Hi,

Does anyone know if setting the compression of an image to a PSNR, i.e. compress the image to 70 PSNR whether it is lossy compression?

I have seen contradictory write-ups on this. To my mind a lossless image has it's own PSNR. If it is set to 70 PSNR then it could potentially have to lose data to reach that PSNR.

I could be wrong, might have misunderstood PSNR.

Any help is appreciated.

Thanks,
