Awula,
By default, PCI applies a contrast stretch
to an image on load. ArcGIS only applies an automatic contrast stretch to .img
format images. To apply a contrast stretch manually, go to the layer properties
-> Symbology –> Stretch -> Standard Deviations. Generally the
image looks better if you also choose the option “Statistics: From the
current display extent”

Awula,
Try building image statistics in Arc for
each channel in the pix file.

Subject: Do I need a pix raster
plug-in to ArcGIS?
Hello everyone.
I am using
ArcMap version 9.2. I have pci pix format images. I created these from merging
different bands (using the Translating and Transferring
Utilities in Focus) When I view them in ArcMap they look dark and visually not
good, no matter what bands I chose for the RGB. However the view looks good in
PCI. What am I doing wrong? Do I need to instal pix plug-in to ArcGIS to
correct this or such a recent version of ArcMap should already have it? Or is
there a better way of combining the various bands into one image? Please help.
Thank you.
