[gdal-dev] clip raster to one cell at coordinates

[karsten]

Hi All,
 
in an application I have a user click on a map and I need to
programmatically clip a raster layer 
to the one raster cell for those coordinates at the click location. 
I was looking e.g. at https://gdal.org/programs/gdal_rasterize.html to run
as a command 
line tool, but so far could not figure out if I can some can "feed" that a
vector point to the tool as an input
without first writing a shape file with the point onto disk. 

Does somebody have any pointers to a command line tool (or a python example)
I could use to achieve this ? 
 
Thanks 
Karsten
