Re: [gdal-dev] RGB to PALETTE conversion
Thanks Chris Smemoe and jratike80, I found a solution, thanks to you both. I create my palette image in photoshop, then with gdal, I create my VRT fron that image and then, all my next images with the same colors with rgb2pct... Like a charm. If you know best approach, please let-me know. Thanks, once again! -- Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html ___ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev

Re: [gdal-dev] RGB to PALETTE conversion
Paulo, Are you trying to convert a file with multiple bands (RGB or RGBA) to a file with a single band and a color palette? One possible solution showing how to do this using GDAL is shown on Stack Exchange at the following location: https://gis.stackexchange.com/questions/246045/export-geotiff-with-color-tab le-from-web-service-using-gdal-translate/259414#259414 Somebody might have something better. I imagine you could use a similar solution to handle CMYK images.
