Hi Slawek!

Try checking the texture mapper example from the TouchGFX 4.10.0 designer. You can see in code how to rotate an image (e.g. an indicator on a knob). The texturemapper will be supported by the 4.11.0 designer.

Let me know if you need more pointers.

Best regards,

Martin

This is a feature I would like more information on.

When will 4.11.0 be released?

Hi @scottSD​,

4.11 won't be released since we've been waiting on internal deadlines. We've managed to get 4.12 ready in the mean time which will be out by the end of this month.

That being said, the texturemapper is still available in the framework, just not through the designer. check our some of the UI templates for how to use the TextureMapper. When loading the example you won't see anything on canvas since it's all handled in code.

I have experimented with the animatedTextureMapper and am pleased with what I am seeing so far. A lot of my application will require the rotation of images, so I am excited about the possibilities. The only complaint I have is lack of detailed documentation on the "TouchGFX Doc Site" on some of its features (the value of Z angle, for example). I ended up conducting a lot of trial and error to determine its functionality.

Looking forward to it being part of the Designer.
