convenient wizards.

! Edit individual font characters using tools to manipulate each character bitmap.
! Apply transformations to one, all, or a sequence of font characters to embolden,

italicize, underline, and apply other transformations.

! Display and change character or font properties such as kerning, baseline offset, and

orientation.

! Convert character sets to AFP format and AFP format fonts to other supported

formats.

DesignPro Font Editor fully supports character set editing and conversion to and from
AFP bounded-box and unbounded-box fonts. It also supports opening, editing, and saving
double-byte fonts.

Working together with DesignPro Manag er and Converter, you can import and convert
fonts to the Elixir generic format, perform desired edits, and then reconvert to original or
other formats.

DesignPro Font Editor Overview

DesignPro Font Editor is a bitmap character set editor that provides tools for creating and
editing fonts. The Font Editor enables you to work in a what-you-see-is-what-you-get
(WYSIWYG) environment.

With the DesignPro Font Editor you can:

! Create new raster fonts using an existing vector fonts, or from scratch
! Edit, transform or delete characters in a character set
! Merge characters from one character set into another
! Edit a single character spacing or placement
! Edit character cells width or height
! Manage images saved as fonts
! Convert fonts to different formats.

15

What is in the Workspace?

The Font Editor workspace comprises the following main components:

! Character set window
! Toolbox
! Messages window

You can customize the position and size of the windows to meet your requirements. The
workspace windows can be, displayed as either floating, docked, or can also be hidden
from view. The following sections explain each window in detail.

Font Editor components.

16 DesignPro Font Editor for AFP User Guide

Character Set Window

The character set window displays immediately below the toolbar and contains the active
character set. The character set window is vertically scrollable only. You use the character
set window to create, edit and save character sets.

Double clicking a character in the character set window enables you to edit the selected
character. In edit mode, the character set window is split into three panes:

! Character set pane displays at the bottom of the screen.
! Editing pane shows the selected character in magnified view for editing.
! The right most pane displays the selected character in its original size. Magnifying or

reducing the view displays a locator box over the character allowing panning of the
character. Panning is a display method for scanning the selected character
horizontally or vertically. You can click and drag the locator box to bring an off­screen extension of the selected character smoothly into view in the editing pane.

Character set window split into three panes in edit mode.

Toolbox

Toolbox is displayed at the left of the design area by default. The Toolbox displays
different options available for most toolbar items in the Drawing toolbar and the

Transform toolbar. Clicking on the toolbar item displays the associated options in the
Toolbox. The last selected toolbar item options are not changed in the Toolbox until

another toolbar item (whose options are available) is selected.

Chapter 2: Font Editor Environment 17

Messages Window

The Messages window is docked at the bottom of the workspace by default and can be
docked to any other position as required. This window displays processing and
compilation errors, warnings and informational messages as generated by the application.

You can clear messages in this window by pressing <Ctrl > + <D> on the keyboard. You
can also close the Messages window by selecting View>Messages or by clicking at

the top of the Messages window or by pressing <Ctrl> + <Shift> + <M> on the keyboard.
Closing the Messages window provides more space within which you can work; however,
this window automatically redisplays whenever a message is generated by the application.

You can change the message display settings by right-clicking in the Messages
window and choosing the required options. You can also change the Messages
window defaults using the Options dialog Messages category.

Using Workspace Tools

DesignPro Font Editor provides toolbars for easy access to the most commonly used
application commands. You can perform standard MS-Windows operations to hide or
display a toolbar, or dock a toolbar at the edge of the workspace. For detailed information
on customizing the workspace tools, see "Customizing Toolbars and Menus" on page 67
in Chapter 5: "Customizing DesignPro Font Editor".

Menu bar and Toolbars

A menu bar with drop-down menus displays directly below the application title bar by
default. These drop-down menus provide both standard MS-Windows and application­specific options. Selecting a menu item performs the associated action or displays a
submenu or a dialog.

Directly below the menu bar are toolbars with buttons that provide access to the most
commonly used commands and tools. You can hide or display all available toolbars by
selecting View>Toolbars>toolbar name from the menu bar. The toolbar items provide
access to the frequently used menu bar commands.

Status Bar

The status bar displays, by default, along the lower edge of the DesignPro Font Editor
workspace. The status bar displays a tooltip when the mouse pointer is placed over a
command.

18 DesignPro Font Editor for AFP User Guide

When you move the mouse pointer over a character, the status bar displays the Character
Id in decimal and in hexa-decimal format, character width in pels, and character type such
as blank, non-blank or spacing.

Type spacing specifies a blank bitmap used to provide space between
characters or words. All other characters containing bitmaps are non-blank
characters.

Status bar showing the tooltip, selected character width and type, and the character id.

In edit mode, the status bar displays additional information about the character; column
and row locations, zoom magnification and reduction sizes, and horizontal and vertical
coordinates. The coordinates help you in drawing objects within the editing pane.

Status bar in the edit mode.

Chapter 2: Font Editor Environment 19

Grid

You can activate the grid by clicking on the View toolbar or by selecting View>Grid
from the menu bar. The grid feature allows you to position and align objects accurately in
the character set window. In Font Editor the grid can be activated when the zoom is set 3X
(three times) the object size or greater in the edit mode only.

You can also use <F4> shortcut key to enable or disable the grid.

Ruler

You can activate the ruler by clicking on the Drawing toolbar. The ruler feature helps
you in accurately editing an object in the character set window . This feature is available in
the edit mode only. It is used to measure the distance between two points. The distance is
shown as line length in the status bar.

The difference between the two points is dis played in the status bar.

20 DesignPro Font Editor for AFP User Guide

Navigating the Workspace

Workspace components are organized in various parts of the window according to
purpose. You can navigate to the workspace components and choose a command as
follows:

! To use a menu bar:

Click the appropriate menu, and then select the required o ption from drop-down list.

! To show a toolbar:

From the View menu, select Toolbars > toolbar name. A check mark next to the
required toolbar indicates selection.

Choosing Commands

A command instructs DesignPro Font Editor to perform a specific action. Y ou can choose
a command by either:

! Clicking a toolbar button
! Selecting a menu command
! Using a shortcut menu
! Using a shortcut key

In the chapters that follow, command selection is described using the most common
method for the described task. However, related command selections can be used to
accomplish the same instruction and are listed down in notes.

Undoing and Repeating Commands

Font Editor keeps track of your editing and formatting changes. If you want to undo a
change or command selection, you can usually reverse several previous actions.

Redo command is available in the main view only. You can repeat the last reversed action
using the redoing command. It is not activated in the edit mode.

You can update the changes made to the font by clicking Update changes on the Standard
toolbar. This command is enabled in the edit mode only. Updating the changes disables
the undo command.

Chapter 2: Font Editor Environment 21

Use <Ctrl> + <Z> and <Ctrl> + <Y> shortcut keys to perform the undo and
redo actions respectively.

Font Structure

In this chapter...

! AFP Font Types

! AFP Font Components

! AFP Font Naming Conventions

! Elixir Legacy Font Structure

! Elixir Font Converted from a Non-AFP Source

! Elixir Font Converted from an AFP Source

This chapter describes font structures and how DesignPro Font Editor handles fonts
originating from AFP and non-AFP sources. For detailed information on AFP fonts, refer
to IBM's Font Object Content Architecture Reference (S544-3285-05) manual.

Font Structure

A font is a set of graphic characters of a given typeface and other properties, such as size,
pitch, and style. There can be up to 256 characters in a font (for AFP fonts, you can have a
character set with more than 256 characters), consisting of numerals, letters, punctuation
marks, and symbols.

Each typeface (Times New Roman, Arial, etc.) can have many fonts. Each font has a
specific set of properties defining all of the above characteristics. Most Windows
applications blur this definition by allowing you to choose a typeface and then set the
other options that define a specific font.

DesignPro Font Editor uses a proprietary structure that enables you to display and edit
characters in a WYSIWYG format. In addition, you can also convert TrueType and ATM
font formats to Elixir format fonts.

DesignPro Manager converters allow you to convert AFP Bounded Box and Unbounded
Box fonts to Elixir format fonts.

23

The following sections describe components of a font type family, a term that
encompasses all characteristics of printed text.

Type Family

A type family is a group of typefaces that have a common basic design, but may vary in
size and style. Examples of type family are:

! Sonoran Sans Serif
! Courier
! ITC Avant Garde Gothic

Ty p e f a c e

A typeface is a collection of characters having the same style, weight, and width, as
described below:

! Style is the inclination of characters with respect to the vertical axis (e.g., Roman

[upright] or italic [top slant to the right]).

! Weight is the degree of boldness of a typeface (e.g., semi-light, light, medium or

bold).

! Width is the degree of horizontal spacing of a character (e.g., condensed or normal).

Typeface examples include:

! Sonoran Sans Serif Roman medium normal
! Helvetica italic bold condensed
! Times italic light nor mal .

Type Font

A type font (also called a font) is a collection of characters that share the same type family,
typeface and size. Font examples include:

! Sonoran Sans Serif 10-point Roman medium normal
! Helvetica 8-point italic bold condensed
! Times 12-point italic light normal

24 DesignPro Font Editor for AFP User Guide

AFP Font Components

Each AFP font has three components:

! Character set
! Code page
! Coded font

Character Set

A character set consists of a finite set of characters. The character set corresponds to the
type font (or font) described in
type family, typeface, bitmap, and point size, and can also include information about the
baseline positioning, rotation, ascenders, descenders, etc. Each character within the
character set is assigned a unique identifier called a graphic character ID (GCID), or
Graphic Character ID.

Code Page

A code page provides a map for the AFP printer to find the correct character for printing in
a selected character set. A code page contains hexadecimal identifiers for graphic
characters within a character set (each key on a keyboard corresponds to a hexadecimal
code point identifier). Arrays of code points representing characters establish a numeral
order of these characters. Each code point, or point on the code page, has a GCID which
corresponds to the GCID in the character set. When printing on an AFP printer, the code
point is matched to a GCID in the code page. This allows you to use different code pages.
For example, to print subsets of characters in a character set (like for different European
languages).

Font Structure

. A character set contains information about a single

Code page displaying the hexadecimal code point identifiers along with the
corresponding graphics character Ids.

Chapter 3: Font Structure 25

Coded Font

A coded font is a font file that associates (links) the character set with the code page. In
order for a character to be printed, you must include it in the character set, and list it in a
code page, and the two must link in a coded font.

AFP Font Components.

For example, the binary representation of upper case A on a host keyboard is 11000001 or
hexadecimal C1 (also called the code point). When printing the letter A:

! Corresponding code point (C1) is matched to a GCID in the code page for the font

(LA020000 as shown in the code page figure above).

! GCID is matched to a raster pattern in the character set for the font.
! Raster pattern is printed as upper case A.

Note that you must include all GCIDs (in the code page) in the character set, otherwise an
error condition will exist at print time.

AFP Font Types

AFP fonts can be either Bounded Box or Unbounded Box. .

Bounded Box Fonts

Bounded Box fonts are AFP fonts for IBM printers other than 3800. For printing rotated
fonts on these printers, only one font version is required, all rotations are included in one
font.

26 DesignPro Font Editor for AFP User Guide

Unbounded Box Fonts

Unbounded Box fonts are AFP fonts for IBM 3800 printers. A characteristic of
Unbounded Box fonts is that for printing rotated text, a separate font is required for each

of the four rotations (i.e. 0

o

, 90o, 180o, and 270o from inline print direction).

AFP Font Naming Conventions

AFP font naming conventions relate the inline (print) direction and character rotation
combination, to a two-character file name prefix. AFP font names are limited to eight
characters. The two-character prefix identifies the coded font or character set, and the
remaining (one to six) characters are the coded font ID or character set ID (refer to Font
Object Content Architecture Reference (S544-3285-05) manual for more information). In
order to track and manage fonts, it is recommended that you use a font naming
convention.

Bounded Box Naming Convention

All Bounded Box coded fonts are prefixed with X0, and all Bounded Box character sets
are prefixed with C0.

Unbounded Box Naming Convention

Unbounded Box font file name prefixes depend on inline (print) direction and font
rotation, as shown in the following table:

Font Characteristics

This section describes some font characteristics, particularly their appearance on a printed
page.

Character Placement

Characters are placed on the printed page using the following concepts. For more
information on these concepts, refer to the tasks immediately after this section.

Bounded-Box

Bounded Box characters are placed using the following:

! Character reference point
! Character A-space
! A-space

28 DesignPro Font Editor for AFP User Guide

! Character baseline offset
! Uniform baseline offset
! Character increment
! Uniform increment
! Raster-pattern box

Unbounded-Box

Unbounded Box characters are placed using the following:

! Character reference point
! Uniform inline offset
! Uniform baseline offset
! Character increment
! Uniform increment
! Raster-pattern box.

Inline (Print) Direction

The inline print direction (or simply print direction) is the direction in which characters
are added to a line of text. The inline print direction has four possible values: 0o, 90o,

o

180

, or 270o.

Limitation - Unbounded Box fonts do not support 180o print directions.

Character Baseline

The character baseline is a reference to which characters align as they are added to the
page in the inline (print) direction. The character baseline is always parallel to the inline
(print) direction.

Chapter 3: Font Structure 29

Character baseline.

Character Rotation

Character rotation are the angles through which a printed character is rotated clockwise in

o

90

increments about the character baseline. The following figure shows the four character

o

rotations for the 0

Character rotations for inline print direction.

inline (print) direction:

As there are four inline print directions, there are a total of 16 combinations of inline
(print) directions and character rotations. Since Unbounded Box fonts do not support the

o

180

print directions, only 12 combinations apply for Unbounded Box fonts.
