Hi,
I'm try-ing to merge some tiff4 raster.
The call I'm using (thx Frank and Etienne) is these:
python gdal_merge.py -o ../raster/raster_1.tif -n 0 -ot Byte -pct
../raster/raster_1/*.tif
gdal_translate -co NBITS=1 -co COMPRESS=CCITTFAX4 -co TFW=YES
../raster/raster_1.tif ../raster/raster_2.tif
I firstly merge they with gdal_merge.py and after I translate they in a
CTTIFF4 1 bit color.
On a little test it work very well.
But when I apply it to all set of raster it give me this memory error.

I don't know if this is a know issue or a problem of python configuration.
I'm working on a windows7 64 bit, and I'm using a gdal 64bit version.
