pngcairo and resolution

[Mojca M. <moj...@gm...>]

Dear list,

The pngcairo terminal behaves a bit weird when setting the size:

gnuplot> set term pngcairo size 10cm,10
Options are ' fontscale 1.0 size 10.00cm, 10.00cm '

gnuplot> set term pngcairo size 10,10cm
Options are ' fontscale 1.0 size 0.35cm, 10.00cm '

On top of that I do find it a bit annoying that I'm not able to check
how many pixels will be the final image size.


Also, the following note is probably not exact:

 The width of all lines in the plot can be modified by the factor <lw>
 specified in `linewidth`. The default linewidth is 0.25 points.
 (1 "PostScript" point = 1/72 inch = 0.353 mm)

>From what I understand the line width is one pixel (which makes it 1
point at 1 dpi).


I would also like to be able to change resolution, but it seems that
this is currently not possible.
