Details:

The following script


figure (1)
imagesc (magic (4))
hold on
line ([1,1,4,4], [1,4,1,4])
hold off
print -dpng -r0 lineOnImage.png
print -dpdf -r0 lineOnImage.pdf


produces on screen a line with three segments over an image (see
lineOnImageScreenshot.png) as expected. When saving to PNG or PDF, the first
two segments are missing (see other attached files). This happens with all
graphics toolkits.

By taking apart the PDF in Inkscape, I found that the first two lines are
present, but hidden behind the image.

I am using Octave 4.2.1 from https://ftp.gnu.org/gnu/octave/windows/:
