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. </pre> </blockquote> <pre class="moz-quote-pre" wrap="">But how to determine if a font is scalable or not when its fields 7, 8 and 12 are not at "0" ? </pre> </blockquote> <pre class="moz-quote-pre" wrap=""> Why do you need it?

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-" <blockquote type="cite" cite="mid:20190304171806.ks72tmir734pk2d4@azor.tzirechnoy.ru"> <pre class="moz-quote-pre" wrap=""> _______________________________________________ <a class="moz-txt-link-abbreviated" href="mailto:xorg@lists.x.org">xorg@lists.x.org</a>: X.Org support Archives: <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/archives/xorg">http://lists.freedesktop.org/archives/xorg</a> Info: <a class="moz-txt-link-freetext" href="https://lists.x.org/mailman/listinfo/xorg">https://lists.x.org/mailman/listinfo/xorg</a> Your subscription address: %(user_address)s</pre> </blockquote> </body> </html>
