--- Comment #12 from V Stuart Foote <vstuart.foote at utsa.edu> ---
@Aron, *

This really is NOT OUR BUG, and work on bug 67464 would be needed to do
anything else.

LibreOffice does not directly read EPS during filter import [1], insted it
requires one or more of 3 external helper programs.

Imagemagick or ghostscript -- both will produce BMP raster image, or will use
the empedded preview bitmap, usuually TIFF, of an epsi if present.

The third pstoedit will render EPS to vector, but will reomve verticies
resulting in visual distortion of the vector strokes. Windows builds of the app
have a "shareware' extension that will parse all verticies from the EPS in
generating an EMF vector graphic.

Both Imagemagick and pstoedit require a ghostsript installation be present.

These helpers are not managed by LibreOffice, they must be installed and
present on user profile PATH, if not so configured LibreOffice will not use the
helper.

If pstoedit is present on path it will render to EMF; otherwise the filter
picks the RenderAsBMPThroughGS (GS only no ImageMagick or pstoedit) or finally 
RenderAsBMPThroughConvert () (Imagemagick and GS on path).

The ieps routines remain in place and function when os/DE is correctly
configure. Removing regression and bibisect, function is dependent on os.

Please correct your os/DE to install the needed helper(s) and verify valid
PATH.

Please note, it really is more effective to use an external application to
directly convert EPS to EMF or SVG vector and then import that graphic. Also
that since its 7.0 release, command line use of ImageMagick's 'convert' helper
requires you install it's "legacy" module to have script access.

Needinfo is for OP and other reporters to retest with necessary "helpers"
configured as needed by LibreOffice.
