<small>Hi,<br>
<br>
And thanks for your tests</small> <font face="Arial"><small>! For
those who want to make some tests with the same file than me
(tiff</small></font> <small>RGB - 293 Mo)</small>,<small> I
published it on a FTP server :</small><br>
<br>
<small>Adress : <a class="moz-txt-link-freetext" href="ftp://interne.crige-paca.org">ftp://interne.crige-paca.org</a><br>
Login : gdaldevecw<br>
Password :</small> <small>ftc65*gt</small><br>
<br>
<small>I also published in this FTP the comparative table of my
tests and results.</small> <small>I agree with Jean-Claude. It
could be great to make tests with the same original file and the
same gdal_translate command (</small><font size="-1"><font
face="Arial">gdal_translate -of "ECW" -co LARGE_OK="YES" -co
TARGET="90" -co DATUM="RGF93" -co PROJ="LMFRAN93" file_in.tif
file_out.ecw</font></font><small>).<br>
<br>
I made some complementary tests on GDAL 1.9 (Windows-Linux-MacOSX
/ 32-64 bits) and always get the same differencies...<br>
</small><br>
<small>Best regards,<br>
<br>
Sylvain</small><br>

Hi,
<br>
The default TARGET parameter value has been changed from 75% to
95% between GDAL 1.7.3 and GDAL 1.8.
<br>
So please allways give the TARGET parameter when you make your
tests, and use the same TARGET for all your tests.
<br>
<br>
It would be useful if you can make your test image available to
everybody, so that people can compare their results with yours. If
it is not possible, use a freely available image, such as NASA
BlueMarble.
<br>
<br>
Could you also test on Linux 32 bits ?
<br>
<br>
Best regards,
<br>
Jean-Claude
