I am preparing a help/info stack for an ecosystem analysis program.
There are quite a few equations and other small graphics I would like to add to scrolling fields that contains various font sizes, colors etc..(formatted text).

How do you add graphics in a scrolling field. Is this possible, easy. Or should I go a different way ?

Cheers,

Michel

Hi there,

“imageSource” may suit your needs. This lets you assign an image to a character in a field (including scrolling fields). The Rev dictionary gives some examples:

set the imageSource of char 1 of line 2 of field "This" to 2533
set the imageSource of char thisChar of field 1 to "Arrow"
set the imageSource of last char of me to "binfile:My Image"

To automatically allow line space to display an image (which could be considerably bigger than the surrounding text) set the fixedLineHeight of the field to false. You mention your fields contain text of various sizes, so it sounds like the fixedLineHeight of the fields you are using is already set to false, but I thought it a useful thing to mention. I hope this helps.

Edit: another text property worth mentioning is "textShift", which may help adjust the alignment of images with surrounding text. Again, from the Rev dictionary:

set the textShift of last char of word 2 of field 1 to 3 -- subscript
set the textShift of char 12 of the selectedField to -1 -- superscript

Regards,
Michael

or you can also use:

If I have a variable that was filled with a line like this:
I can do this:
But these do not work:
Is there a way to set a character's imageSource with data like this?

Thanks, Jean-Marc.

I thought about that possibility once, but then thought that it would be silly. Makes sense now though. I should have at least tried it.
