Image To ZX Spec 1.3.3 Released

Full colour conversion

Image To ZX Spec is an image and video converter that can produce "Spectrumized" retro art images of any size and convert real work to use on the ZX Spectrum, an emulator as a slideshow or video. This is useful to create music videos, posters, mock screenshots, to name a few - you do not even need a Spectrum to use this program!

Features:

• Convert most avi formats/divx video to anim gifs or virtual tapes (for use in an emulator or on a real Spectum)!
• Convert any image to a format a real Spectrum can display.
• Convert any image to a full (original) size image with a retro Spectrum effect.
• Multi core high speed conversion - configurable!
• Fully automatic conversion, you just choose how you want to apply the effects.
• Pre processing (brightness colour etc.) options.
• Multiple dither (colour correction) options - 15 in total, that's excluding image to text and no dither options!
• Multiple previews of all the dither options.
• Many colour modes, such as monochrome, full 15 colour and the exotic "Gigascreen" colour mode (102 colours on a ZX Spectrum!)
• Localised GUI - German, Greek, Italian, Polish and Spanish

Image To ZX Spec 1.3.0 Released

Update: Version 1.3.1 is now available here.

Version 1.3.0(_01) of this application has now been released and is freely available.



Image To ZX Spec 1.3.0 is a multi core capable image and video converter that can produce vintage computer art images (jpeg/png) of any size and can even convert work to a real ZX Spectrum (or an emulator) as a slideshow or video. This is useful to create retro 8bit music videos, posters, tshirts, mock screenshots etc etc - you do not even need a Spectrum to use this program!



New for 1.3.0 - With the exception of the first Ubuntu (15 colour) screenshot above (the tool works on Windows and Ubuntu), the other screenshots illustrate the new GigaScreen 102 colour palette option. For more images and information on Image To ZX Spec's full capabilities read here. GigaScreen images are viewable on any Spectrum with a suitable GigaScreen viewer program. The large palette is a product of flashing two specially prepared images in sequence and due to persistence of vision extra colours can be seen. The real colours are displayed in Image To ZX Spec's preview and saved in other image file formats (png/jpeg) capable of being shown on a PC.



What reviewers have had to say:
"Great tool..."
(kgmcneil, World Of Spectrum)

Amazing stuff and works perfectly with SpecEmu.
(Pegaz, World Of Spectrum)

Awesome...
(orange, World Of Spectrum)

I like the option that you can see the result of different methods at the same time and can choose the one I like the best.

Hot on the heels of the 1.0.3 release I burnt out to finish 1.0.4 with a number of new ordered dithering options, performance tweaks and other nice things - try it online (requires Java 6, you will be shown a security prompt) or download it (more links bottom of this post beneath changes).

You can find out more about what Image to ZX Spec can do here

Here's a sample of the new ordered dither modes, note that although the Spectrum only has 7 effective colours (excluding half bright) the dithering achieves the appearance of many more...

Version 1.0.4
- Added Ordered Dithering and a substantial number of new modes
- Added options control for ordered dither intensity
- Refactored some old code giving a small performance increase
for screen export and error diffusion dithering

Image to ZX Spec 1.0.3 Released

Lots of improvements in this release - as you can see! For a change list see below, for more info and screenshots see the original post.

If you don't fancy the download you can also now try Image to ZX Spec online (requires Java 6). You will be prompted about its digital signature being unverified - you will need to click the "Run" option or it won't start). You don't have to tick the "Always trust..." option.

-------

- New dithering options (including Low Error Atkinson)
- New jpeg image export option
- New pre-processing options such as brightness, contrast etc.
- New image scaling options (proportional scaling)
- Monochrome image mode with colour selection
- Small code refactor, improvements in speed on some operations
(speed is not a priority at the moment).

Version 1.0.2 (Internal build only)
- Numerous new dithering algorithms added
- Small bug fixes

Image to ZX Spec 1.0.2 Progress

I thought I'd post progress on Image to ZX Spec. I've now added a number of other dither options and a separate dialog for configuration, but I guess what you really want to see is how much it's improved - the following conversions where done with my own "low error" dither based on the Atkinson dither. Click the images to see them full size. Yes... this is what the images will look like on a real ZX Spectrum!

Image to ZX Spec 1.0.1 Released

Image to ZX Spectrum has been updated.

For a full description of what this application does see the original post.

I'm not entirely happy with this release - the "Full Colour Floyd Steinberg Converter" (FCFSC) mode is still quite poor, however I'm releasing it now so users can get a feel for the "Half Colour Floyd Steinberg Converter" (HCFSC) which is new to 1.0.1 and is potentially a lot better (pre release screenshot above).

Version 1.0.2 will fix the colour issues in FCFSC.
