Hey there,

Anyone know how to determine string length in normalised units when you're using truetype
fonts?

Currently I have:

ch_size = CONVERT_COORD( !D.X_CH_SIZE, !D.Y_CH_SIZE, /DEVICE, /TO_NORMAL )
x_ch_size = ch_size[ 0 ] * charsize
x_length = STRLEN( my_string ) * x_ch_size )

which works great for the regular on-screen hershey type of fonts, but not for proportional
fonts.

any ideas? what I want to do is blank out the plot behind the text, e.g. like for legends etc.
