watermarking.
-Preference
-Default Value

-None
-The text you would like shown as the watermark. Typically this will be a
-copyright notice.
-**wm_font_path**
-None
-None
-The server path to the True Type Font you would like to use. If you do
-not use this option, the native GD font will be used.
-**wm_font_size**
-16
-None
-The size of the text. Note: If you are not using the True Type option
-above, the number is set using a range of 1 - 5. Otherwise, you can use
-any valid pixel size for the font you're using.
-**wm_font_color**
-ffffff
-None
-The font color, specified in hex. Note, you must use the full 6
-character hex value (ie, 993300), rather than the three character
-abbreviated version (ie fff).
-**wm_shadow_color**
-None
-None
-The color of the drop shadow, specified in hex. If you leave this blank
-a drop shadow will not be used. Note, you must use the full 6 character

Overlay Preferences
-------------------
This table shown the preferences that are available for the overlay type
of watermarking.
-Preference
-Default Value
-Options
-Description
-**wm_overlay_path**
-None
-None
-The server path to the image you wish to use as your watermark. Required
-only if you are using the overlay method.
-**wm_opacity**
-50
-1 - 100
-Image opacity. You may specify the opacity (i.e. transparency) of your
-watermark image. This allows the watermark to be faint and not
-completely obscure the details from the original image behind it. A 50%
-opacity is typical.
-**wm_x_transp**
-4
-A number
-If your watermark image is a PNG or GIF image, you may specify a color
-on the image to be "transparent". This setting (along with the next)
-will allow you to specify that color. This works by specifying the "X"
-and "Y" coordinate pixel (measured from the upper left) within the image
-that corresponds to a pixel representative of the color you want to be
-transparent.
-**wm_y_transp**
-4
-A number
-Along with the previous setting, this allows you to specify the
-coordinate to a pixel representative of the color you want to be
-transparent.
