fontforge EnvironmentError: Could not load image file

Question

I am trying to create font from single SVG files. Here the sample:

#!/usr/local/bin/fontforge
# file test.py

import fontforge;

font=fontforge.font();
glyph = font.createChar(65);
glyph.importOutlines("/home/user/guitar.svg");
# or glyph.importOutlines("~/guitar.svg");
# or glyph.importOutlines("./guitar.svg");
# or glyph.importOutlines("guitar.svg");

Any attempts to load single SVG file cause the same error:

Traceback (most recent call last):
    File "test.py", line 8, in <module>
    glyph.importOutlines("/home/user/guitar.svg");

Where am I wrong?

Environment:

file rights

ls -la /home/user/guitar.svg -rwxrwxrwx 1 user user 3728 Jun 30 20:46 guitar.svg

OS

$ uname -a Linux servername 2.6.32-431.11.2.el6.i686 #1 SMP Tue Mar 25 17:17:46 UTC 2014 i686 i686 i386 GNU/Linux

$ cat /etc/centos-release CentOS release 6.5 (Final)

Python version

$ python --version Python 2.7.7

Fontforge version

P.S. The same test is OK at Ubuntu 12.04 but the fontforge is other version

Got same problem.

Inside fontforge source file Python.c the code for loading image is

    GImage *image = GImageRead(locfilename);
    int ly = ((PyFF_Glyph *) self)->layer;
    if ( image==NULL ) {
        PyErr_Format(PyExc_EnvironmentError, "Could not load image file %s", locfilename );
return(NULL);
    }

And then there is a bug in switch for SVG, just look inside GImageReader.c and try to find SVG :)

GImage *GImageRead(char * filename) {
    char *pt;

    if ( filename==NULL )
return( NULL );

    pt = strrchr(filename,'.');
    if ( pt==NULL )
    pt = "";
    if ( strmatch(pt,".bmp")==0 )
return( GImageReadBmp(filename));
    else if ( strmatch(pt,".xbm")==0 )
return( GImageReadXbm(filename));
    else if ( strmatch(pt,".xpm")==0 )
return( GImageReadXpm(filename));
#ifndef _NO_LIBTIFF
    else if ( strmatch(pt,".tiff")==0 || strmatch(pt,".tif")==0 )
return( GImageReadTiff(filename));
#endif
#ifndef _NO_LIBJPEG
    else if ( strmatch(pt,".jpeg")==0 || strmatch(pt,".jpg")==0 )
return( GImageReadJpeg(filename));
#endif
#ifndef _NO_LIBPNG
    else if ( strmatch(pt,".png")==0 )
return( GImageReadPng(filename));
#endif
#ifndef _NO_LIBUNGIF
    else if ( strmatch(pt,".gif")==0 )
return( GImageReadGif(filename));
#endif
    else if ( strmatch(pt,".ras")==0 )
return( GImageReadRas(filename));       /* Sun raster */
    else if ( strmatch(pt,".rgb")==0 )
return( GImageReadRgb(filename));       /* SGI format */

return( NULL );
}

Yes, I also checked the sources, but did not dare to change even a single line ;) So I changed the server, reinstall and upgraded fontforge — pvolyntsev, Aug 15 '14 at 06:40
