----------------------------------------


Please don't close tickets on your own. We are using the status to indentify all tickets which belong to a specific version if we put the build together.
Further more I'm pretty sure that this improvement will be part of the next 1.8.x release, so that we have to modify some of the properties of this ticket which can't be done if it's already close.

Don't worry, these are just some "internal rules".

> There is a simple way of improving the performance of drawString by replacing
>        string.writePDF( buffer );
>         appendRawCommands( new String( buffer.toByteArray(), "ISO-8859-1"));
>         appendRawCommands( SPACE );
> with
>        string.writePDF( buffer );
>         appendRawCommands( buffer.toByteArray() );
>         appendRawCommands( SPACE );
> as the appendRawCommands(String) simple does a appendRawCommands(str.getBytes( "ISO-8859-1" ));
> Therefore this optimization should spare the String creation as well as the conversion back to a byte array.
