Jagged outline using Matlab 2014b

Question

I am plotting some maps using Matlab that use mapshow to plot the country border from a shapefile. I then export them to both a PDF and EPS format using the

Answer 1

Matlab acknowledged that this is known bug. For me the first fix worked.

The issue of jagged lines on the figures while exporting in the vector format is a known bug in MATLAB R2014b. It is associated with the combination of linejoins and meterlimits used in vector format.

To work around this issue, use the attached function fixeps to post process the EPS file. You can use one of the following ways to call this fixeps function.

fixeps('input.eps','output.eps','LJ') % Will change the linejoins to round

fixeps('input.eps','output.eps','ML') % Will correct the miterlimit

function fixeps(inname,outname,fixmode)
if nargin==2
    fixmode = 'LJ';
end
fi = fopen(inname,'r');
fo = fopen(outname,'w');
tline = fgets(fi);
while ischar(tline)
    if (strcmp(tline,['10.0 ML' 10])) % Replace 10.0 miterlimit
        switch (fixmode)
            case 'LJ'
                fwrite(fo,['1 LJ' 10]); % With round linejoin
            case 'ML'
                fwrite(fo,['2.5 ML' 10]); % With smaller miterlimit
        end
    else
        fwrite(fo,tline);
    end
    tline = fgets(fi);
end
fclose(fo);
fclose(fi);
