Re: [Qgis-user] Batch "ECW creating"
Hello again!
The answer is: for %i in ("d:\\*.tif") do
gdal_translate -of ECW -co LARGE_OK=YES -co TARGET=95 "%i"
"d:\.\%~ni.ecw

Re: [Qgis-user] Batch "ECW creating"
sorry, I did not carefully read .. obviously the wrong answer. But as far as I
understand you need a valid ERDAS license for compression.
Cheers.

Re: [Qgis-user] Batch "ECW creating"
You can read about all of the ECW creation options here:
https://gdal.org/frmt_ecw.html Note that FWTools will likely be using
the old version 3 SDK (or older) for ECW mentioned there.
(by the way, be careful with using abbreviations such as "sth" on
mailing lists, as many readers will not understand what you mean.
Always try to spell out what you are asking for, so those in other
languages can follow easily, giving you more of a chance to get a response)

I would like to use old FWTools 2.4.7 to convert geotiff's files to ecw

Can I add sth to that "command" to achieve better "compression ratio"?
Thanks for any response.

Re: [Qgis-user] Batch "ECW creating"
you might want to have a look for
https://gdal.org/frmt_gtiff.html
search for "COMPRESS=" and decide which compression mode to use, and further
parameter if posiible to control the compression level like for example
"JPEG_QUALITY=", to extend the -co parameter.
Cheers.

Hello!
I am sorry for asking about sth not connected with qgis...
I would like to use old FWTools 2.4.7 to convert geotiff's files to ecw

gdal_translate -of ECW -co LARGE_OK=YES "%i" "d:\.\%~ni.ecw
Can I add sth to that "command" to achieve better "compression ratio"?
Thanks for any response.
