[FWTools] help converting format

[Benoît Andrieu]

Dear Carlos,

Yes, you should open a FWTools shell or set the FWTools path in your 
PATH environment variable.
And yes, the command line should be executed in the directory where your 
images are but you can easily customize his behaviour :

    mkdir __your_path__\converted
    FOR %%g in (__your_path__\*.tif) do gdal_translate -of JPEG
    "__your_path__\%%nxg" "__your_path__\converted\%%ng.jpg"

The first line will create a new folder in your folder.

FOR %%g in (__your_path__*.tif)    ===> This will select all the files 
in your directory and iterate with the %%g variable
"%%nxg"                            ===> n = name of the file without its 
extension, x = extension of the file, g = the name of the variable
"%%ng.jpg"                         ===> This will change the extension 
of the file

Regarding the binary format, could you tell me more about the file you 
sent ?
I would need its width, height, number of bands (gray, RGB, ARGB ?) and 
the data type of each pixel (Byte, Int16, Float32 ?).
Thanks.
I would use the GenBin format too but unfortunately, GDAL is only able 
to read them...

*_To the list :_*
You can find the file sent by Carlos at this address

Best regards,
Benoît Andrieu
