[gdal-dev] Gdal_edit and TIFFTAG_EXTRASAMPLES

Hi, I have been searching an easy way to change the interpretion of 4-channel images between RGBA and RGB+undefined. Wouldn't if be useful to make gdal_edit to support also changing the TIFFTAG_EXTRASAMPLES metadata? Or do we have some other easy way for performing that task? -Jukka Rahkonen-

Re: [gdal-dev] Gdal2tiles gains parallel processing features

Jeremy, From a quick look, both should be achievable: - GeoPackage output: I guess you ask because of multiprocessing ? Otherwise a plain gdal_translate will do ;-) Multiprocessing brings the interesting question of write concurrency with sqlite3. So I think "manual" writing with sqlite3 low

Re: [gdal-dev] Gdal2tiles gains parallel processing features

Hey Jeremy, I would say I don't know anything about GeoPackage or tile grids profile. What I can say: - the new version only brings parallelism to the script - because of the rewrite, I would hope anything to be slightly easier. Cheers --- Gregory Bataille On Fri, Sep 29, 2017 at 9:24 PM,
