wml::std::logo - Logo Insertion

 #use wml::std::logo

 <logo [attributes]>

This include file provides the CW<logo> tag to insert logo images. The logo is selected via attribute CWname. The following logos are available:

The CWname attribute selects which logo is wanted. The table above lists valid names, and wml is used by default. Usually the logos are copied into logo-xxxxxx.png where CWxxxxxx is the name of the logo. When you use a CWbase=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 CWbase=../../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 CWLOGO_BASE is defined (usually from within a .wmlrc file via CW-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 CWIMAGE_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 CWpng and CWgif. Default is CWpng extension ; this default can be changed via the CWIMAGE_FORMAT variable. This attribute defines the logo filename. It overrides all other computed values. If the CWtarget attribute is used, it refers to a target frame or window where the hyperlink is redirected to. This forces CW<logo> to expand to nothing, i.e. no resulting CW<img> tag. The image itself is still generated. In combination with the above CWfile attribute this can be used to generate images to particular files which can be used at other positions, for instance inside CW<rollover> (see wml::des::rollover(3)) tags.

This example only copy the vim logo to CW$(IMAGES)/logo-vim.png without any output:

 <logo name=vim format=png base="$(IMAGES)/logo" notag>

 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.
