Modern image formats can record a lot of additional information about the image within the file itself. This internal data is called metadata. AWC can display some of that metadata as a label on top of the wallpaper. This Preference page allows to to specify what should appear in your label and how it should look.
Here you can set how the label should look. You can set the text colours to use, and where it should appear on the wallpaper
Allows you to select the font and letter size to use when the caption is displayed.
Background and Text Colour
Click on the coloured box to change the colours that will be used to display the caption.
This drop down list allows you to specify where on the screen you want the file name to appear. As well as the obvious top left, bottom centre etc. there is the option to select the position a "smart" basis. This simply means that the position will depend on the position you have selected to display the image. So, if you select Top Smart and your image is displayed on the right hand side of the screen, the filename will appear at the top of the screen and right justified. If you change the image position the file position will change to reflect that change.
This slider lets you set whether the file name is displayed fully opaque or with some level of transparency. You can change it from 100, fully opaque, down to 0 which is completely transparent.
No background (the caption text will be drawn directly onto the image)
The caption text is drawn directly on top of the image without using a coloured background.
Causes the image's filename to be displayed as the caption. You can modify it so that the file's path and file extension are not shown.
Note that if any of the metadata items below are selected then the filename will be replaced by the metadata.
There are a number of ways that an image comment can be stored in a file. JPEG, GIF and PNG files all support a basic file comment field and the EXIF standard defines an ImageDescription tag. AWC first looks for the basic file comment and then, if not found, tries to read the ImageDescription tag.
Note that AWC will let you write file comments to your images but only basic file comments are supported. EXIF data cannot be updated and writing a comment to a file that has an ImageDescription tag will result in a basic file comment being added to the file.
Digital cameras typically store various pieces of information about the image in EXIF data. One of these is called the DateTimeOriginal tag and is the date and time that the picture was taken. If this option is selected the date part of this data will be displayed in your caption. If you have also selected to display the file's comment the date will be added to the end of the retrieved text.
