How to change font size gradually with animation during the runtime using touchgfx designer?

[miresu]

Hi

I'm trying to make a text that gets bigger automatically with smooth animation.

Is there any way to make it happen using touchgfx?

I tried, but I couldn't find a good way to implement it.

I tried to make two typed text (one bigger, one smaller), but switching these two seems too unnatural and awkward.

Is there any way to dynamically change font size with animation?

Hello @miresu ,
 

Its not possible to change the size dynamically since the font is compiled, but you could try to use a bitmap image in a texture mapper, then you will be able to do the animation you want to.

 

BR,

Sorry to bother you again, but my co-workers have some more questions to you.

We bought STM32U5G9J-DK1, and we turned it on.

There was a demo firmware running in it, so we decided to look into it.

What we found was that there was "Font" menu, which has dynamic animations. (like characters getting bigger, rotating and stuff)

What my co-workers are curious is that since it has name "Font" on it and there are documentations about vector fonts, we should be able to make it happen during the runtime.

Can you answer us again about this please? Thank you.

Hello @miresu.

I realize that your question is quite old, so first of all I apologize for the very late response.

You are correct that vector fonts are animated in the font demo within the Out-of-Box demo for STM32U5G9J-DK1. However, this functionality is implemented using NeoChromSDK rather than built-in TouchGFX features. Currently, the TouchGFX text area widget does not support font animation of this type.

If you do not already have access, you can request access to NeoChromSDK by contacting [e-mail].

Best regards,
Johan
