Re: [Gnuplot-info] Gnuplot text scaling problem on Windows

[Teodoro S. <Teo...@es...>]

Hi Tatsuro,

I already register the bug some days ago:
http://sourceforge.net/p/gnuplot/bugs/1613/

I cannot edit it now, do I have to register?
Maybe you could add the terminals affected and the fact that only happens with 125% enlargement.

Thank you for your tests.

Regards,
Teo

I have tested on pdfcairo, wxt, windows, qt, emf png and svg at the moment.
I did not tested epscairo postscript, canvas simply because I have forgotten to test on them.

Affected terminals
wxt, windows, qt

Non-affected terminals
png, svg, emf

pdfcairo does give a graph with your script.

I think that we should register the phenomena into the bug ticket.
