Do you have a xpm->eps converter defined? I don't remember why I defined
that, but that is not the point. My point was that I would expect the
shortest route to be chosen.
Here is the output of lyx -dbg graphics for the case I mentioned:
Attempting to convert image file: ~/lyxdocs/these/images/chap1_neurone.png
with recognised extension: png.
Scanstring: PNG
Recognised Fileformat: png
Scanstring: PNG
Recognised Fileformat: png
The file contains png format data.
The image loader can load the following directly:
Windows/OS2 BMP file, extension "bmp"
NASA/NOST FITS, extension "fits"
CompuServ GIF, extension "gif"
JPEG/JFIF format, extension "jpg"
Portable Pixmap, extension "ppm"
Portable Graymap, extension "pgm"
Portable Bitmap, extension "pbm"
PostScript, extension "ps"
SGI Iris, extension "sgi"
Tag Image File Format, extension "tif"
X11 Bitmap, extension "xbm"
X Window Dump, extension "xwd"
XPM format, extension "xpm"
Of these, LyX recognises the following formats:
gif, jpg, ps, xpm
Converting it to ps format.
