Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "In OpenCV, a webcam can be accessed with a call to cv2.VideoCapture."

A block of code is set as follows:

def main():
    capture = cv2.VideoCapture(0)
    if not(capture.isOpened()):
        capture.open()
    capture.set(cv2.cv.CV_CAP_PROP_FRAME_WIDTH, 640)
    capture.set(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT, 480)

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "The Take Snapshot button is placed below the radio buttons."
