out format options with osgearth_conv

[christ0phd]

Hi all,

is there any way to set file format options via oagearth_conv for the output file. Currently the tool writes out 4 samples/pixel but I want to set it to 3 to stop the TIFFReader from complaining about "Sum of Photometric type-related color channels and ExtraSamples doesn't match SamplesPerPixel. Defining non-color channels as ExtraSamples.."

Hi Christoph, can you post an example of your osgearth_conv command line? We normally use PNG, JPG or DDS as the output format from osgearth_conv so haven't ran into that since we don't export imagery as tiffs.

Hey Jason, I used the following call:
osgearth_conv --in driver GDALImage --in url input.tif --out driver TMSImage --out url outdir/tms.xml --out format tif
While the input.tif is 24bpp RGB image the resulting tifs in the output directory are 32bits. I tried to extend the call by --out TIFFTAG_SAMPLESPERPIXEL 3 and by --out TIFFTAG_PHOTOMETRIC PHOTOMETRIC_RGB. Both additions were mentioned in the output message of osgearth_conv. But nothing changed the files in output directory.
