ViewISO 1.1 - TrueType font viewer

ViewISO is a program designed for viewing ISO-8859 charsets using TrueType
Unicode fonts. It can be useful to check if a TrueType font contains glyphs for
given charset. On the other hand you can see how some exotic glyph looks like.
ViewISO requires MUI and TTEngine installed.

New in version 1.1.

- ARexx command 'LoadFont'.
- 'Load' button.
- Accepts font name as a commandline parameter.
- Serious memory leak fixed.

Running from Shell.

ViewISO

ViewISO [fontname]

(loads and displays given font)


If ran from Workbench, always pops filerequester.

Gadgets.

Encoding cycle gadget selects one of 8-bit ISO-8859 encodings. ISO-8859-1
(Western Europe) is the default. 'Upper half' toggle button switches displayed
characters range. When not pressed, characters of codes from 32 ($20) to 127
($7F). When pressed, characters of codes from 160 ($A0) to 255 ($FF) are
displayed. Note that lower half of all the ISO-8859 charsets is always the same.
'Load' button opens up a filerequester to load another font.

ARexx port.

ViewISO has an ARexx port (as every MUI application does). It accepts all
standard MUI commands and a custom one named 'LoadFont', which loads a font of
name given as a parameter. Here is an example of usage:

ADDRESS 'VIEWISO.1'
LoadFont 'FONTS:MyTTFonts/SomeExcellentFont.ttf'

--------------------------------------------------------------------------------

Using ViewISO with filemanagers.

Thanks to its ARexx port ViewISO can be perfectly used as a TrueType font
viewer. 'loadfont.rexx' script is specifically designed for this purpose. It
checks if ViewISO is running, runs it if not and load a font given as a
parameter to the script. Below you can find step by step instruction how to set
up ViewISO as TrueType font viewer in DirectoryOpus Magellan. After the setup
you can view TT fonts just by clicking them in a lister.

1. Prepare TT font filetype.
    a. Open filetype window (from menu 'Settings/Filetypes').
    b. Click on 'Add' button.
    c. In the class definition window add following filetype recognition
       statements: 'Match Name #?.ttf', 'And', 'Match $0001000000??????00??00'.
    d. Give the name and ID to the filetype.
    e. Click 'Use' button.
2. Specify double-click action for the filetype.
    a. In the class actions window double click on 'Double-click' item in the
       left listview.
    b. In the action window click 'Add', change action type to 'ARexx' and enter
       'S:loadfont.rexx {f}'. Note you do not need to keep the script in 'S:'.
       Give your path if you place the script elsewhere ('DOpus5:Rexx' for
       example may be a good alternative).
    c. Click 'Use', then 'Save' in the main filetype window.
3. Specify a path to ViewISO in the script.
    a. Load the script into your favourite text editor.
    b. In line 5 of the script enter the path to ViewISO executable (default is
       'SYS:Utilities/ViewISO'.
    c. Save the modified script.
    
Now you can doubleclick on some TT fonts in a Magellan lister.

NOTE: The script is not prepared specifically for OpusMagellan. It can be used
with any filemanager allowing running ARexx scripts, be it DiskMaster, Opus4,
RO, or Workbench 3.9 DefIcons.
