Re: [GRASS-user] d.rast.arrows in high quality plot
Hi Nicolas, Thank you very much! The arrows are thicker now and are visible on the final plot.

Re: [GRASS-user] d.rast.arrows in high quality plot
Hi Niklas, Same for me: the PNG driver draws thinner and thinner arrows when you increase the resolution. If you lower the resolution it's okay though. If you do need such a high resolution (for a poster?), you might try the CAIRO driver (g.manual displaydrivers) which behaves quite differently when producing PNGs. Arrows are drawn with a thicker pen indeed (even at high pixel resolution) but you might be surprised by the raster rendering... and files get very large.

[GRASS-user] d.rast.arrows in high quality plot
Dear all, I'm trying to plot arrows, representing length proportional to magnitude in a printable high resolution map (with d.rast.arrows). Here is what I tried: #!/bin/sh export GRASS_WIDTH=1 export GRASS_HEIGHT=1 export GRASS_PNGFILE=testpng.png export GRASS_PNG_COMPRESSION=0 #export GRASS_RENDER_IMMEDIATE=TRUE export GRASS_TRUECOLOR=TRUE g.region fig_arrows d.mon start=PNG d.rast map=backgro...@permanent d.rast map=magnitude_...@permanent d.rast.arrow map=direction_...@permanent type=compass arrow_color=black grid_color=none x_color=black unknown_color=red skip=12 scale=20 magnitude_map=magnitude_...@permanent d.mon stop=PNG eog $GRASS_PNGFILE& Unfortunately the plotted arrows are quite slim now... is there another solution to achieve this goal?
