| 23 | <p> <tt>pic2oric</tt> converts images to the Oric Atmos colours. The Oric |
|---|
| 24 | Atmos screen format is one of the most twisted standards and very little |
|---|
| 25 | artwork exists for this vintage computer. It was therefore the perfect |
|---|
| 26 | challenge for the Caca Labs image processing team. </p> |

| 28 | <h2> Downloads </h2> |
|---|
| 29 | |
|---|
| 30 | <p> The <tt>pic2oric</tt> source code may be downloaded from <tt><a |
|---|
| 31 | href="pic2oric.c">pic2oric.c</a></tt>. It currently only runs on Linux and is |
|---|
| 32 | extremely slow (around 1 minute to process an image on a modern computer). </p> |
|---|
| 33 | |
|---|
| 34 | <h2> Screenshots </h2> |
|---|
| 35 | |
|---|
| 36 | <p> These images show how <tt>pic2oric</tt> performs. The results may not |
|---|
| 37 | seem terribly clean, but they are probably better than anything that has |
|---|
| 38 | been seen so far on an Oric Atmos computer. </p> |
|---|
| 39 | |
|---|
| 40 | <p> These first 4 images show the results on the same images than the ones |
|---|
| 41 | on Dbug’s <a href="http://www.defence-force.org/computing/oric/coding/annexe_3/pictconv/">PictConv</a> website, to illustrate the improvements over the |
|---|
| 42 | traditional RGB separation technique. </p> |
