RRD fonts in Windows - what gives ?

[c4ct1m4n]

Hi Folks,

This is my 4th Windows Cacti build and this time I used the lastest installer (from 21st Dec) rather than build manually as I had before. All seems great...

...apart from having no control over the graph fonts anymore.

I've read a lot about other having problems with this from a while ago, but they're all on Linux hosts. I can't find anything re Windows. I've tried what I think is the 'pango' naming (CourierNew, Courier New...).

In the past I've fixed problem with text lining up by changing to non-proportional font.

Any idea where the default font is specified ?

I may be missing something fundamental here, I just don't understand how something that was so easy previously has been made so hard.

Am I missing something ?

Will I break anything by going back to an older RRDTool ?

cheers

Yea, the pango font stuff in rrdtool 1.3 and newer is quite a change from before. However, the Windows implementation still only supports a subset of fonts. The last time I checked, the fonts this rrdtool 1.4.5 build supported are:
"segio ui", tahoma, sans, sans-serif, serif, mono, monospace.

For example when you specify serif, it actually checks the the following fonts in this order: "dejavu serif,georgia,angsana new,mingliu,simsun,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi". When I specify "serif", it opens "georgia.ttf". But it does not scan for any other files. So, it's hitting it on the first pass.

libpango-1.0-0.dll (and possibly a pango wiki page somewhere), contains the full implementation details on what fonts are looked for.

Thanks very much for that BSOD2600, I can see now that there is some control, although clearly very limited.

I've now fixed 90% of the line-up problems using 'monospace'. What I really want is Courier or Courier New, but clearly that's not a question for this forum.

I note that there is no antialising happening, does anyone know if it possible to get antialising or cleartype working on the graphs ?
My graphs remind me of Linux / X11 from the 80's.

thanks

alright, here is the full listing of the fonts checked in order:
courier = "courier new"
"segoe ui" = "segoe ui,meiryo,malgun gothic,microsoft jhenghei,microsoft yahei,gisha,leelawadee,arial unicode ms,browallia new,mingliu,simhei,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"
tahoma = "tahoma,arial unicode ms,lucida sans unicode,browallia new,mingliu,simhei,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"
sans = "dejavu sans,tahoma,arial unicode ms,lucida sans unicode,browallia new,mingliu,simhei,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"
sans-serif = "dejavu sans,tahoma,arial unicode ms,lucida sans unicode,browallia new,mingliu,simhei,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"
serif = "dejavu serif,georgia,angsana new,mingliu,simsun,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"
mono = "dejavu sans mono,courier new,lucida console,courier monothai,mingliu,simsun,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"
monospace = "dejavu sans mono,courier new,lucida console,courier monothai,mingliu,simsun,gulimche,ms gothic,sylfaen,kartika,latha,mangal,raavi"

Screenshot of your aliasing issue? At least looking at my rrdtool 1.4.5 advanced ping graph, it appears as expected (i think).

Many thanks for this, got courier working now.

Your screenshot illustrates my point exactly, your fonts are not anti-aliased.

See below, old install on the left (with "c:\windows\fonts\cour.ttf" looking nice), new install on the right (with "courier" looking jaggy). Both fonts at same size (8):

I just installed RRDtool 1.4.5 (bundled with the Cacti Windows Installer).

And I'm encountering the same issue with no anti-aliasing. Is there a fix?

What pango font is specified to be used?
