Glossary

History
The set of images that has been downloaded by a cam window. More details

Name
The name of a cam is used to uniquely identify it. This name appears in the Control Centre's cam list and also in the properties panel. The name is the means by which a cam window is associated with its entry in the cam list. It is also used to determine the folder that the history is stored in.

Refresh
A cam window refreshes itself by downloading the content of its URL. This is usually a JPEG image which contains the actual cam picture.

Update Interval
The update interval is the amount of time that a cam window waits before refreshing. You can specifiy this for each cam window in seconds, minutes, or hours by using the properties panel.

URL
URL stands for Uniform Resource Locator. Internet addresses are URLs, and web cams usually appear as an image located at a particular URL. Camembert only recognises the URLs of JPEG and PNG images on the http: scheme.

Thumbnails
The cam windows can be displayed normal size or as thumbnails. A thumbnail is simply a small rendition of the window at the bottom of the screen. Thumbnail windows work exactly like normal windows, and you can right-click on them to get the popup menu as usual. If you have opened many cam windows on your desktop and they are taking up too much space, you can use the Thumbnail All command to 'minimize' the windows by turning them into thumbnails at the bottom of the screen.

Web Cam
A web cam is a camera that is connected to the Internet and accessible from a web page. Some of these provide streaming video and others simply provide a still image that is updated at fixed intervals. Camembert supports the latter type of web cam. The image is usually stored as a JPEG file on a server, and is often seen as part of the content of a web page. Since the image is usually an ordinary JPEG file, it is possible to directly download and display it if you know the URL. This is how Camembert displays web cams. There are a huge number of web cams in existence, although not all of them work properly. The pictures provided by these cams range from pictures of cities, landscapes and buildings, to pictures of insects and animals, to pictures of the inside of people's homes (some of which are adult-oriented).
