Capture FIle

Menu:   Acquire > Capture

Script:   grabFile

This tab of the Capture dialog box lets you acquire a single image or a sequence of images from the video device selected in ImageWarp and store them in files.
File

Displays the template name for files in which captured images will be stored. In the single file mode, i.e., when the Frames value is set to zero, it is the name of the file to be created. In the multiple file mode, this name will be used as a prefix to which an ordinal index will be added. To select a different file name, type another name or click the Browse button.

Note – The image file format in which images will be stored is defined by the file extension. See Image File Formats for more details.

Start

Displays the index that will be assigned to the first image file captured in the multiple file mode. Index is the ordinal number added to the File template. For instance, if the file "C:\myimage.jpg" is specified, and the Start value is set to 100, the images will be stored to files "C:\myimage00100.jpg", "C:\myimage00101.jpg", "C:\myimage00102.jpg", and so on. If the Frames value is set to zero, the Start box will be unavailable.

Frames

Displays the number of images to be captured and stored in files. Type or select another value if you want to change the number of files to be recorded. Select zero to capture an image into a single file.

Delay

Displays the delay (in milliseconds) between consecutive video frames to be captured and stored in files. Type or select the desired interval between frames. The actual frame rate of capture depends on the video device, video frame size, and chosen file format, and it can exceed the selected delay time. In this case, ImageWarp will ignore the Delay value and use the least possible time between frames.

Live Preview

Check this box to have ImageWarp display a minimized live video in the preview window of the dialog box. During the capture process, live preview is automatically synchronized with the ongoing frame rate.

Note – it is not recommended that the live preview on the capture dialog be enabled while the Video Window is displayed because it can disturb the video stream and lower the frame rate.

Apply

Click this button to start capturing and storing frames in files. The progress indicator on the status bar will display the capture progress.

Note – you can stop capturing by pressing the PAUSE/BREAK key at any time during the capture process.
