If you use a raster with a signed data type, that could be negative
values (assuming I understand your question)
ah I see, arbitrary integer values map to a colour 0:(n-1) colours,
Hi,

come to the conclusion that the Windows heap allocation mechanism sucks.
Basically if you allocate a lot of heap regions of modest size with
malloc()/new[], the time spent when freeing them all

It turned out that I didn’t specify swig_executable and an old version of swig
was used on linux build. After fixing this, the warning was gone.
Back on windows build, with swig 4.2.1, python 3.12.2, setuptools 69.2, cmake
still couldn’t install python binding. And I have to manually invoke

Hi, Even.
Using both options "-optim raster" and "-optim vector" results in the same
size files. This is expected, since, as follows from the option description, it
only affects the rasterization algorithm.

Subject: Re:
"cmake --build . --target gdal_GEOR" should shorten a bit the build
time. It will try to rebuild the main "GDAL" target, but if it is
already up to date, that should be just a matter for the build system to
check that no files need to be rebuilt.

It would be nice to have an open option to substitute a string of text
with some other value, treating .vrt something like a template. Such as:
-oo REPLACE="'sourceString'='targetString'"
Thoughts? Thanks for listening!

FYI, for those interested in GeoParquet,
