SolutionThe LabVIEW Development Environment, by itself, does not have any built-in VIs for image manipulation that ship with the Base, Full, or Professional versions. Here are some approaches to manipulate your image: • The Zoom Factorproperty node of the 2D Picture control can be used to resize the image.
For example, a zoom factor of.5 will cause the image to be displayed at half of its native resolution. An image can also be placed in a custom image container, fit to the size of the image, using the Draw Area Size property node of the 2D Picture control. • To Resize an Image to Fit in a Picture Control. There is a Picture Control invoke node method called Get Image that returns the image data from the picture. You can use this after adjusting the zoom factor to get the resized image data, which can then be written to a file using the Write JPG File, Write PNG File, or Write BMP File VIs. However, this method may significantly distort the image.
The recommended method to resize image data is using the functions provided by the LabVIEW Vision Development Module for this purpose. For more information about the LabVIEW Vision Development Module, follow the link in the section below. • Manual Resize or Resampling as an Array (Advanced). You can also write your own algorithm to resize an image, but this can be a difficult task. In the Full and Professional versions of LabVIEW, you can import a picture and convert it to a Pixmap.
A Pixmap is a 2D array of numeric values that correspond to the color values of the individual pixels of the image. This conversion is done by importing an image into LabVIEW using the Read JPG File, Read PNG File, or Read BMP File VIs to read the appropriate file format. Once the image has been read into LabVIEW, you can use the Unflatten Pixmap VI to convert the picture information to a Pixmap.
These VIs, which are only available in the Full and Professional Versions of LabVIEW, are located on the Functions»Graphics and Sound»Graphics Formats palette. Once you have the image as a Pixmap, you can treat it as an array and do array manipulation to alter the image. At this point, you must write your own algorithm to manipulate the Pixmap to resize the image. Keep in mind that resizing an image cannot add new information when making an image larger, and will inevitably lose some information when making an image smaller, so careful consideration is needed to design an algorithm which preserves the most useful information for your application. For example, averaging neighboring pixel colors may tend to blur hard edges, making edge detection more difficult. Resampling images is still an active area of study with significant tradeoffs between efficiency and accuracy. For predicable results, the provides tools to resize or resample images.
You can then use the Flatten Pixmap VI to flatten the Pixmap back into the image data, and then save it to file with the Write JPG File, Write PNG File, or Write BMP File VIs. • Using the Zoom to fit feature.
Each DFLW character has unique combinations of strengths and weaknesses. DFLW was a major departure from previous versions in the Delta Force series by including realistic weapon recoil and 5 different player-selectable characters. Players can also select various combinations of characters and weapons, a unique freedom newer FPS games do not offer. For example, a player can select the medic character and use a sniper rifle or a machine gun. Delta force 4 game. Some of these unique character traits are running speed, reloading time, and weapon accuracy.

NI Vision Development Module Readme NI Vision Development Module 2011 SP1 Readme December 2011 This file contains important information about National Instruments Vision Development Module and is organized into the following sections: Refer to the Web site at ni.com/vision for the latest information about the NI Vision Development Module. Installing this program may remove previous versions of the NI Vision Development Module that are currently installed. The NI Vision Development Module 2011 supports LabVIEW 8.6, 2009, 2010, and 2011, Visual Studio 2005 and 2008, and LabWindows™/CVI™ 8.1 or later. The installer specifically allows side-by-side installations of NI Vision for each of the supported versions of LabVIEW, enabling you to use the NI Vision Development Module with multiple versions of LabVIEW. National Instruments recommends that you install LabVIEW, LabVIEW Real-Time, or any other supported development environment, before installing the NI Vision Development Module. Note: The NI Vision Development Module overwrites existing NI Vision examples and NI Vision VIs. Move modified examples or VIs that you want to save to another directory before installing the NI Vision Development Module.
