Gflax undesirable compression.

[dbologna]

Hi all,

I'm new in the forum, but i'm glfax user since some years, in FoxPro.
Directo to point.
If you open an image and save it without nothing make; you lost quality in the lumens.
This is the sample:
in.jpg is an image with q=92 and sampling factor 1x1,1x1,1x1 (4:4:4) and the output file has sampling factor 2x2,1x1,1x1 (4:2:0)

ogf=CreateObject("gflax.gflax")
ogf.LoadBitmap("C:\picts\13\in.jpg")
ogf.SaveJPEGQuality=92
ogf.SaveBitmap("C:\picts\13\out.jpg")

Has this any explanation? That I should do to avoid that loss?

Thanks in advance
