Here is my complete nodejs API function below: Docx to html:ĮnvertDocxToHtml = catchAsync(async (req, res, next) => )Įxports. Convert docx to html:īoth module is working fine but problem is, when I am converting any html to docx from my website and then trying to convert it into html again, it's giving the response below and do not providing any html as value. I am using the following npm module below for converting. Where the two resolutions are same, as is the common case, you can simply use -rres.Last few days I am fetching problem with my project when I am converting docx to html and after edit the html with angular editor I am saving the html into docx file again. It is the requested number of dots (or pixels) per inch. -r Useful for controlling the density of pixels when rasterizing to an image file.-dQUIET Suppresses routine information comments on standard output.-q Quiet startup: suppress normal startup messages, and also do the equivalent of -dQUIET.The -o option also sets the -dBATCH and -dNOPAUSE options. As a convenient shorthand you can use the -o option followed by the output file specification as discussed above.This module uses the following command: gs -q -dQUIET -sDEVICE=pngalpha -r150 -o outputFile-%d.png GhostScript Tips (not this module's API) Results in (GhostScript): 'gs' -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 '-sDEVICE=pngalpha' -dTextAlphaBits=4 -dGraphicsAlphaBits=4 '-r72x72' -dFirstPage=5 -dLastPage=5 '-sOutputFile=/tmp/magick-94224ozuZS3iFphAj%d' '-f/tmp/magick-94224zWXBFMw8ZiEA' '-f/tmp/magick-9422413LS3T1dhoL4'.ImageMagick: convert -density 72 -quality 100 -verbose '/tmp/output.pdf' '/tmp/img/output-4.png'.This library originally used ImageMagick but it was discovered that ImageMagick delegates to GhostScript for PDF -> PNG conversion, so GhostScript is used directly This can be turned on by setting DEBUG=pdfppt:*, read more about Debug here Developer Guide - output is the MuPDF (mudraw) command that was executedĭebug is used for logging and there are three namespaces you can enable.err.im.convert - if any of the image cropping operations fails.

done.im.convert.all - after all images are cropped.

done.im.convert - after the last image of each PDF is converted.

done.gs.convert- output is the GhostScript command that was executed.

- after all inkscape conversions are complete.

- after each inkscape conversion completes, output is the command that was executed.

error is the error the was thrown from officegen

done.creation - powerpoint is complete in memory, all images added to slides.

- output is the image directory that was deleted.- output is an array of paths to images generated from PDF.output - If there is a PNG or PPTX file generated from the event.time - if the event marks the end of a corresponding start event.The EventEmitter2 library is used, which means youĬan write a single listener for all events if you wish.Įvents emit an object that may have the following properties: default: 72, maximum value allowed is 300Įvents are emitted for any client wishing to capture timings or react to incremental artifacts.density - specifies the PPI setting for the output image.convertOptions - These are used for Ghostscript conversion.

convertFromPdf ( 'input.pdf', ( err, result ) = > /pdf_ppt_') to generate a random temp directory

Inkscape - Separates PDFs into single page PDFs and then converts each PDF into PNG.

MuPDF - Converts a PDF into PNGs with one command per PDF.GhostScript - Converts a PDF into PNGs with one command per PDF.It is recommended you weigh the runtime performance and output quality of each engine for The binaries are installed for your runtime, they are not packaged with this module. This library currently supports three options. The same functionality is also available if you are building a Node.js app. You can do this in a vanilla JS app, React, or any other framework of your choice. Slides are in the order of the PDFs passed in the arrayīased on the requirements of your application, one rendering engine may be more appropriate Everything to generate DOCX and save as a PDF is done in client-side JavaScript without any MS Office or server-side dependencies.Each single images is added to a slide in the powerpoint presentation.A rendering engine is used to transform each page of a PDF into a PNG image.Note: This module is the successor of pdf-powerpoint General workflow A NPM module that accepts one or more PDF files and converts them into one of the following:
