 link:/commands/references/ashow/[`ashow`] paints the characters of `string` in a manner similar to link:/commands/references/show/[`show`]. But while doing so, link:/commands/references/ashow/[`ashow`] adjusts the width of each character shown by adding `ax` to the character's x width and `ay` to its y width, thus modifying the spacing between characters.

 === Description
 
 link:/commands/references/charpath/[`charpath`] obtains the character path outlines that would result if `string` were shown at the current point using link:/commands/references/show/[`show`]. Instead of painting the path, however, link:/commands/references/charpath/[`charpath`] appends the path to the current path. This yields a result suitable for general filling, stroking, or clipping.

 link:/commands/references/currentfont/[`currentfont`] returns the current font dictionary in the graphics state. Normally, this is the font most recently established by link:/commands/references/setfont/[`setfont`] or `selectfont`.

+=== PostScript Level

+*Level 1* and later

 === Description
 
 link:/commands/references/definefont/[`definefont`] registers `font` as a font dictionary associated with `key` (usually a name). link:/commands/references/definefont/[`definefont`] first checks that `font` is a well-formed font dictionary—in other words, contains all required key-value pairs. It inserts an additional entry whose key is `FID` and whose value is an object of type `fontID`. The dictionary must be large enough to accommodate this additional entry. It makes the dictionary's access read-only. Finally, it associates `key` with `font` in the font directory.

 link:/commands/references/findfont/[`findfont`] obtains a font dictionary identified by the specified `key` and pushes it on the operand stack. The `key` may be a key previously passed to link:/commands/references/definefont/[`definefont`], in which case the font dictionary associated with `key` (in the font directory) is returned.

 === Description
 
 link:/commands/references/makefont/[`makefont`] applies `matrix` to `font`, producing a new `font'` whose characters are transformed by `matrix` when they are shown. link:/commands/references/makefont/[`makefont`] first creates a copy of `font`. Then it replaces the new font's `FontMatrix` entry with the result of concatenating the existing `FontMatrix` with `matrix`. It inserts two additional entries, `OrigFont` and `ScaleMatrix`, whose purpose is internal to the implementation. Finally, it returns the result as `font'`.

 link:/commands/references/setfont/[`setfont`] establishes the font dictionary parameter in the graphics state. This specifies the font to be used by subsequent character operators, such as link:/commands/references/show/[`show`] and link:/commands/references/stringwidth/[`stringwidth`]. The `font` must be a valid font dictionary previously returned by link:/commands/references/findfont/[`findfont`], link:/commands/references/scalefont/[`scalefont`], or link:/commands/references/makefont/[`makefont`].

 link:/commands/references/stringwidth/[`stringwidth`] calculates the change in the current point that would occur if `string` were given as the operand to link:/commands/references/show/[`show`] with the current font. `wx` and `wy` are computed by adding together the width vectors of all the individual characters in `string` and converting the result to user space.
