Hi there,
Im wondering if there could be a way/hack to apply a lut to an image with juce current tools,
ideally at ‘paint’ time by gpu (looks like ie direct2d could potentially allow this?)
idea for ex would be:
hold specrogram images as single channel (BW containing magnitude datas).
(so less RAM/CPU)
then be able to ‘remap’ for ex the 255 grayscale values to different ARGB color maps.
that could also allow to easy make color correction/palettes effects ect…
could be powerful maybe at ‘graphic context’ level
I know i can do that iterating with bitmapData, but that seem very cpu consumming for big arrays
so had this wonder…
