to the colour information with respect to the original YUV image that was captured.
