[gdal-dev] GDAL Image Viewer supporting extensions

[Ledoux, Bruno]

Thanks for the pointer on QGIS, we will try.

I was mentioning geotools because we already use it in a thick client to display images. Eventually, we will have to integrate our format into geotools but I am looking for an alternate and quick way to do some tests.

Regards,
B. Ledoux

Bruno,

Not sure why you mention Geotools, which is a completely different technical code base.
Anyway for GDAL, once your driver is developed, using a GUI that relies on GDAL to display your format should be pretty easy. For example you can use QGIS. You just have to make sure to compile against the headers of the GDAL version used by QGIS, and then add your plugin shared object in the path searched by GDAL_DRIVER_PATH. This is how OSGeo4W works for the proprietary formats (ECW, MrSID, etc...) On Linux, you can also completely substitute the GDAL shared object used by QGIS with your own, by tweaking LD_LIBRARY_PATH and doing the right symbolic links (e.g "ln -s libgdal.so libgdal.so.X.Y.Z" where X.Y.Z is the version expected by QGIS) Same applies for OpenEV, but the latter is probably a bit more difficult to build now.

Best regards,

Even
