Online "retro" image tool
Here's a small online tool to convert/view images from/to the IFF format: http://tool.anides.de
The tool runs completely on your machine in your browser so there's no communication with a server at all. Use drag and drop or click on the background to load the image(s). Choose "Save" to download the converted IFF image. Please note that a recent version of Firefox or Chrome is recommended and also that the IFF support is not complete. Here's an example screenshot of the website. Sascha |

a pretty neat tool.
Would be nice to see some scaling / cropping options, and some more dithering types available. For myself I'd like to see the inclusion of a ZX Spectrum palette too |

A simple scaling is pretty easy to add but cropping involves some user interaction. Not impossible but the UI need some serious improvement for that. As far as I know the ZX Spectrum palette is limited to two colours per 8 x 8 block, am I right? Do you have some suggestions for other dithering algorithms? IMHO the implemented Floyd-Steinberg is almost unbeatable so far. |

http://www.tannerhelland.com/4660/di...s-source-code/ Cool tool BTW! Edit: A suggestion: The Enterprise 64/128 computer uses a 256 RGB palette (2 bits blue, 3 bits for green and red) and it could be interesting to see how it could render a modern picture Last edited by Megol; 05 February 2015 at 15:45. |

The 16 colors dithered is too pixelated. The best program to convert to iff is Ultimate Paint.
This is a png screenshot of the 16 colors dithered iff image: http://hostthenpost.org/uploads/e805...538e8c6914.png Last edited by Retrofan; 21 March 2016 at 19:46. |

Comparison left to right Retrofan, Anima, BigFan
all in 320 x 200 x 4 i've swapped one facial color for blonde hair instead of clay tone. Can't say Ultimate Paint suits my needs |

BigFan your conversion is better. What program did you use?

Nice!
Would it be possible to have it support HAM mode too? P.S. I would _love_ to have that beautiful girl here, too |

Its not always a case of which is 'best' but often has a massive impact on artistic style. Sometimes a 'worse' choice of dither, or just messing with the dither settings produces a more interesting result. I have two canvases in my bedroom, one of myself as a child and one of my wife in her early 20s, both have used a similar program to this to produce artwork in the ZX Spectrum style. (in fact, i even load up the output into a ZX emulator to be sure of accuracy) http://www.redbubble.com/people/hung...x-spectrum-art http://www.redbubble.com/people/hung...x-spectrum-art the artistic purpose of such works, is certainly not about producing the most 'accurate' looking picture, but the most interesting. I hope this gives some understanding as to why i am interested in such a tool |

Nice choice of model I haven't seen much of Gemma since she left Hollyoaks (other than Soapstar Superstar, I'm A Celebrity... Get Me Out Of Here (a few years back) and she was also in one of the Command & Conquer games). I will try your tool in Firefox 3 and see what happens... Edit: Beaten by Hungry Horace, grrr...

However IMHO it would be better to be able to select e.g. 8 colors from the 256 color palette, given that the Enterprise only supports freely selectable colors in a low resolution mode (80x256 pixels). In the most commonly used mode (160x256 pixels) one have 16 colors however only the 8 are freely selectable. Given the support for the Atari ST palette (with one extra color bit) it shouldn't be that hard? |

A new palette entry "256 (8-8-4)" (Enterprise 64/128) has been added.
Examples (16 / 256 colors): Edit: oh, you mentioned 8 colours so here are 8 / 256 examples: Last edited by AnimaInCorpore; 08 February 2015 at 12:30. |

Yes, it also depends very much on the image content to get a "good" result using a rather simple conversion. IMHO to optimize the result you always need to modify the image before like aligning some ROI elements on a 8 x 8 pixel border. Well, that's really an interesting challenge...

Update: a first attempt at converting images to the ZX Spectrum graphics format has been added. The quality of the result ranges from totally awful to acceptable.
Some notable results: |
