Hello,
My system : Linux Debian 10
fontconfig version : 2.13.1
I have this small code:
#include <stdio.h>
#include <stdlib.h>
#include <X11/Xft/Xft.h>
#include <Xlib.h>
#include <fontconfig.h>
int main(void) {
Display * display;
int screen;
XftFont * font;
const char * newFont="Liberation Sans:style=Bold Italic";
FcValue fcValue;
display=XOpenDisplay(NULL);
screen = DefaultScreen (display);
font=XftFontOpenName(display,screen,newFont);
FcPatternGet(font->pattern,FC_FAMILY,0,&fcValue);
printf("font family : %s\n",(char *)(fcValue.u.s));
FcPatternGet(font->pattern,FC_WEIGHT,0,&fcValue);
printf("font weight : %d\n",fcValue.u.i);
FcPatternGet(font->pattern,FC_SLANT,0,&fcValue);
printf("font slant : %d\n",fcValue.u.i);
}
I compile it with command:
gcc -g -Wall -I/usr/include/X11 -I/usr/include/X11/Xft
-I/usr/include/freetype2 -I/usr/include/fontconfig test.cc -o test -lX11
-lXft -lfontconfig
If I execute ./test , I get :
font family : Liberation Sans
font weight : 0
font slant : 100
font family and font slant are well displayed, but font weight is always
to '0' (thin) , whatever weight I choose for 'newFont'.
Additional infos:
--- font "Liberation Sans:style=Bold Italic" is installed - command:
fc-match "Liberation Sans:style=Bold Italic" gives:
LiberationSans-BoldItalic.ttf: "Liberation Sans" "Bold Italic"
--- problem doesn't occur under Linux Ubuntu 18.04 with same version of
fontconfig
