I asked the following a couple of weeks ago and never got a reply. Frank, can you comment on this please?
. I am trying to remap all "0" value pixels in the source images to the value "1" in the output image using gdalwarp like so: warpOptions->padfSrcNoDataReal[bandIndex] = 0; warpOptions->padfSrcNoDataImag[bandIndex] = NULL; warpOptions->padfDstNoDataReal[bandIndex] = 1; warpOptions->padfDstNoDataImag[bandIndex] = NULL; 1. I am setting INIT_DEST=0. 2. not setting UNIFIED_SRC_NODATA. 3. the source images have no defined nodata value. 4. the output image has no defined nodata value. with no luck. My question is: Is gdalwarp supposed to do this? When I look at the pixel value of the output image the black pixels are still "0" and not "1". My input and output are both 8-bit 3 band images. I am using gdal 1.9.2. Best regards, Martin
