Text Box

What do you mean by "Mark Up" ? Are you referring to Hyper Text Markup Language (HTML)?

Here is a text box with vertical text done in Word if that is what you mean. You could also just type in a text box, save the text box as an image and rotate the image.

Please provide more details about what it is you want to do.

How do I change the direction of the text in Mark Up...for example, I want to change the text to vertical or on a slant.

You cannot change the orientation of the Text Box in Mark Up in Photos (iOS & macOS).

If you do make the size of the text box narrow enough ... the text inside will wrap to adjust and appear vertical!

For slant ... sorry!

Looks like I missed the mark. I think Siabh likely has the answer.
