Hi Charlie,
I think, you can do it with rendering multiple images and compare them:
(assuming your sample string "Here is a long string")
- first you render the image you have already in your composition with the
truncated text. (e.g "Here is a lo")
- second image would be the same truncated text but including the complete
word. This will involve some jave script patch to figure out where the current
word will end. ("Here is a long")
- now you can compare the "Line Count"- output of the "Image with String"
patches and see, if they are different.
- if the line count is the same, you are save to use the first image.
- if not, you render only the current word, but truncated, into an image. (just
"lo")
- use the width of that third image to blend the first two images with a
"Swipe" patch ("Width"-parameter = "0")
I didn't try it myself but I am certain this will work.
