Addition of a new standardized font

Hi

In general I think that the Eagle approach to limit the number of

available fonts is a good one since it makes it much easier to get a

consistent appearance of the symbols in the libraries. However I think

that the collection of fonts is too limited at the moment.

 

I think that a logical step in the development of Eagle would be to

include a new standardized font, such as the osifont

(http://code.google.com/p/osifont/). Schematics designed with this font

will be accepted by customers requiring the use of fonts according to

ISO3098, for instance by requiring fulfilment of IEC61082.

 

Besides that technicality, osifont is free and it is designed to be

readable.

I think thas is a good idea, and a good choice of font.

I fully agree with this (both).

This request is very long-standing, BTW... (Previously, Hershey fonts

have been suggested, which is quite similar.)

When implementing new fonts, one should always consider WHAT these fonts

should be used for:

  1. The suggested TrueType font is very useful for SCHEMATICS,

     because it's both readable and technical.

  2. For BOARDS, however, a font is needed that can easily be

     sent to a whole range of sophisticated output devices, like

     'normal' printers, HPGL plotters, Postscript files, Gerber

     devices, etc. This can NOT be properly done with such

     TrueType fonts.

  3. The same is valid for the TrueType (or other outlined

     font) technology in general: Depending on the operating

     system and its current font engine implementation, the

     actual rendering of text will be DIFFERENT in size,

     leading, width, etc. The differences here are so small that

     they should not matter too much in the schematics, but on

     board they might be the reason why copper pour changes,

     so that unconnected islands appear or other stuff like that.

  4. In order to have the board behave COMPLETELY reliable,

     so-called VECTOR fonts (or stroked fonts) need to be used,

     which is why I proposed the Hershey stuff long time ago.

Therefore: The TrueType font IS nice, but just cannot be used for the

board. A better STROKED font is needed for that.

The suggested font appears exactly like the previously suggested (by

you, as well as by me) hershey font. I don't know how/if this font can

be "vectorized" as well, but it's pretty clear and obvious that a new

font must indeed be stroked, i.e. drawn with lines (of constant width).

I don't mind if it's hershey, ISO or something else - it simply has to

look like these two.

The Hershey fonts are vector.  However, instead of Cadsoft picking and

imposing fonts on us, they should publish a font file format and allow us

to tell Eagle what font to use.  Converting the Hershey fonts, or any other

vector fonts, to whatever format Cadsoft decides should be easy.

Along with that they should allow some way of specifying arbitrary

character codes in the text command so that we can access non-ASCII

characters at unused character codes of our chosing.  My graphics programs

generally use vector fonts, and I have added non-ASCII symbols I

occasionally use for some of the unused character codes 0-31.  For example,

the upper case omega is code 7 and lower case micron code 3.  I don't

expect, nor want, Cadsoft to provide anything more than the standard

character set.  As long as we can define our own fonts, that's no problem.

I'd probably write a program to convert my modified Hershey simplex.h font

to Cadsoft's format and not look back.
