DrawRadialText for Fenix 6X?

CLA over 1 year ago

How to draw text along a circle (like drawRadialText()) with a 3.4.0 system (Fenix 6X), knowing that this API is only available in version 4.2.0?
FYI, there is at least one watch face that allows you to do this (B65 Fusion 1 for example, Fenix7 Pro3 MB, Infocal V2) and which works on the Fenix6.

Well, I found an old post ("Text in circular shape") from 8 years ago in which I think I have my answer.
This post led me to another post written by ftromboli ("My technique for anti-aliased animation and bitmaps") in which he explains that he uses the now classic technique of fonts to draw an animated shape (Mickey in his example).
In short, all you have to do is create a character font in which each character will have had a rotation of a certain number of degrees and that's it!

Thanks ftromboli!

hi, I don't know if you talked about this post, but see here: https://forums.garmin.com/developer/connect-iq/f/discussion/195648/tilemapper-tool-for-tile-mapped-anti-aliased-graphics

Ftromboli offer a soft to do so.

Thanks, but I need to draw numbers instead, not shapes.
This is my actual prototype. See steps indicator.
In fact, I wonder if I really need to rotate numbers.
Do you think the result is acceptable for the step indicator?

well on my side it is acceptable, but I think you will have many feedback about this. what I did on mine, for exemple for your steps position is to create only 1 font roated 45° counter clock. but it is up to you, creating custom font takes a lot of memory

The source code for Infocal is on Github, I think you'll be able to see how it's done from there. https://apps.garmin.com/en-US/apps/c97c4e34-55e4-4601-b5c2-45763bc481a2#0 https://github.com/RyanDam/Infocal

Already answered I see, but it’s simply a case of applying basic maths of x,y centre, radius, angle and the cosine and sine functions to calculate the x,y coordinates for your text on a circle.
