Center Strings inside two separate rectangles

1
Hi,
I'd like to display two strings inside two separate rectangles on the same screen. How to center each string inside each rectangle ? I tried DrawFormatedText but this uses the whole screen to center in.

Thank you

Read the help file associated with DrawFormattedText, you can position text anywhere on the screen.

Hi,

there are a handful of functions to help you.

To compute the size or center of a rectangle:
RectSize
CenterRect
CenterRectOnPoint

To compute the size of a text string:
TextBounds
Screen('TextBounds', …)

Be aware that those functions differ in which text 'area' is defined. Their help is worth a look.

Best,

Matthieu

I think having the ability to center or layout strings within an arbitrary target rectangle as requested by the OP would be generally useful, so i added a new optional 11th parameter 'rect' to DrawFormattedText(), which will allow to specify this. Default behaviour is to use the whole target window or texture, as in the past.
