obtaining the pixels and lines from set of geotiffs without fully running gdalwarp

[John Mitchell]

Hi,

I would like to be able to obtain the pixels and lines of a mosaic from set
of geotiffs without fully running gdalwarp to create the mosaic but just to
give me the pixels and lines.  Currently I run gdalwarp -wo
skip_nosource=yes *.tif mosaicfile.tif and cancel it after it says "Creating
output file" and then run gdalinfo to obtain the pixels and lines against
the incomplete mosaic.

Thanks,
