I am using QGIS version 3.2.3-Bonn on Windows 10.

I have downloaded the global physical map raster from Natural Earth link. This is in WGS84, and I wish to project it as World Robinson (ESRI:54030), but when I do so the map repeats in the corners (see screenshot). I wish to create a PDF without the corners being repeated. How can I do this?

I have tried: - Changing the project CRS to World Robinson and enabling 'On The Fly' projection. - Reprojecting the file to the World Robinson CRS, using raster -> projections -> warp (reproject).

Both approaches result in the corners of the map being repeated.

How can I simply show the map reprojected, without any part of the map being repeated?

World map with CRS WGS84 Same map with World Robinson CRS (ESRI:54030). See repeated map portions in the corner QGIS Print Composer has same issue of repeated map portions in the corner

Use the gdalwarp command to generate a new raster file reprojected to EPSG:54030.
You can find it in:
- Raster menu, Projections, Warp (Reproject).
or in
- Proccesing Toolbox, GDAL, Raster Projections, Warp (Reproject).

  You can use the GUI: Warp

  The code is something like:
gdalwarp -s_srs EPSG:4326 -t_srs EPSG:54030 -dstnodata 0.0 -r near -ot Float32 -of GTiff C:\NE1_LR_LC.tif C:\NE1_LR_LC-54030.tif

  You can adjust it to your needs, the result is something like this picture (black is no data):
54030

  Edit:
This is the result, the raster layer added, in QGIS Bonn
Warped

    Thanks @Gabriel for your answer. Unfortunately, I tried: Raster menu, Projections, Warp (Reproject) in my original attempt. I have tried again and still get the same result. I.e. I reproject the original WGS84 raster into EPSG54030 but the corners are still reproduced, as in my original email. I have tried viewing the resultant files in both QGIS 3.2.3 and QGIS 2.18.14, and the corners are still being reproduced. Would you have any other suggestions?

    Reproject the image with gdalwarp, export the new raster layer, open the .tif file in some image viewer. The .tif file has the reproduced corners? If so, share the gdalwarp code and a link to the compressed image file. If not, create a new project and add the raster layer, there is no reason for QGIS to reproduce the corners in that case.
