# Frame ticks not magnified along with plot

I am using Mathematica 11.0 under Linux.

I want to export some plots in PNG format, with resolution higher than the notebook display resolution.

When I evaluate

Export["filename.png", Magnify[plot, 2],"PNG"]


this gives me a good resolution, but the frame ticks from the plots are gone after magnification. I want the output in PNG format as I might need this figures later to assemble with other existing figures as an inset.

Is there a smarter way to improve the image resolution?

I have tried increasing ImageSize, but it does not help. Also, I have tried setting ImageResoltion up to 2500, but that does not help either.

### Update

When I make a plot (say a list plot), I always use Frame-> True and FrameTicks -> Automatic. The frame ticks are visible when I export the plot as PNG without any magnification. However, the frame ticks are not visible when I use

Export["filename.png", Magnify[plot, 2],"PNG"]

• I know that you do not have issues with my code, but that is not my question. – PythonNoob Dec 13 '16 at 22:57
• In that case I have no idea what is your question. You say "frame ticks are gone", but I don't replicate this. – corey979 Dec 13 '16 at 23:02

The issue is real, but has nothing to do with Export. It is a problem with Magnification alone. Running V11.0.1 on OS X, I can reproduce the problem in my note book as follows:

 plot = Plot[Sin[x], {x, 0, 2 π}, Frame -> True]


Then

 Style[plot, Magnification -> 2]


The frame ticks are not magnified along with the rest of plot. I consider this a bug.

• Thanks a lot; Yes, I guess its a magnification issue. However, in my case I do not see frame ticks at all (after exporting the magnified image) when I open the "PNG" in softwares like "gwenview". Anyways, the problem still persists. I need a high resolution plots in "PNG", which seems like an impossible task with Linux supporting Mathematica 11.0. – PythonNoob Dec 13 '16 at 23:54
