- This program is dedicated to the memory of Jamie Main, my
- best friend, co-worker, and fellow Amigoid who left this life
- behind quite abruptly on August 15th, 1990.
-
- ****************************************************************
-
- IFFCHR is an Amiga graphics utility that will translate
- non-HAM IFF screens into character graphics text files that
- approximate the same shapes and colors as in the original
- screen.
-
- IFFCHR is primarily targeted for BBS users who want to
- participate in "ANSI artwork" message bases. These sections
- of the BBS will allow color changes and other text screen
- functions through the use of ANSI control characters.
-
- Although nothing is implied in the ANSI standard, the use
- and proper viewing of BBS-style ANSI usually requires both a
- standard 8-color palette and the IBM extended ASCII
- character set to be present. This can be achieved through
- use of "colorbench" and Preferences to achieve the proper
- colors, while the IBM extended ASCII can be found in the
- Amiga font "ibm5.font". Use FED to change this font to
- non-proportional, if necessary, and then use FF to install
- the font globally.
-
- As an alternative, a limited ANSI viewer is included for
- viewing IFFCHR examples. The viewer is called "ReadCHR"
- and is restricted to color changes only. No cursor
- movements, bold colors, etc, are supported by ReadCHR at
- this time.
-
- Many of you may be familiar with various "ANSI paint"
- programs used to create ANSI artwork. While IFFCHR will
- produce ANSI text, it does so in a very different way.
- Rather than trying to create a graphic in low resolution
- ANSI character graphics, IFFCHR allows you to use the IFF
- format to create your art first in high resolution. It then
- translates that directly into ANSI text.
-
- IFFCHR also produces black and white ANSI, and "plain
- vanilla" ASCII graphics. The ASCII can be loaded into a
- word processor for editing.
-
- ****************************************************************
-
- Here is a brief rundown of the options you'll be
- presented with...
-
-
- Read from... Enter the file name of the non-HAM IFF
- screen you wish to convert here.
-
- Save as... File name to save by.
-
- Color When set to "Color", ANSI color control
- (toggle) characters will be used. The IFF screen
- will be re-mapped to the target palette.
-
- When set to "No Color", only black and
- white colors are used for ANSI. The IFF
- screen will be re-mapped using dot-densities
- to a 2-color palette. If "ASCII only" is
- selected (see next menu), no color control
- characters will be output.
-
- Graphic Font When set to "Graphic Font", the IBM
- (toggle) extended ASCII character set will be used
- in the output. This allows several extra
- characters to be used in the translation,
- providing greater detail. An IBM 8 type of
- font is required for viewing the results.
-
- When set to "ASCII only", plain vanilla
- ASCII text is used in the output. Also,
- various characters such as "." and "\"
- will be excluded to avoid popular control
- characters used on several ASCII-only BBS
- programs. The resulting file can also be
- edited in a word processor.
-
- Line Feeds This toggle selects between two
- only end-of-line combinations. Either
- (toggle) line feeds only can be selected, or
- carriage returns in combination with
- line feeds.
-
- About Credits and information.
-
- Line Length Length of lines in final text output.
- Although most BBS programs are 80 column,
- there is often a prompt of one of more
- characters at the beginning of each line.
- Line lengths of 77 will usually get around
- this problem.
-
- Gray Level IFFCHR uses this value to determine cutoff
- levels in palette conversion. This value
- is used in both Color and No Color modes.
- A higher setting here will increase
- contrast, but will also limit the number
- of colors used.
-
- Start Activates conversion routine. During
- conversion, work can be viewed and aborted
- early with a left-mouse-button click.
- The abort option is active when the mouse
- pointer changes to an EXIT sign.
-
- Window Close This standard window gadget in the upper
- left corner of the options screen will
- terminate the session.
-
- ****************************************************************
-
- IFFCHR performs approximately 12,160 comparison tests per
- character output. This amounts to over 24 million
- comparisons on a 80x25 character screen in which there are
- no solid areas of color. In solid patches, IFFCHR
- immediately outputs a blank space to save time.
-
- The results you get from IFFCHR correspond directly to
- the quality of the IFF screen that is input. This is
- especially true when it comes to palette decisions and the
- level of detail contained in the graphic. These factors are
- altered to a degree by the "gray level" setting in IFFCHR
- options gadget window, but are better off determined while
- in the process of creating the IFF itself.
-
- Using a paint program or other graphic utility will
- allow you to condition the screen for optimum conversion
- characteristics.
-
- Included with IFFCHR are some examples of its output.
- Icons are provided for Workbench use with IconX in the C:
- directory, or "ReadCHR" can be used from CLI to view the
- examples in the following format:
-
- ReadCHR filename
-
- The examples provided here with extensions of ".ans" or
- ".asc" can be viewed with this utility.
-
- ****************************************************************
-
- Unregistered versions of IFFCHR will insert a small ad
- in the output of the program. Registered versions will
- have this hindrance removed. The unregistered version is
- freely redistributable. The registered version is NOT. To
- register, send your name, address, and a check or money
- order for $12 (US) to:
