[Gnuplot-info] generate png file yet complaining gdImageStringFT: Could not find/open font ...

[Jon <dev...@gm...>]

Hello Guys,

I tried to generate png file. I firstly tried

convert aaa.eps -resize 640 480 aaa.png

outside gnuplot, but the plot is smeared out due to magnification.

So, I tried to generate png file within gnuplot using set term png, but it
complains

gdImageStringFT: Could not find/open font while printing string Experiment
with font Times-Roman
gdImageStringFT: Could not find/open font while printing string Experiment
with font Times-Roman
gdImageStringFT: Could not find/open font while printing string Calculation
with font Times-Roman
gdImageStringFT: Could not find/open font while printing string Calculation
with font Times-Roman
...

I did some google search and found that it could be that png cannot find the
required path to the font, so I included the path as the following,

set term png font "/home/.../fmaker55/fminit/fontdir/Times-Roman.pfa" 12
enhanced

this is the only Times-Roman file I can find in the computer with ttf or pfa
surrfix.

But it still complains the same thing.

Any idea to help me solve the png generation problem?

Thanks a lot!

Sincerely,
Jon
