Export button not work FWtools

[ARV187]

Hi, i have a problem with fwtools OpenEV.

With the conversión ED50 to WGS84 the image is rotated and work fine, but to complete the rectangular area is fill with black color, this is normal.

Ok, i use the Draw ROI tool to cut black zone, but the export button not work, why? i try the administrator options & install-work in D: directory, but not fix the problem.

Is possible draw roi in gtiff & export with other freeware program or with a command in Fwtools Shell?

thanks, regards.

Hi,

I never use the OpenEV GUI, so I am not sure if I can help. I always use the command line tools of FWTools.

What are you trying to achieve? Do you want to make the file smaller to get rid of the black border after reprojecting?

That black border is the no data value, so it would not give you trouble in FS.

Thanks arno,
Yes i want cut the black zones selecting with roi tool the interior area.

So, that black zone not is visible in FSX? I thought that only work with a *_B.tif file name for example.

If you put other terrain image (quadrant terrain next) overlapping the black zones, this terrain will work, or he will be transparent because black zone?

Hi again, finally the tif file its with black borders, i will try in fsx.
But, before of that i need resample, ok, i have the georeference image, get the data in ''.gtf'' file, and after put in edited image (blend, night mask...), but not work with fwtools shell, this is crazy, i cant progress.
Here is the steps that i follow.

After I open the georeference tif with a editor (gimp) make the blend colors or night textures, and save with other name, *_B.tif or *_lm.tif
And insert georeferenced data in edited tif, here i have a doubt, if i write

geotifcp -g file1.gtf file1.tif editedfile1_B.tif

i overwrite my edited file with the original file, and undo the edition of file by original tif.
So, i write

geotifcp -g file1.gtf editedfile1_B.tif editedfile1b_B.tif

And is created a new tif file georeferenced in teory, but not...

I think, missing some data, any idea of what is wrong or I'm doing wrong?

Thanks again.

Someone?

Hi,

What you did looks OK. geotifcp -g file.gtf input.tif output.tif.

I don't have a file here now to test it with though.

 

[ARV187]

Hi arno, I have the original file link retroprojected in the first post, to test it.

Reinstall the fwtools not fix the problem. I must try in other pc.
