Hi
I would like to reshape a ECW pictures in several tiles.
Would it be possible to translate ECW in VRT; cut the VRT in tiles, and
re-translate all VRT in ECW?
And if it's possible, what are the syntax for those commands?
Thanks

OK. So I try using this size for each tiles 128*128.
The treatment is very long.
So is it possible with GDALBUILDVRT, to translate virtualy the ECW in
another format; cut in several tiles; and then re-translate each tile in
ecw?

Hi,
Why do you talk about million pixels?
I'm trying now with this command:
gdal_retile -of ECW -ps 1000 1000 -targetDir C:\GDAL\ECW Image.ecw
It's not finished yet, but there's so many tiles!!
I thought maybe using gdalbuildvrt, it could be a possibility.

Hi,
I try to cut an image in several tiles.
I use this command:
gdal_retile -of ECW -ps 1 1 -targetDir C:\GDAL\ECW Image.ecw
I obtain 4 tiles, but after I've got this message:
"Traceback (most recent call last):
File "C:\PROGRA~1\FWTOOL~1.7\bin\gdal_retile.py", line 941, in ?
sys
her tools, such as pct2rgb.py or "gdal_translate -expand
RGB" to operate gdalbuildvrt on RGB rasters instead.
The reason the red areas were occuring in different areas is that gdalbuildvrt
considers only the first file's color table.

I think more about the value of data.

But it's not always the picture on the right which pixels become red; it can
be also the picture on the left.
I have the felling it depends on the range of merging.

But a part of the picture gets a lots of red pixels.
Does someone know why?
Thanks
