[Gdal-dev] gdal_transform converting jpg to tiff

[br]

Hello,

having .jpg files along with equal named world files .jgw (same format as
.tfw) I try to convert these jpg's to tiff

gdal_transform x.jpg x.tif

(using gdal 1.4)
the result is a 192 MB .tif file (from a 10 MB .jpg)

but the most annoying thing is that the result is grayscaled and the content
is warped into a rectangle at the left border of the square.

Is the command line just to simple for doing the job?

Thanks for listening,
Bjoern
