Style = CreateObject("java", "java.awt.Font").PLAIN;
} else if (Style EQ "Bold") {
Style = CreateObject("java", "java.awt.Font").BOLD;
} else if (Style EQ "Italic") {
Style = CreateObject("java", "java.awt.Font").ITALIC;
}
This is a waste you can just pass on int value in so you coul just do
something like this (sorry it isn't in cfscript its a copy and paste
job from my function):
<cfswitch _expression_="#arguments.style#">
<cfcase value="plain"><cfset font_style = 0/></cfcase>
<cfcase value="bold"><cfset font_style = 1/></cfcase>
<cfcase value="italic"><cfset font_style = 2/></cfcase>
<cfcase value="bold italic"><cfset font_style = 3/></cfcase>
<cfcase value="italic bold"><cfset font_style = 3/></cfcase>
<cfcase value="bolditalic"><cfset font_style = 3/></cfcase>
<cfcase value="italicbold"><cfset font_style = 3/></cfcase>
</cfswitch>
That will elminate an object creation right there.
Also for each page request only create the font objects as many times
as there are different font,style,point combinations...that should
also trim down the # of time the object is created.
