It's not so easy to follow what is "desired" and "not-desired". For
an excellent discussion of the details involved in such operations

As a solution for your 'wish-behavior' case maybe what you can do
is to previously expand your polygon with a buffer of half cell
width. <br>

<div>Hi friends,<br>
<br>
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.<br>
<br>
For clarity, I send two pictures of what I desire and not
desire:<br>

The used command is: gdalwarp -dstnodata 0 -q -cutline
