The AWC is designed to do one thing well: allow you to automatically change your desktop wallpaper on a timed basis. The time between changes is defined as a number of seconds, minutes or hours. The displayed image can be stretched or shrunk for the best fit to the screen, optionally maintaining its aspect ratio, or displayed at its actual size. When displaying a picture the user is not limited to the centre of the screen, as is usually the case in windows, but can choose to display it in any of the four corners of the screen or centred on one of the edges. Additionally you can specify that files smaller than a predefined size should be tiled: again you can specify how the tiles are justified on the screen rather than simply going from the top left. Resizing is performed using a range of resampling methods to ensure the best possible results. After resizing you can apply various levels of sharpening to further improve image quality. You can further refine the list of files to display by filtering on file date or age and by file name. For example: all images that you've downloaded in the past 14 days or all files whose name begins 'XMAS' that you've created since the 1st of January 2005.. The AWC is minimised to the system tray rather than to the task bar. To restore it to view just double-click the icon in the tray or right click to pop up a menu. There's even a full set of command line switches so you can customise multiple shortcuts. Image formats supported are *.jpg;*.jpeg;*.gif;*.bmp;*.png;*.rle;*.tga;*.pcx.
