Date Published: March 12, 1995

Problem:

When viewing images in XV, the images appear to be too dark.

Cause:

Pixel!FX and XV perform gamma correction indifferent ways.

Solution:

Do the following to view these images correctly in Pixel!FX and XV.

1) Start PFX with this command : pfx -displayGamma 1.0

OR add this line to the resource file ( $PIXELFXDIR/Pfx ) : -displayGamma 1.0

2) In Pixel!SCAN do a pre-scan and adjust gamma to 2.2

3) Do a final scan with gamma at 2.2.

4) Save the image after final scan.

5) XV will now display the saved image correctly.
