Hello,
I have several filters that make use of ThreadedGenerateData . However,
there seems to be some changes in the new version. Is there a place where I
can find the best practice for multithreaded filters (it was not in the
Migration Guide). Thank you.

This is a very basic question, but I don't find how to get the number of
rows and columns from an otbImage. Something like the size in gdalinfo.

Hello again,
Someone kindly provided a solution for OTB 3, but since we moved to OTB 4
it doesn't work anymore. Is there a multiple output writer implemented
somewhere in the ocre of OTB 4.

I still have the problem even after modifying the geotransform to have only

note that OTB also supports vrt file, so you could use gdalbuildvrt instead

Thank you for the tips. Unfortunately it is still not working.
I've downoaded the superbuild tar, changed the download path while

I've also tried to manually download muparser
Thanks Julien for the quick fix: it worked perfectly.

I would try building a mosaic based with gdalbuildvrt, then use the vrt as
input for OTB. Size of image is not a problem in your case. From the
metadatada, you could extract the useful information from the xml files,
which are valid for all tiles.

Have just moved from an old OTB version to a recent one ? If yes, make sure
that your CMakeList.txt use OTBLibraries instead of OTBCommon, OTBIO etc
like in the old versions
