Table 2: GDL Color Attributes
Though there is no attribute for specifying the background color of additional node information
windows, it should be noted that this color is not bound to the RGB constant 255 255 255, but
rather to the value of the first entry of the color map (which happens to be 255 255 255 by
default). Thus, for example, specifying
colorentry 0: 210 218 255
sets the background color for all additional node information windows to alice blue. However, this
color then also appears everywhere else where the color white is used, so you might have to also
specify
colorentry 32: 255 255 255
and use the color number 32 instead of white.
The ASCII formfeed character \f (see p. 109) followed by two digits signifying a color changes
the color for the characters following in a string, thus enabling the first 100 colors of the color map
to be accessed.
5.11 Icons and Additional Fonts
5.11.1 Icons
Instead of text labels, aiSee also offers the option of displaying icon files in nodes. The icon files
have to be in PNG, PBM, PGM, or PPM format (raw). They can be attached to summary nodes
or ordinary nodes by using the iconfile attribute in subgraph (p. 74) or node (p. 94) specifications.
Note: In order to prevent the title text from being drawn over the icon displayed, the label attribute
of the node or summary node has to be set to the empty string, i. e. label: "".
The search path for the icon files can be specified by the environment variable AISEEICONS.
Some additional graph attributes influence the drawing of icons, see icons (p. 74), fast_icons
(p. 71) and iconcolors (p. 74).
5.11.2 Fonts
Apart from the default font, aiSee offers the fonts described in Table 3.
These pixel fonts are compatible with Adobe PostScript fonts. When exporting aiSee files to
