This function is part of the Pango library.
Syntax
INT pango_render ( <STRING markup> )
Description
Returns a graphic with the specified markup rendered on it. The markup is expected to be a UTF-8 encoded string; markup accepted by the Pango BennuGD binding is the same as upstream Pango's and can be consulted here.
In case of failure, a 0x0 sized graphic will be returned.
After usage, unload the graphic with map_unload().
Parameters
STRING markup | - The markup to render to a graphic. |
Returns
INT : GraphID
0 | - There was some error. Pango tends to drop error on stdout, so check your terminal for them. |
>0 | - The graphID of a new graphic with the specified markup rendered on it. |
