<h2>Introduction</h2> <p>VOLT is Microsoft’s tool for adding OpenType tables to fonts. It provides a graphical UI that enables a person to visualize what is going to happen with the substitutions and positioning lookups when they are created. VOLT also includes a proofing tool that permits the functionality of the font to be tested without having to install the font in the system.</p> <p>An explanation of VOLT menus and window layout are found in the article “<a href='/cms/scripts/page.php%3Fid%3Dvolt_ui%26site_id%3Dnrsi.html'>Microsoft VOLT UI Overview</a>”.</p> <p>Information on obtaining VOLT can be found <a href='http://www.microsoft.com/typography/VOLT.mspx' target='_blank'><img src='/cms/assets/icons/offsite_link.png'> here</a>.</p> <a name='07bc0f70'></a> <h2>Process of using VOLT</h2> <p>Before starting to add OpenType tables to a font it is important to understand what features will be used with which glyphs in the font. The glyph repertoire in the font will guide the implementation of OpenType tables for the font.</p> <p>The process of adding OpenType tables for VOLT is:</p> <ul class='dListUnordered'> <li>Set glyph properties.</li> <li>Create glyph groups.</li> <li>Create substitution lookups.</li> <li>Create positioning lookups.</li> <li>Create language, script, and feature tree.</li> <li>Test the features.</li> <li>Ship the font.</li> </ul> <a name='368fe771'></a> <h2>Tutorial</h2> <p>For the tutorial we will step through the process of using VOLT. Each step is a module in the tutorial. The SILDoulosUnicodeIPA font is used for this tutorial. The original font, before OpenType tables are added, is provided. There is a version of the font to compare your work with after each module is completed.</p> <p>Download here:</p> <table border='0' cellpadding='8' cellspacing='0'><tr><td align='left' valign='top'><img src='/cms/assets/icons/type-zip.gif' border='0' width='32' height='32' style='margin:1px 5px 0 0'></td><td align='left' valign='top'><small><b>VOLT Tutorial Font</b><br>Paul Nelson, 2001-09-02<br><a href='/cms/sites/nrsi/download/volt_tutorialfont.zip/VOLT_TutorialFont.zip'>Download "VOLT_TutorialFont.zip"</a>, ZIP archive, 487KB [26953 downloads] </small></td></tr></table><a name='7c032e95'></a> <h3>Step 1 – Set Glyph Properties</h3> <ul class='dListUnordered'> <li>Open the font you are going to work on. <ul class='dListUnordered'> <li>Start the VOLT program.</li> <li>Use the command <span class='menu_choice'>File / Open</span> to activate the <span class='menu_choice'>Open File</span> dialog. </li> <li>Navigate to the font you will work on and click on the <span class='GUI_button'> Open </span> button.</li> <li>Once the font has been one of the last four fonts you have worked on, you may select the font from the MRU (most recently used) font list found under the <span class='menu_choice'>File</span> menu selection.</li> </ul> </li> <li> Set font size preferences for the font. <ul class='dListUnordered'> <li>Use the command Tools-Options to open the Options dialog.</li> <li>Set the glyph size for use in grids.

If you see that the group the named “New Substitution” already selected and has a box around it, you can type the group name directly. Otherwise, you need to click on the <span class='menu_choice'>New Substitution</span> item to select the substitution lookup first.</li> <li>To edit the content of the substitution, select the substitution lookup to edit and 1) use the menu command <span class='menu_choice'>Tools / Edit Lookup</span>, or 2) click on the <span class='GUI_button'> Edit Lookup </span> button on the toolbar, or 3) double click on the substitution lookup you wish to edit.</li> <li>To delete a substitution, you need to select the substitution lookup that you want to delete and then use the command <span class='menu_choice'>Project / Remove Lookup</span> or click on the <span class='GUI_button'> Remove Lookup </span> button.</li> </ul> <p>The lookup type will be automatically assigned based on the lookups that are entered.</p> <p>Process Marks should be set to “ALL” if marks have an impact on shaping and to “NONE” if the marks should be ignored when doing substitutions. For example, the Arabic <span class='Em'>lam alef</span> ligature should be formed correctly even if there is a mark above the <span class='Em'>lam</span>.</p> <p>The Text Flow setting only impacts the display of the substitutions. All substitutions are entered in logical order.</p> <p>When making lookups for ligatures, you need to make sure you do the lookups for the larger lookups before the smaller ones. This is because the first match when searching through a lookup will terminate the search process. For example: “uni02E5 uni02E7 uni02E9 -> uni02E502E9“ must come before “uni02E5 uni02E7 -> uni02E502E7“ or you will never have the possibility of forming the uni02E502E9 from the combination of uni02E5 uni02E7 uni02E9.</p> <a name='8f3d1ed1'></a> <h4>Exercise 3a</h4> <p>Substitution Lookup – dotless [this lookup changes the dotted form to dottless form of the glyph if an AboveMark is placed

command <span class='menu_choice'>Project /Add Positioning</span> or click on the <span class='GUI_button'> Add Positioning </span> button (found in the bottom center of the main VOLT window).</li> <li>Edit the name of the positioning lookup. If you see that the group the named “New Positioning” already selected and has a box around it, you can type the group name directly. Otherwise, you need to click on the <span class='GUI_button'> New Positioning </span> item to select the positioning lookup first.</li> <li>To edit the content of the positioning, select the positioning lookup to edit and 1) use the menu command <span class='menu_choice'>Tools / Edit Lookup</span>, or 2) click on the <span class='GUI_button'> Edit Lookup </span> button on the toolbar, or 3) double click on the positioning lookup you wish to edit.</li> <li>To delete a positioning, you need to select the positioning lookup that you want to delete and then use the command <span class='menu_choice'>Project Remove Lookup</span> or click on the <span class='GUI_button'>  Remove Lookup </span> button.</li> </ul> </li> </ul> <p><span class='Runin'>Strategy for Anchor Attachments – </span>A letter may have several anchor attachment points, depending on how various classes of marks interact with the character. Anchor attachment points for the base glyph must have unique anchor names. </p> <p>The “Position First” column will contain a list of the base glyphs. The “Position Second” will contain a list of the marks that will be anchored to the base glyphs. </p> <p>To make the process of positioning marks on a glyph easier, it is best to put all members of a class of marks into a group. For this tutorial, this was done when the AboveMarks and BelowMarks groups were created. To use a group in VOLT, the name of the group is put between “<” and “>”, e.g. “<AboveMarks>”.</p> <p>All marks in the group should be adjusted first to allow for a single anchor on the base glyph to be used to correctly position the mark. After the mark is positioned, the mark should be locked in place.</p> <p>Once the marks have been locked into place it will be straight forward to concentrate on positioning the anchor points on the base glyph.</p> <a name='6fcf822a'></a> <h4>Exercise 4a</h4> <ul class='dListUnordered'> <li>Create a new positioning lookup and give it the name “Mark”.</li> <li>Set the positioning type to “Anchor Attachment” in the dropdown list.</li> <li>In the “Position First” column type in the list of base glyphs you will use. </li> </ul> <div class='Indent'><div class='Indent'><div class='dDataViewTable'>

You will need to uncheck this when you get ready to set the anchor points for the base glyph.</li> <li>Click on the mark and drag it to the location that will allow it to best be anchored to base glyphs. This will normally be centered above (<AboveMarks>) or below (<BelowMarks>) the “+”. Of course, the positioning depends on the behavior required for the language.

Make sure that you are not going to strip the working tables from your only working version of the font. That will require you to rebuild your font again. </li> </ul> <hr> <p><small>© 2003-2024 <a href='http://www.sil.org/' target='_blank'>SIL International</a>, all rights reserved, unless otherwise noted elsewhere on this page.<br> Provided by SIL's Writing Systems Technology team (formerly known as NRSI).
