Converts one or more PDFs into a powerpoint or word document with one pdf page per slide/page
npm install pdf-officegen


A NPM module that accepts one or more PDF files and converts them into one of the following:
1. Powerpoint slides (.pptx)
2. Office Word Document (.docx)
Note: This module is the successor of pdf-powerpoint
It is recommended you weigh the runtime performance and output quality of each engine for
the content you are converting.
1. GhostScript - Converts a PDF into PNGs with one command per PDF
- Debian: apt-get install -y ghostscript
- OSX: brew install ghostscript
1. MuPDF - Converts a PDF into PNGs with one command per PDF
- Debian: apt-get install -y mupdf-tools
- OSX: brew install ghostscript
1. Inkscape - Separates PDFs into single page PDFs and then converts each PDF into PNG
- Debian: apt-get install -y inkscape
- OSX: brew install inkscape
Supported Runtimes: Node > 5.10.0
``javascript``
import {Powerpoint, Word} from 'pdf-officegen'
const p = new Powerpoint([options])
#### Constructor Options
* engineclean
- 'ghostscript' (default)
- 'mupdf'
- 'inkscape'
* - set to false if intermediate image files should be left on the filesystem.jobId
* - if provided, this will be included in any logging outputcropLastImage
* requires ImageMagick convert to be on the path. Will crop the last pdf image before placing on slide, sometimes a line would show up if the last PDF page was a partial page.dimensions
*
- width - of slides in pixels (default: 800)
- height - of slides in pixels (default: 600)
- type - options: '35mm' 'A3' 'A4', 'B4ISO' 'B4JIS' 'B5ISO' 'B5JIS' 'banner' 'custom' 'hagakiCard' 'ledger', 'letter' 'overhead' 'screen16x10' 'screen16x9' 'screen4x3' (default)
`javascript`
p.convertFromPdf('input.pdf', [options,] (err, result) => {
//Do something with the result (filepath to output)
})
#### Convert Options
- stagingDir - This is where the pptx file will be generated. stagingDir/img
- Images go in and are automatically removed once the powerpoint file is generated.fs.mkdtemp('${os.tmpdir()}/pdf_ppt_')
- If not provided the default is to use to generate a random temp directoryconvertOptions
- - These are used for Ghostscript conversiondensity
- - specifies the PPI setting for the output image
- default: 72, maximum value allowed is 300

Events are emitted for any client wishing to capture timings or react to incremental artifacts.
The EventEmitter2 library is used, which means you
can write a single listener for all events if you wish.
Events emit an object that may have the following properties:
- error - if an error occurredtime
- - if the event marks the end of a corresponding start eventoutput
- - If there is a PNG or PPTX file generated from the event
#### Event Names
- err.png.all done.png.all
- - output is an array of paths to images generated from PDFdone.png.clean
- - output is the image directory that was deleteddone.[pptx|docx].creation
- - powerpoint is complete in memory, all images added to slidesdone.[pptx|docx].saved
- - output is the pptFileerr.[pptx|docx]
- - error is the error the was thrown from officegen
##### Inkscape Engine
- done.pdf.separate - output is the command executeddone.inkscape.export
- - after each inkscape conversion completes, output is the command that was executeddone.inkscape.export.all
- - after all inkscape conversions are complete
##### GhostScript Engine
- done.gs.convert- output is the GhostScript command that was executedcropLastImage
- Only when option is setdone.im.convert
- - after the last image of each PDF is converted done.im.convert.all
- - after all images are croppederr.im.convert
- - if any of the image cropping operations fails
##### MuPDF Engine
1. done.mupdf.convert - output is the MuPDF (mudraw) command that was executed
Debug is used for logging and there are three namespaces you can enable.
* pdfppt:app
* pdfppt:debug
This can be turned on by setting DEBUG=pdfppt:*, read more about Debug here

GhostScript Option Documentation
This module uses the following command: gs -q -dQUIET -sDEVICE=pngalpha -r150 -o outputFile-%d.png
#### GhostScript Tips (not this module's API)
- As a convenient shorthand you can use the -o option followed by the output file specification as discussed above. The -o option also sets the -dBATCH and -dNOPAUSE options.-q
- Quiet startup: suppress normal startup messages, and also do the equivalent of -dQUIET.-dQUIET
- Suppresses routine information comments on standard output.-sDEVICE=pngalpha
- -r[XResxYRes]` Useful for controlling the density of pixels when rasterizing to an image file. It is the requested number of dots (or pixels) per inch. Where the two resolutions are same, as is the common case, you can simply use -rres.
