area combination fails when fixing contour plot

[kzhooou]

brilliant script for fixing annoying white lines
but not working when I tried to fix the artifacts between areas (MatlabR2017a)

[Conclusio]

Could you please provide an example .eps file for your issue? I.e. the input file before calling 'epsclean'.
Otherwise I cannot really reproduce the problem.

Thank you.

[kzhooou]

Original.zip
Please see attached the original eps. Thanks ever so much that your script already helped a lot without the area combination

[Conclusio]

Thank you for the input.
I cleaned your file with R2016b cleaned.zip.
Please check if that is the expected result.

As of now, I do not have access to another Matlab version.
What exactly happens in your MatlabR2017a version?
No file created?
Broken file created?
Artifacts remain?

[kzhooou]

This is the same as what I've got from the combination option being set 'false', while the gaps between areas of different colours remain.

Or maybe do I misunderstand the effect of the option to combine areas?

[kzhooou]

with 'combineAreas',true, it ran for 9010.899407 seconds and generated a broken file

I see...
So, combineAreas combines only areas of equal colors/properties. That means the lines between different shaded areas will not disappear. But, I have a solution for you.

In the "cleaned" file, change line
/f/fill ld
to
/f{GS 1 LW S GR fill}bd
and move it below the /LW... line

This eliminates the lines (at least in my viewer).
I will add this fix to my script soon, because it is a simple fix.

combineAreas can be left to 'false' in your case.
Sorry about the runtime by the way, it really isn't much optimized for speed.

[kzhooou]

No worries on the speed it's good enough.

Small spikes appear when I did so

But I've found alternative way to make gaps less obvious using inkscape

Another small bug I experience is that the code does not always capture white filled areas, see below

Original_filledwhite.zip

highlighted are areas I fill white to cover the plot outside the boundary

[Conclusio]

Regarding the spikes: That's a shame, then the workaround needs improvement...
Regarding white filled areas: That's a Z-order problem. Use: epsclean(... , 'groupSoft',true); to handle that.

[kzhooou]

It works! Thanks again for your help!

[Conclusio]

You're welcome.

On last time, regarding the spikes again:
You can eliminate them with choosing this statement instead:
/f{GS 0.01 LW S GR fill}bd

So the value 1 is changed to 0.01. What this statement in general does is drawing an additional polyline with the given width (0.01) around every area, basically eliminating gaps between areas.

[kzhooou]

It works perfectly! Cheers!!

Brilliant! Editing that statement solved my problems too! Thank you!
