Does PhotoLab show file size in memory?

DxO PhotoLab

As I told, my first count is in bits and then divided by 8 to get a Bytes result.

I write it again :

size bits = x pixel * y pixel * bitdepht * number channels (3 for photolab : rgb).
size bytes = size bits / 8.
size kB = size bytes / 1024.
size MB = size kB / 1024.

But this is not the size of a jpg image. This is the size of an uncompressed image used in memory for processing for example.

A JPG is a DISK file. It’s the storage of the in-memory RGB raster image. This can be done in different ways.
When loaded in memory this file is decompressed and stored as a RGB raster image. The question has all ways been how big is that RGB raster image.

So we’re both right. No ?
