Describe the bug

A clear and concise description of what the bug is.

I cannot find the linetype option in contour plot attributes any more. Is this removed intentionally?

This is Linux x86_64 version.

Thanks!

I believe @sambo57u is referring to the line style option. I verified that it is missing in 3.0 and present in 2.13.3.

It was removed on purpose, due to upgrade to VTK-8 and no longer having support for line-stippling.

[brugger1]

Line-stippling support was removed from VTK when they rewrote the OpenGL rendering. It has been several years since that work was performed and they never implemented it, so I can't image that they will ever implement it.

[sambo57u]

This is a bad because many journals ask us to have identifiable contours in black and white for the published version of the paper. Only option is to put numbers on each individual contour since a legend wan't help either.

I went for a quick look on Google for any tool that could take color line drawings and convert them to black-and-white patterned lines (dots, dot-dash, dash-dash-dot, etc.). I didn't get what I was expecting. But, I've got to believe this is a solved problem with some tools out there in either Gimp, ImageMagick or Photoshop. Its non-ideal of course but might be best option.

[sambo57u]

It is a shame. I usually do edits on pdf using libreoffice draw with pdfimport (the best solution) or inkscape. But not having contour line type is a major drawback, just saying!

[markcmiller86]

Maybe this ref might offer a new approach to take in VisIt.

This is a very important feature that I have used many times. Hope it will come back in future.

removed reviewed b/c another user ask about this, not sure we will have any new ideas but we can discuss.
