"raw" format raster images

alobo
Hi!
Any way to open a raster image with no header
for which the user would specify nb. of rows, columns,
bands, bytes per pixel, byte order, bil/bsq/pil, pixel size .... ?

I know can be done through making an envi hdr file, but
want to know if there is any way  to enter the required
data in qgis directly.

Thanks!

Agus

I don't think you can do this directly, but it would be a pretty simple
task to make a basic python script or plugin to do this.

Howdy Agustin,

There is no way to enter these parameters in QGIS directly. You must
make a hdr file.

Basically the raster data are first read by GDAL then QGIS talks to GDAL
and  displays the data for you.
