FFT Tutorial needs an update

General JUCE discussion

Hi,

The FFT tutorial ( JUCE: Tutorial: The fast Fourier transform ) still makes changes to an image pixel-by-pixel (“setPixelAt”), which is a deprecated behavior because of the Direct2D renderer:

( JUCE 8 Feature Overview: Direct 2D - JUCE ).

Is it possible to update it with code examples that are compatible with Direct2D?

Is there a fast way to make that code run with Direct2D? I’ve tried to set the rendering engine to “software” but there is no difference, the spectrogram is still extremely heavy on the hardware resources.

Thank you.

“Dirty” solution:

spectrogramImage = SoftwareImageType().convert(spectrogramImage);

In the constructor.

Thanks for pointing this out. It’s being updated.
