<p>Hi Andrew,</p>
<p>no, there's no such support in GDAL itself. That could
potentially be done using VRT and pixel functions, but I'm not
sure that would qualify as "optimal", and that would require a bit
of setup. You're probably better instantiating your for(y: ...)
for (x: ...) loop manually with the operation you want to apply<br>
</p>
<p>xtensor (<a class="moz-txt-link-freetext" href="https://xtensor.readthedocs.io/en/latest/operator.html">https://xtensor.readthedocs.io/en/latest/operator.html</a>)
(in a nutshell, this is similar to numpy but in C++) could
potentially be used in combination of GDAL, but I don't think we
want to drag this dependency in GDAL itself</p>
<p>Even<br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>Is there any support in the library for applying some
arithmetic operations to all entries in a block? For example,
can I optimally subtract or add some scalar to every entry?<br
