- Run the 279 CIAT author corrections on CGSpace

## 2017-03-02

- Filed an issue on DSpace issue tracker for the `filter-media` bug that causes it to process JPGs even when limiting to the PDF thumbnail plugin: [DS-3516](https://jira.duraspace.org/browse/DS-3516)
- Discovered that the ImageMagic `filter-media` plugin creates JPG thumbnails with the CMYK colorspace when the source PDF is using CMYK
- Interestingly, it seems DSpace 4.x's thumbnails were sRGB, but forcing regeneration using DSpace 5.x's ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see [10568/51999](https://cgspace.cgiar.org/handle/10568/51999)):

```
$ identify ~/Desktop/alc_contrastes_desafios.jpg
/Users/aorth/Desktop/alc_contrastes_desafios.jpg JPEG 464x600 464x600+0+0 8-bit CMYK 168KB 0.000u 0:00.000
```

- This results in discolored thumbnails, sRGB and CMYK:
