I am trying to make text font size modifiable in a fixed width and height indicator. Can anyone give me some advice on this?Thanks.

I once tried to solve the inverse problem, how to resize a String (or Path) Indicator to fit an arbitrary String whose properties (Size and Boldness, don't think I added Italics) were presented at Run Time (it was made for one-line String/Path displays, but would grow/shrink the indicator as needed). The Picture Control trick didn't work (at least at the time I did this, maybe 4-5 years ago), as the "measurements" from the Pictures were not accurate, particularly as Font size changed. Your situation is easier, as you will change the Font size to make the text fit. You can do this with a String Control/Indicator, whose width I presume you have fixed. The Algorithm is basically to write the String to the Indicator (or Control), with the Enable Wrap property turned on. Now use the Get Nth Line Method to get Line 1 (present if the String is too long and "wraps"), and return its "Start" position. If it is 0, then there is no Line 1, and your String fits (hooray). Otherwise, reset the Text.FontSize property of the String (make it smaller) and try again. Depending on how fast you want this to go and how "exact" you want the fit, you can try various algorithms to adjust how you make the size adjustment. Another trick you can use to speed up the computation is to turn the "Visible" Property of the Indicator off while you are doing this, saving writing to the screen. Bob Schor
