pdfcpu's Introduction

pdfcpu: a Go PDF processor

pdfcpu is a PDF processing library written in Go supporting encryption. It provides both an API and a CLI. Supported are all versions up to PDF 1.7 (ISO-32000).

Support for PDF 2.0 is basic and ongoing work.

Motivation

This is an effort to build a comprehensive PDF processing library from the ground up written in Go. Over time pdfcpu aims to support the standard range of PDF processing features and also any interesting use cases that may present themselves along the way.

Focus

The primary emphasis is on providing robust assistance for batch processing and scripting through a comprehensive command-line interface. Simultaneously, pdfcpu aims to simplify the integration of PDF processing into your Go-based backend system by offering a versatile set of commands.

Contributing

What

Please create an issue if you find a bug or want to propose a change.
Feature requests - always welcome!
Bug fixes - always welcome!
PRs - let's discuss first or create an issue.
pdfcpu is stable but still Alpha and occasionally undergoing heavy changes.

How

The pdfcpu discussion board is open! Please engage in any form helpful for the community.
If you want to report a bug please attach the very verbose (pdfcpu cmd -vv ...) output and ideally a test PDF that you can share.
Always make sure your contribution is based on the latest commit.
Please sign your commits.

Reporting Crashes

Unfortunately crashes do happen :( For the majority of the cases this is due to a diverse pool of PDF Writers out there and millions of PDF files using different versions waiting to be processed by pdfcpu. Sometimes these PDFs were written more than 20(!) years ago. Often there is an issue with validation - sometimes a bug in the parser. Many times even using relaxed validation with pdfcpu does not work. In these cases we need to extend relaxed validation and for this we are relying on your help. By reporting crashes you are helping to improve the stability of pdfcpu. If you happen to crash on any pdfcpu operation be it on the command line or in your Go backend these are the steps to report this:

Regardless of the pdfcpu operation, please start using the pdfcpu command line to validate your file:

$ pdfcpu validate -v &> crash.log

or to produce very verbose output

$ pdfcpu validate -vv &> crash.log

will produce what's needed to investigate a crash. Then open an issue and post crash.log or its contents. Ideally post a test PDF you can share to reproduce this. You can also email to [email protected] or if you prefer Slack you can get in touch on the Gopher slack #pdfcpu channel.

If processing your PDF with pdfcpu crashes during validation and can be opened by Adobe Reader and Mac Preview chances are we can extend relaxed validation and provide a fix. If the file in question cannot be opened by both Adobe Reader and Mac Preview we cannot help you!

pdfcpu's Issues

split pdf into n pages

Right now splitting generates a pdf per page.

pdfcpu split ~/test.pdf ~/

I'd like to split the pdf into 2 pages per split.
I am wondering if I am missing something or whether that's just not supported.

UTF-8 Support

Does this library supports UTF-8? Looking for pdf generator which supports Chinese characters.

Thanks & Rgds,
Nanthini

Image conversion to PDF using GraphicsMagick

GraphicsMagick generates 1.2 pdf and they fail using pdfcpu with error dereferenceObject: problem dereferencing object 11: parse: corrupt name object. The files work fine everywhere I have tried them
Do you support back version of pdf?
Don French

Getting the Page Count

I am struggling a little with the API. All feels quite low level.
My goal is to just figure out the number of pages of a PDF.

Got some pointers?

Would also make a nice little example for the API usage.

PDF stamping: Is it possible with current merge functions?

Thank you for your awesome project! Hurray! I was waiting something like that for loooong time

Can you verify if I could stamp a pdf file with an another pdf file using the merging facility?

Cheers! Dimitris

PDF Form filling

Any plans for PDF form filling? PDF "flattening" would be a nice feature to go along with that.

Thanks!

Add PageCount example

This is a great package. Thanks for building this.

I have a quick request: is it possible for you to add an example of how to get PageCount for a given PDF?

PDF stamp and WaterMark - Not showing as expected for PDFs generated from chrome

Hi,

For pdf generated from excel, stamp and watermark is showing as expected.
But pdf generated from chrome browser "print save as PDF" option, stamp and watermark is not showing properly.

Please find attached PDF files.

chrome.pdf
chrome_new.pdf
excel.pdf
excel_new.pdf

Thanks

godocs link leads to "Not Found"

Within the README the link https://godoc.org/github.com/hhrutter/pdfcpu leads to a "Not Found" page
Has the page migrated? Thanks!

Correct update of the ID array for file identification

Ensure proper updating of the trailer dict ID entry.

the first entry( element 0) identifies the original document.
the second entry (element 1) identifies a modified/updated document.

Any processing of a PDF that results in another PDF has to generate the ID array entry such that:

element 0 is a copy from the original document
element 1 is a new calculated MD5 hash as per the rules of the PDF spec.

PDF Export to Image

Hey,

Thanks for this amazing library.

I wanted to know if there is any way to export/convert the PDF to an image (jpeg/png) currently using this package. I have a use case where it would be really helpful. I am looking for an alternative to solutions like running Ghostscript (Imagemagick) and libpoppler which can do this conversion. I can perform all other things for my use using pdfcpu but the final step to convert the pdf to an image seems to be missing, for which I need to rely on popping to the shell. Maybe I missed it in the docs, if it is not available, is there any way to implement this? I would be happy to contribute writing this feature. I also think it would be useful to other users.

parse trailer

scanTrailerDict() would get error ”unterminated dictionary“ when the trailer content like "trailer
<< /DecodeParms <</Columns 5 /Predictor 12>> /Size 126989 ........ >>.
it only get the truncation "<< /DecodeParms <</Columns 5/Predictor 12>>"....

提取PDF文本

请问如何提取PDF文件的内容？ExtractContent方法是dumps "PDF source"？那么如何提取文本格式的内容呢？谢谢！

LZWDecode filter not working

In order to make the LZWDecode filter work and respect the EarlyChange parameter we need to find a way to marry the already existing tiff lzw reader in the experimental golang.org/x/image/tiff repo with compress/lzw. Extending compress/lzw would be the ideal solution for any pdf package.

replacing text in a PDF

Seems i have a similar need to the InProgress pull request
#1

I just want to walk the PDF and replaces the Text

my uses case is that i have these 2D CAD drawings with text in them and need to Translate the text producing a new PDF.

embed hocr (invisible text)

tesseract (and by extension gosseract) produce an html/xml format called hocr containing information about the text that was ocred

I'd like to be able to embed this in my pdfs (like https://github.com/tmbdev/hocr-tools/blob/master/hocr-pdf) but I'm stuck at trying to add the invisible font :(

Any help you can offer along those lines would be awesome.

Using pdfcpu API from []byte

Hello,

It seems all API is oriented to read and write content from and to file (os.file).
Is there a simple way to use it from and to []byte (in order to include them in back of an HTTP API for ex.) ?

AcroForms support

There is a reference to AcroForms in the test PDF code but is their a way for me to populate a fillable PDF with data programmatically? I already have a bunch of fillable PDFs but was hoping to use Go and not something like Apache PDFBox (Java) to accomplish this. I also can't use something like PDFtk because of licensing.

Adding Documentation

I was looking through the code base and I'd like to add more documentation for anyone who'd like to contribute in the future. Plus, I think it'd give me a much better understanding of the code base in general.

Image optimization

Is there any functionality to easily replace images in pdfs?

I'm thinking extract images -> run through jpg size optimizer (eg. mozjpeg) -> replace source image in PDF in order to further optimize PDF size.

The extraction is straightfoward obviously, unsure about replacing. I'm beginning to dig through the golang code but I'm not very familiar with the language. Do you have a simple way in mind? If not, I guess I found the excuse I've been looking for to learn Go...

Error when merging file

Having error, when trying to merge pdf files into 1

dereferenceObject: problem dereferencing object 7: parse: duplicate key

  _, err = pdfcpu.Process(pdfcpu.MergeCommand(filePaths, baseDir+".pdf", pdfcputypes.NewDefaultConfiguration()))

UPD: Pdf files were generated by electron

General ToDo list

@campoy

Review Interface in filters package
Substantial conversions between string and []byte => excessive memory allocation?
Make fit for actual usage as library.

Question/Feature: Unpacking CSV file from encrypted PDF file using UserPW?

Hi @hhrutter ,

I receive bank statement in CSV format. As they can't put a password for CSV file, they embed CSV file inside a PDF file and put a user password for PDF file and send it via email.

My job is to fetch this email and extract PDF file and then unpack CSV file from this pdf and save it to DB.

Currently i follow below steps:

Fetch email attachment
Decrypt PDF file using qpdf
$ qpdf --decrypt --password=myUserPassword inputPdfFile decryptedFile
Unpack CSV file using pdftk
$ pdftk decryptedFile unpack_files output folder
Push CSV file to DB

Can i do step 2 & 3 using pdfcpu?

I have tried step2 using pdfCPU but i am getting below error

Read failed.: ownerpw not ok and insufficient access permissions

I don't have ownerpw as banks won't share it. I have only userpw.
Is it possible to decrypt pdffile without ownerpw like in qpdf where i use just userpw?

Also any plans to support unpack_files option?

Thanks for this wonderful package. I really love it. Currently i am using this for merging pdf files.

Remove reliance on files as much as possible

You should use io.Reader and io.Writer as much as possible to make your library usable in multiple scenarios.

Also for extraction, leave out the file naming and what to do with the exracted content to the library user.

Here is how I managed to do it for Image extraction:

// PDFImageType describe the image file extension
type PDFImageType string

const (
	// JPG jpeg image
	JPG PDFImageType = ".jpg"
	// JPX jpx image
	JPX PDFImageType = ".jpx"
)

// PDFImage provides the content and image format by its extension
type PDFImage struct {
	Body []byte
	Name string
	Type PDFImageType
}

// ExtractImages extracts images to a channel
func ExtractImages(ctx *types.PDFContext, out chan (PDFImage)) {
	for _, i := range sortIOKeys(ctx.Optimize.ImageObjects) {
		ExtractImage(ctx.Optimize.ImageObjects[i], out)
	}
	close(out)
}

// ExtractImage sends image body, ressource name and type to a channel
func ExtractImage(obj *types.ImageObject, out chan (PDFImage)) {
	imageDict := obj.ImageDict

	fp := imageDict.FilterPipeline

	if fp != nil {
		// Ignore imageMasks
		if im := imageDict.BooleanEntry("ImageMask"); im != nil && *im {
			return
		}

		switch fp[0].Name {
		case "DCTDecode":
			out <- PDFImage{Body: imageDict.Raw, Name: obj.ResourceNamesString(), Type: JPG}
		case "JPXDecode":
			out <- PDFImage{Body: imageDict.Raw, Name: obj.ResourceNamesString(), Type: JPX}
		}
	}
}

And then I use it like this:

	var err error
	config := types.NewDefaultConfiguration()
	config.DecodeAllStreams = false

	ctx, err := read.PDFFile("data/somefile.pdf", config)
	if err != nil {
		panic(err)
	}

	err = validate.XRefTable(ctx.XRefTable)
	if err != nil {
		panic(err)
	}

	err = optimize.XRefTable(ctx)
	if err != nil {
		panic(err)
	}

	images := make(chan (pdfextract.PDFImage))
	go pdfextract.ExtractImages(ctx, images)
	for img := range images {
		log.Println(img.Name + string(img.Type))
		// Here you could save the images to files, put them on an object store like S3 or Openstack Swift, resize, crop...
	}

.pdf extension requirement should be case insensitive

I have a pdf with the file extension ".PDF" and was given the output that the file needs extension ".pdf". It's a simple work around to make it work, but the file is properly a pdf so it would be nice if the tool "just worked."

Help message for extract wrong (gives validate text)

Great work @hhrutter - thank you.

I just came upon this minor cosmetic bug as I began to explore the package & thought I should report it.

$ pdfcpu help extract
usage: pdfcpu validate [-verbose] [-mode strict|relaxed] [-upw userpw] [-opw ownerpw] inFile

Validate checks inFile for specification compliance.

verbose ... extensive log output
   mode ... validation mode
    upw ... user password
    opw ... owner password
 inFile ... input pdf file

The validation modes are:

 strict ... (default) validates against PDF 32000-1:2008 (PDF 1.7)
relaxed ... like strict but doesn't complain about common seen spec violations.

converting to PDF/A

It would be great if pdfcpu could be used to convert to PDF/A

	fmt.Printf("creator: %s\n", ctx.XRefTable.Creator)
	fmt.Printf("producer: %s\n", ctx.XRefTable.Producer)

But no matter whether I validate first or not the Producer field is empty.
I would have expected it to be Haru Free PDF Library 2.3.0RC2.
What am I missing?

Failure to open PDF created by Xerox WorkCentre 7225 scanner

Attempting to read a PDF generated by a Xerox WorkCentre 7225 scanner results in the following error:

Error reading the pdf: Read failed.: dereferenceObject: problem dereferencing object 6: pdfFilterPipeline: Expected DecodeParms Array corrupt

I've attached a pdf of a blank page.

To reproduce the error, I basically do this:

        cfg := pdfcpu.NewDefaultConfiguration()
        ctx, err := api.Read("Scanned.pdf", cfg)
        if err != nil {
                fmt.Printf("Error reading the pdf: %v\n", err)
        }

PDF/A conversion/validation

As requested by @tcurdt

It would be great if pdfcpu could be used to convert to PDF/A

How to extract text data from PDF?

I am using below command

pdfcpu extract -mode=content inputFile.pdf outputDir

But i don't know how to convert this PDF-Source into text data.

Can you through some light onto this?

Thanks

Another file fails with this:
pdfcpu import -v 0.pdf 0.tiff
importing images into 0.pdf: [0.tiff]
Import config: A4 595x842 points, pos=full, dx=0, dy=0, scaling: 0.5 relative

0.pdf will be created
Fatal: ccitt: corrupt group4 data

Again this converts with tiff2pdf and I can merge them using pdfcpu merge creating a valid multipage pdf.

After merging pdfs links and references not working

They worked on the original pdfs and after the merge they stop working.
External links also seem to stop working.

optimizeFontResourcesDict: missing fontDict entries "BaseFont" and "Name"

Hi @hhrutter

I have printed some PDF files from http://gluon.mxnet.io/ docs
Then i am trying to consolidate those pdfs using below code

        cmd := pdfcpu.MergeCommand(filenamesIn, outputFile, types.NewDefaultConfiguration())

	err = pdfcpu.Process(&cmd)
	if err != nil {
		logger.Println(err)
		return
	}

I am getting this error

optimizeFontResourcesDict: missing fontDict entries "BaseFont" and "Name"

I am using lastest pdfcpu version v0.1.1 on MacBookPro version 10.12.6

Thanks

Remove fmt logs

Hello,

First of all, great library. Thank you. Thanks for also implementing a Logger interface and the ability to disable logging. However, as I'm trying to split pdf into pages, there are some logs that are actually fmt.

See:
https://github.com/hhrutter/pdfcpu/blob/master/pkg/api/api.go#L316
https://github.com/hhrutter/pdfcpu/blob/master/pkg/api/api.go#L207

Can you update them to use log instead?

Thanks!

Specify the importance of calling pdfcpu.OptimizeXRefTable before dealing with fonts.

Get rid of excessive logging

Libraries and source code has excessive logging interleaved with code that does main work.
This makes reading source code harder.

Lines like:
logInfoValidate.Println("*** validateShadingDictCommonEntries end ***")

Go standard library should be inspiration for this. It has no excessive logging inside library code.
Please get rid of logging inside the library.

validateString: missing object

I am not sure whether this is pdfcpu not supporting PDF/A-2B or ocrmypdf/tesseract generating an invalid pdf. Any idea?

Encrypt fails when ID missing

Encrypting a document relies on the existence of an otherwise optional ID element.
For encryption we need to create an ID element on the fly.

PDFContext non-exportable

Hi Horst,
Nice job !

I want to cache ctx (*PDFContext result of api.Read()) in a gob file but there are two non-exported fields k and v in "entry" type at hhrutter/pdfcpu/pkg/pdfcpu/nameTree.go line 27. Is-it possible, please, to make them exported by modifying their names with Uppercase ?

Many Thanks for your PDF processor.
Pierre

Leave out the logging management to the API user

Take a log interface as parameter instead of forcing them in init(). Leave to the lib user on how display or store them.
The interface should match log.Logger methods.
Put it in the Context.

Extract Metadata

I'd like to create a hash of PDF documents to compare them. The problem: PDFs use timestamps and UUIDs that might be different when you create the PDF - despite having the completely same structure and content. For more context check here

I was wondering if I could parse the PDF and replace UUIDs and timestamps and combine/serialize all this into a digest I could then compare.

Do you think this would be possible with pdfcpu?

Validation fails due to missing BitsPerComponent

I'm attempting to merge some files where one file contains the following:

/Subtype /Image
/Width 20
/Height 1
/ImageMask true
/Decode [1 0]
/Length 11 0 R
/Filter /FlateDecode

When pdfcpu validates this file, it fails because BitsPerComponent is not specified for this particular XObject.

I'm not an authority on PDF, but in the specification there is a table "Optional parameters for LZWDecode and FlateDecode filters" which has the following description for BitsPerComponent: (May be used only if Predictor is greater than 1) The number of bits used to represent each colour component in a sample. Valid values are 1, 2, 4, 8, and (PDF 1.5) 16. Default value: 8.

I think one might argue that since no Predictor is specified BitsPerComponent should actually not be allowed (or at least ignored) for this particular image.

Failed to merge

hi @hhrutter
It's great project!

Now i have a question. The result of merging tow pdf file looks like not correct.
the tow input file:
test3.pdf
test4.pdf

out file:
out2.pdf

code:
`
filenamesIn := []string{"test3.pdf", "test4.pdf", "out2.pdf"}

_, err := Process(MergeCommand(filenamesIn, "out.pdf", pdfcpu.NewDefaultConfiguration()))
if err != nil {
    return
}

for comparing, the output of cpdf :
out1.pdf

recent change causes go get error from upspin

I had to recently move my project to a new machine so the project could go live. I therefore had to run go get on that new machine for pdfcpu. In extract.go you use the following package:

"github.com/hhrutter/upspin/errors"

When running go get github.com/hhrutter/pdfcpu I get the following error:

package upspin.io/log: unrecognized import path "upspin.io/log" (https fetch: Get https://upspin.io/log?go-get=1: proxyconnect tcp: tls: oversized record received with length 20527) package upspin.io/upspin: unrecognized import path "upspin.io/upspin" (https fetch: Get https://upspin.io/upspin?go-get=1: proxyconnect tcp: tls: oversized record received with length 20527)

This should be reverted to the follwing package as is it is only used in one place in that file and all other files of pdfcpu use this package:

"github.com/pkg/errors"

PDF Validation

I am not a PDF expert at all and would appreciate to know people's opinions about how well pdfCPU supports PDF/A validation.
I ask this because i have been taksed with setting up a Digital Preservation system for long term storage of documents and photos.

Background is here:

Its hilarious that the tool requires a Java Virtual Machine. Not very digtial future proof :)

Merge files command order

Hi there @hhrutter, great project!

I'm using the merge command, expecting a final PDF with the exact input order, but the result PDF has a random order.
Am I using the command incorrectly? Should I use another feature? I need to create an output PDF with multiple PDFs in a precise given order.

Thanks in advance

ouputFile := fmt.Sprintf("output/result_%s.pdf", time.Now().Format("20060102-1504")) pdfcpu.Merge(pdfMergeOrder, ouputFile, types.NewDefaultConfiguration())

N-up

A pdf file file.pdf contains 10 pages,

I would like to merge these 10 pages into a long single page pdf file file2.pdf

It is useful when backing up a webpage or excel files.

As far as I know there is only one tool called pdfjam can

do this (by using N-up) but it is not actively maintained for years,

also pdfjam is difficult to install on Windows system.

Any ideas? thanks!
