OpenType Designer

Previous  Next

The OpenType Designer provides you with an easy to use visual way to edit glyph positionings. In the left pane you see the how the features and lookups are organized in your font, and depending on the lookup type you can edit the properties in the right pane.

The splitter on the dialogue can be dragged to adjust the width of the panes. Double-click the thumb bar (¦) to dock or the script pane when it is not needed or to undock it.

The left toolbar allows you to add, remove, move, rename and change scripts, languages, features and lookups. Most of these functions are also available in the right-click menu when you have selected an item.

Add

Add a new script, language, feature or lookup. The available options depend on which item is selected in the tree. If, for example, you select a feature, the current script and language will already be pre-determined on the add dialog.

Delete

Deletes a script, language, feature and/or lookup. A popup window will ask you to confirm and select how you want to delete the selected item.

Rename

Rename the selected item. Please note that each script, language, feature or lookup name has to be unique.

Change tag

Allows you to change the tag (type) of scripts, languages and features. Please note that each tag may only exist once on the same level of the tree.

Move up

*) Move a lookup or feature up

Move down

*) Move a lookup or feature down

Autoname

This will provide all your scripts, languages, features and lookups with consistent and if possible meaningful names

Autokern

This will automatically create kerning pairs for pair adjustment lookups. See also Autokern.

Autogroup

Only affects Single and Pair Adjustment lookups: Will group pairs and single adjustments together based on their left and right side bearing, width and current adjustment value. This will greatly reduce the number of visible kerningpairs and allow you to quickly change adjustment values of multiple glyphs at once.

Break groups

Only affects Single and Pair Adjustment lookups: Will break all groups into separate kerning pairs or single adjustments.

Cleanup

Permanently deletes all unused lookups and features, you can use this to quickly clean up your lookups and features.

*) The order in which feature and lookups are defined is also the order in which they are processed by host applications. This button allows you to move a feature or lookup down so they are processed earlier or later. As soon as the host application has found a match in one of the lookups it will stop processing. This can be useful to create an "override" for kerning pairs for example. Consider a large kern lookup which contains several group-based pairs. If one or two pairs need extra modification, you can add another lookup to the feature and add the "exceptions" before the actual kern table. This way the host application will find the "exception" first and will skip the "wrong" value from the large lookup.

 

The right-click menu on the left pane also provides some additional lookup specific actions:

Export

Only available for Single and Pair Adjustment lookups: Allows you to export only a single lookup table (including all used groups) and import it into another font

Break groups


Auto group

Perform auto grouping on the selected lookup table only

 

Import

The import function allows you to import an OpenType Layout Feature Definition script. If the script contains only a lookup table, the lookup table will be added to the existing lookups. If the script contains script and language declarations, all existing items will be deleted and overwritten.

 

Export

The export function allows the export of all scripts, languages, features and lookup definitions, including those that are not in use. Group definitions will also be exported. If you want to export only a single lookup table, you can right-click on one of the lookup tables, and select “Export Lookup”. Please note that exporting a single lookup is only supported for Single and Pair adjustments.

 

Lookupflags

Right to Left

Used to indicate that the lookup is used for Right to Left writing. For kerning pairs this means that the first and second glyph will be visually swapped.

Ignore Base Glyphs

If checked, the processing application will skip over the base glyphs

Ignore Ligatures

If checked, the processing application will skip over ligatures

Ignore Marks

If checked, the processing application will skip over all combining marks



Clear subtable will delete all entries of the currently selected subtable, to clear an entire lookup table (including all subtables) use the right-click menu in the left pane.

 
Settings

The settings button will open the Designer Settings
