String rotation

[ellboy]

Hello!

Is it possible to rotate a string using uGFX?

Thanks

Hello ellboy and welcome to the community!

There is currently no API that allows string rotation but we are planing to include that soon. We already added matrix rotation alogrithms to the GMISC module a couple of days ago.

However, there is a small work around: You can change the orientation of your screen, draw the string and change the orientation back again. Note that this method however only works if you have a display controller that does not redraw the framebuffer content when you change the orientation. This is the case with most display controllers such as the SSD and the ILI families.

Would it be possible to use any rotation angles for the strings or limited to some specific?

With the method mentioned above it is only possible to rotate by 90 degrees as your display won't provide any other orientations that than.

When we will implement this feature ourself it will be most likely possible to rotate by 90 degrees as well as by any degree value (the 90 degrees will just be a lot quicker).
