PNG output shows unwanted lines in PDF output (Overleaf)
0
I'm writing a document in Overleaf.
When I save the document to a PDF, images that look like this on my desktop and editor:
come out looking like this:
One solution:
Open each of these corrupted images in adobe illustrator, make any arbitrary change, and save the document. Viola. The lines disappear. But, I have many corrupted images, and this is a time-consuming solution.
I suspect...
that the issue is with overleaf's compilation engine. I've tried changing it between pdfLaTex, LaTeX, XeLaTeX, and LuaLaTeX and it makes no difference.
Any ideas?

This looks like an issue of the pdf viewer which has difficulties with the transition between transparent and white backgrounds. Try another pdf viewer.

Stupid question: if you have the image in adobe illustrator, this sounds like they would be vector graphics. Why do you save them as png and not as e.g. pdf?

Is there any way you could help someone here to reproduce the problem?

samcarter : excellent point. I tryed another PDF viewer and found the same issue--but it can't be ruled out. And you're spot on that it's a transparent background, white background issue. @henry, here's a link to one of a file with a combo of transparent and white backgrounds (goo.gl/xUtN5d). As samcarter pointed out, you may not be able to reproduce the issue on Overleaf since this may be a PDF viewer problem. I suspect that exporting the image as PDF to begin with, or as PNG with white background instead of transparent might fix the issue. I'll report back for others with this issue.

There is a significant issue in the way colours have been saved that stops me from suggesting a solution based on Irfanview. The best result is to open in MSpaint and resave However paint is not easily scripted. So I suggest image magix using a command such as convert img1.png -background white -flatten img1-white.png (which oddly was the non working command in this question) stackoverflow.com/questions/2322750/… Seems to be the best option for looping through a set of your files
