# Tools used for Volumetric Regimes |
|||
|
|||
Before you can run these scripts, they will need to be made executable. |
|||
|
|||

## OSP-tools.pdfutils: `color_convert.sh` |
|||
|
|||
**Convert PDF RGB to only-Black** |
|||
|
|||
This will convert an RGB PDF (even if it appears only black) to `input-K.pdf`. |
|||
|
|||
./color_convert.sh black input.pdf input-K.pdf |
|||
|
|||
Link: <http://osp.kitchen/tools/pdfutils/> |
|||
|
|||
## OSP-tools.pdfutils: `rgb2cmyk.sh` |
|||
|
|||
**Convert PDF from RGB to CMYK** |
|||
|
|||
Dependencies: |
|||
|
|||
- `gs` (Ghostscript) |
|||
- `pdftops` |
|||
- `control.txt` |
|||
- `apple_to_jNP_photo.icc` |
|||
- `apple_to_jNP_neutral.icc` |
|||
|
|||
This will convert a PDF to `input-cmyk.pdf`. |
|||
|
|||
Usage: |
|||
|
|||
./rgb2cmyk.sh input.pdf |
|||
|
|||
Link: <http://osp.kitchen/tools/pdfutils/> |
|||
|
|||
## Custom VR tools: `make-images-bw.sh` |
|||
|
|||
Dependencies: |
|||
|
|||
- `imagemagick` |
|||
|
|||
This will create a copy of an image folder, with all images converted to BW. |
|||
|
|||
Usage: |
|||
|
|||
./make-images-bw.sh ./images-folder/ |
|||
|
|||
## Custom VR tools: `convert-to-PDFX-3-2002.sh` |
|||
|
|||
Dependencies: |
|||
|
|||
- `texlive-xetex` (xelatex) |
|||
|
|||
This will convert a PDF into the PDFX/3:2002 format + edit the PDF metadata. |
|||
|
|||
Edit PDF metadata: |
|||
|
|||
Open the xelatex template (`xelatex-PDFX-3-2002.template.tex`) and edit the metadata on line 7-12. |
|||
|
|||
Usage: |
|||
|
|||
convert-to-PDFX-3-2002.sh input.pdf output.pdf |
|||
|
|||
## Other useful tools |
|||
|
|||
- Check metadata of PDF: `pdfinfo filename.pdf` |
|||
- Check color space of PDF: `pdfimages -list filename.pdf` |
