# SetFont

`SetFont family ?style? ?size?`

## Description

Sets the font used to print character strings. It is mandatory to call this procedure at least once before printing text or the resulting document would not be valid.
The font can be either a standard one or a font added via the AddFont procedure. Standard fonts use the Windows encoding cp1252 (Western Europe).
The procedure can be called before the first page is created and the font is kept from page to page.
If you just wish to change the current font size, it is simpler to call SetFontSize.
Note: the font definition files must be accessible. They are searched successively in:

- The directory defined by the `TCLFPDF_COREFONTPATH` constant (this constant is defined for default to the `font` directory located in the same directory as `tclfpdf.tcl`
- The directory `fonts` of the system

Example using `TCLFPDF_COREFONTPATH`:

    set TCLFPDF_COREFONTPATH  "c:\my fonts";

If the file corresponding to the requested font is not found, the error "Could not include font definition file" is raised.

## Parameters

`family`
  Family font. It can be either a name defined by AddFont or one of the standard families (case insensitive):
  - `Courier` (fixed-width)
  - `Helvetica` or `Arial` (synonymous; sans serif)
  - `Times` (serif)
  - `Symbol` (symbolic)
  - `ZapfDingbats` (symbolic)
  It is also possible to pass an empty string. In that case, the current family is kept.
`style`
  Font style. Possible values are (case insensitive):
  - empty string: regular
  - `B`: bold
  - `I`: italic
  - `U`: underline
  or any combination. The default value is regular. Bold and italic styles do not apply to `Symbol` and `ZapfDingbats`.
`size`
  Font size in points.
  The default value is the current size. If no size has been specified since the beginning of the document, the value taken is 12.
