#413 Support for vector graphic formats when plotting an image

[theo_keane]

Hello,

Support for vector graphic image formats, such as .svg .eps etc. would be highly useful when inserting images in plots. Currently, if you wish to scale down the size of an image, the quality of the scaled down images is poor. Vector graphic formats would not suffer from this problem.

What is your request, exactly?
Gnuplot already supports output to svg, eps, pdf and other vector formats, including image plots.

I mean vector formats when plotting an image from a file, e.g. plot
"picture.eps" with rgbimage
As far as I can tell, gnuplot currently only supports bitmap-type formats
for this purpose, though I may be mistaken?

Sorry, still not sure I understand what you are aiming for.

Is the idea that for example when using gnuplot to create a new svg file you would embed a reference to an existing svg file as part of the output? That might be possible. But I can't off the top of my head think of an equivalent for eps or pdf.

Yes that's right: for example a multiplot containing one plot, a graph, and
the second, a small watermark in the corner.
