we get scalable fonts with fields 7,8,12 at "0" like :
-bitstream-charter-medium-i-normal--0-0-75-75-p-0-iso8859-1
-dec-terminal-medium-r-normal--0-0-75-75-c-0-dec-dectech
but if we call :
XListFonts(serveur, "-*-*-*-*-*-*-0-*-*-*-*-*-*-*", 10000, &nbFonts);
we also get fonts with only field 7 at "0" like :
-bitstream-charter-bold-r-normal--0-120-100-100-p-0-iso8859-1
-adobe-new century schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
what about these fonts ?
Well, X Logical Font Description Conventions
Version 1.5
says (section 5):
"For a scalable font source, a scalable font name for each
character set is included in the list. In addition to
the scalable font name, specific derived instance names
may also be included in the list."
...
"Because some existing applications rely on seeing a collection
of point and pixel sizes, server vendors are strongly
encouraged in the near term to provide a mechanism for
including, for each scalable font name, a set of specific
derived instance names. For font sources that contain a set of
specific derived instance names."
So it is OK to have that in font list. It must be --0-0- base
name for every such font, and if it is not -- there is an error
somewhere in your X server or font server, and probably should be
fixed. If there are base entries -- then you don't need them.
But how to determine if a font is scalable or not when its fields 7, 8 and
12 are not at "0" ?
Why do you need it?
Usually you can safely assume, that this font is not scalable.
I don't really need it, existing choice is big enough !
But I only wanted to know the signification of "0" field in -adobe-new
century schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
I did these (easy to reproduce) tests with xfontsel and xlsfonts commands :
*xfontsel :*
- if we select a point size of 120, it's impossible to select a pixel
size of 0
- if we select a pixel size of 0, we only have the choice between * or 0
for point size
*xlsfonts :*
- xlsfonts -fn "-*-*-*-*-*-*-0-*-*-*-*-*-*-*" (pixel size of 0) : we can
see scalable fonts and fonts like -adobe-new century
schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
- xlsfonts -fn "-*-*-*-*-*-*-0-120-*-*-*-*-*-*" (pixel size of 0, point
size of 120) : we can see fonts like -adobe-new century
schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1
- xlsfonts -fn "-*-*-*-*-*-*-*-120-*-*-*-*-*-*" (point size of 120) :we
don't see anymore fonts like -adobe-new century
schoolbook-bold-r-normal--0-120-100-100-p-0-iso10646-1, which is
confusing because "-*-120-" also matches "-0-120-"
