Hi Andreas,<br>
<br>
You can use the QFieldSync plugin which comes with a processing
algorithm that renders a styled map within a given extent to a
raster dataset.<br>

<div dir="ltr">I feel I am missing a basic function
somewhere to "burn" (in gdal terms) a vector layer as
styled by QGIS, for example with labels, to a raster layer
(of some resolution).
<div><br>
</div>
<div>The Rasterize (vector to raster) function is based on
gdal_rasterize and does not take into account styling as
it focuses on preserving the actual data.</div>
<div><br>
</div>
<div>The work around I am currently using is to use
Project-Save as Image while displaying only the styled
vector layer which will generate a correct world file
helper, then loading the generated image as raster layer
and assigning the correct projection. Finally, I clip
the raster with the original extent of the vector layer.</div>
<div><br>
</div>
<div>This works but is limited as the resolution is
constrained by the physical size of the map window and
requires the additional house keeping steps.</div>
<div><br>
</div>
<div>qgis2web or QTiles or OGR2Tiles as plugins do
something like this internally but I could not find a
plugin which just generates a regular raster layer (say
geotiff).</div>
<div><br>
</div>
<div>I also know I could probably produce a short Python
script (perhaps as processing script) to do this but
still think I am missing something ?</div>
