[FWTools] gdal_merge with -ps optoin is giving the following error

[mzorova]

ERROR 1: Attempt to create 1x0 dataset is illegal,sizes must be larger than
zero
.
Creation failed, terminating gdal_merge.

the command that causes this error:

[Mon 11/19/2007 15:22:58.60] C:\temp>gdal_merge -v -ps 1480 600 -o
merged.tif 1.tif 2.tif 3.tif 4.tif

I did add two GCP points for each of the 1-4.tif files as well as specified
the projection that they are in.. 

Would anyone have an idea as to what I may be doing wrong here?
