[gdal-dev] gdalwarp - Clip raster using mask

[Alisson Barbosa]

Hi friends,

By using gdalwarp to clip a raster with a mask (shape), I get a new raster
of smaller size, which is the boundary of the polygon shape (mask).
However, the pixels do not pass the polygon. I would like to pass the
pixels just a little of the polygon mask.

For clarity, I send two pictures of what I desire and not desire:
http://postimage.org/image/hlrc3911z/
http://postimage.org/image/4vn3q5t3r/

The used command is: gdalwarp -dstnodata 0 -q -cutline
C:/Users/Hugo/Final.shp -crop_to_cutline -of GTiff
C:/Users/Hugo/Elevation-DEM-CLIPPED.img
C:/Users/Hugo/Elevation-DEM-CLIPPED.img

Can you help me?

Best Regards,
