Transparent caption text

Hi folks!

I was wondering if it is possible to make a caption text fully transparent.
Image

http://www.imagemagick.org/Usage/text/#caption_bestfit

Code: Select all

convert -background lightblue -fill blue -font Candice -size 320x140 \
          caption:'This text is resized to best fill the space given.' \
          caption_filled.gif
I tried with -fill none and didn't have any success.

What would be the correct method?

Thank you

Thank you snibgo!

I tried the code and unfortunately it just gave a red canvas.

I will attempt to upgrade my imagemagick on Ubuntu and try this again.

Cheers
