ESP32 Forum

Hello there,

Is nearest-neighbor (integer) scaling available with the PPA on ESP32P4?

I am currently using an integer scale factor of 4, but the scaled bitmap appears filtered/blurry.

Sorry, the PPA uses a fixed bilinear scaling algorithm. I agree that nearest-neighbour would give better results for some imagery; I'll ask the digital team if they can add it to the PPA in any future chips.
