Description copied from interface: TextOperations
Cuts the text given by text to the given width with respect to the FontFormat redering data given by fontdata, the transformation given by xform and the text scalings in x and y direction given by textScaleX and textScaleY.

Specified by:
cutToWidth in interface TextOperations
Parameters:
fontdata - the FontFormat to use for the calculation
xform - the transformation to use for the calculation
text - the text to cut
width - the maximum width for the remaining text
textScaleX - the current scale for the text in x direction (view zoom)
textScaleY - the current scale for the text in y direction (view zoom)
keepFirstCharacter - true, to keep the first character of the line, even if it doesn't fit into the width
Returns:
String the cutted text
