[rrd-users] UTF-8 encoding + transparency

[George Andonov]

Hello,

I have two questions regarding RRD graph.

1. How to change the font encoding?
I want to set the Title in Cyrillic alphabet (UTF-8 encoding).
Example (written in UTF-8):
     rrdtool graph test.png \
     ... \
     --title "Ала бала портокала" \
     --font TITLE:13:/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf \
     ...
But the Title is printed in ISO-8859-1in the PNG file.
With -- font I can change the font, but I don't know how to change the
encoding.

2. How to add "transparency" to the area?
Quote from the documentation:
    ... Additionally you can add an alpha channel (transparency). The
default will be ``FF'' which means non-transparent. ...
Please provide some examples.


Thank you in advance.
