[gdal-dev] RGB + Grayscale in gdalwarp

Hi folks, I am trying to merge a grayscale (1-band) image with RGB (3-band) imagery using 'gdalwarp', the hope being that the grayscale image would be converted on-the-fly to RGB by duplicating the one band 3 times, thus ending up still grayscale visually. But 'gdalwarp' doesn't seem to do that;

Jose, FYI, the ReadRaster function is optimized for reading chunks of image, not individual pixels. An array slice is essentially an array itself. But your error message says different. Can you provide the offending lines of code? On Tue, Oct 11, 2011 at 11:19 PM, Jose Gomez-Dans wrote: > Hi, >

Hi, I have installed GDAL 1.8.1 to use the python bindings. I note that if I pass a slice of an array to ReadRaster for the (x,y) pixel location, I get a TypeError: TypeError: in method 'Dataset_ReadRaster1', argument 2 of type 'int' If I surround the offending slice by int( x ) and int(y), it wor

Hi Max, have you tried ogr2ogr -t_srs EPSG:4326 -f "one of many formats" outputfile myshape.shp As ogrinfo recognizes the source shape CS (I guess it has a .prj file associated with it), you should only transform (-t_srs) into the destination CS. All the best Sig > Il giorno lun, 10/10/20
