If you’re a fan of 8-bit art then you will already be aware of the FLI function on the C64 & C16/Plus 4.  FLI stands for Flexible Line Interlace and was and still is widely used within the C64 scene.   The difference for the C16/Plus 4 is that we have access to a greater number of lumanances/colours than the C64, and the TED chip handles the image in a different way allowing some superb presentations.

 

The Guide

 

 

 

Rather than going into all the math/technical point of view of FLI, I’m going to be concentrating on how as a user we can use this technique to produce some outstanding images for our personal collections.

 

 

 

 

I’ve found the best program to use is “P4PC FLI Converter

”, from Balázs Kiss.  This is a Java program that can be used on either Windows or OSX, I havent tested it on Linux yet.  So straight away we have a universal convertor.

 

 

 

·      Converting the picture.

o   Start by choosing your images, best to have image size of 320x200.

 

o   Open P4PC_FLI_Convertor/convertor/p4pc_by_larry.jar

o   Open the colortable, select Plus4 color table

o   Open the desired picture, then click start with Plus 4 mode activated.

o   Save the FLI, as a PRG straight from this program

·      The next step depends whether you’re going to view your image on a real machine or emulator.  For the purpose of this example, we are talking about a real Plus 4.

o   Using your favourite file transfer method.  Mine is CBM4WIN, and a XM1541 cable.  Save your newly created image.prg’s and the _showfli$1100.prg (The Player) onto the same disk.

o   Load the player from disk

LOAD “_showfli$1100.prg”,8,1

LOAD “image.prg”,8,1

o   Type in the following command

SYS 4352

 

 

 

This method can be performed on a Emulated C16/Plus 4, I would recommend

YAPE for this.

 
 

 

 

The first time I saw this method, I was so impressed.  Especially when I converted a game screen of Doom.  This is definitely an eye opener and a great way to demonstrate the capabilites of the C16/Plus 4.

 

 

 

 

If you want more examples of what can be done, you only have to look at some of the demo’s over at

Plus 4 World.

A while ago a application for the Iphone was released to convert images taken by the camera or in the album in Spectrum images, output as program or image.  What would be amazing if there was a application like that for the C16/Plus 4, you could take FLI images on the fly.......  But maybe that is just a dream. 

Hope you found this article useful.
