determining size of drawn text

[John Alexander-7]

Hi everyone -

I am using the drawString() function to print the name of the path/file
I am processing.  The image I am drawing on is of a known size (1300
pixels wide).

The problem is that on occasion I run across a file whos path/name is
longer than the width of the image - and so much of it is not seen.

Currently I use SansSerif size 18.

I would like to calculate the width in pixels of the text string first,
and if it is greater than 1300, use a smaller font size.

Is this possible?

John

Use the getStringWidth(string) function, which returns the width in
pixels of the specified string. This function has existed for a long
time but it was not on the list at
http://rsbweb.nih.gov/ij/developer/macro/functions.html until today.
