Just an oddity. you are right, the problem is the function which searches for a loaddable format - snip - Of these, LyX recognises the following formats: bmp, ppm, ps, tiff, xbm, xpm - snip - these are sorted, so ps is found before xpm. should be done in a better way.

Thank you for the info, though. Are there chances to get working rendering of ps, eps or pdf back? A question concerning xforms development, I guess? Not having to convert these would be nice. My original message was a somewhat academic question about lyx converting png->xpm->eps->ps, even though xpm can be loaded directly. Why the detour? This is not _really_ relevant, since I think the xpm->eps converter was not there by default, and I don't remember why I put it there. If you leave that out, there is only one route, png->xpm, which gets loaded correctly. Just an oddity. Jan

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.

Viewing images in lyx-1.2: Choice of the converter to use
By default a converter PNG->EPS is defined. Since I defined an EPS->PS converter, Lyx then converted PNG->EPS->PS and failed to load the image (see previous message). So I removed the PNG->EPS converter, so that the PNG->XPM get used. However, the images still didn't get loaded. "lyx -dbg graphics" shows that lyx converts PNG->XPM->EPS->PS! Lyx _can_ load xpm directly and does so, if I delete the EPS->PS converter. This is minor once one knows what happens. There are always ways to work around this, defining only the right converters. But it still seems odd. Jan PS : This has been verified using lyx1.2.1cvs as of june 22 on Solaris(sparc) 2.7, xforms 0.89.6 and Image Magick 5.4.5.
