Waveshare 2,8ich TFT Display with library lcd.h turn Text to 90 deg

Hello Comunity

I'm a Newbie in this forum and I have a problem with the TFT-display 2,8 inch from Waveshare.
Does anybody know how to turn a display-string to 90 degrees with the library from waveshare "lcd.h" or has another adequate lib to do this? Thanks to all answers.

Which Waveshare TFT?

Do you really want vertical text?
Adafruit_GFX only draws horizontal text.

Or do you want to run in Landscape mode?

It is possible to render text in 0, 90, 180, 270 degree rotation.
Rendering at an angle is fiddly. And looks horrible.
