Usually the logos are copied into logo-xxxxxx.png where xxxxxx is
the name of the logo. When you use a base=foo attribute, then the
resulting files are named foo.logo-xxxxxx.png. Actually you can even
use a complete filename including a directory prefix, i.e. when you use
base=../../common/foo attribute, then the images are created as
../../common/foo.logo-xxxxxx.png.
And for most flexibility when no base is specified and the variable
LOGO_BASE is defined (usually from within a .wmlrc file via
-LOGO_BASE~path/to/logo/dir/base) it is used. Use this feature to
copy the logos to a particular directory.
You may also use the variable IMAGE_BASE which defines in a single line
all base names for images generated by WML.
Logos are available in PNG or GIF formats. This attribute is the
filename extension of the desired format, i.e. respectively png and gif.
Default is png extension ; this default can be changed via the IMAGE_FORMAT
variable.
This forces <logo> to expand to nothing, i.e. no resulting
<img> tag. The image itself is still generated. In combination with
the above file attribute this can be used to generate images to particular
files which can be used at other positions, for instance inside
<rollover> (see wml::des::rollover(3)) tags.
For backward compatibility a logo named "php3" is also available.
Inluding the version number was not a really good idea, use the
logo "php" instead. Expect that the logo "php3" will be removed in
future releases.
