Unable to resolve module react-native-html-to-pdf ....

When i launch my application i got the "unable to resolve module react-native-html-to-pdf" error.

I try to clear watchman, delete the module and reset the packager cache but no one works. I also relink the libraries, restart xcode and the terminal, clean and rebuild the project reinstall with rnpm .. Do you have any suggestion ?

the warning :

my "project" :

Great Library! Anyway to use custom Fonts in iOS?

I really need to use custom fonts in iOS,
anyway or anywhere should I look to modify the code. I could issue a pull request once done.

HTML from url

Is it possible to convert from url?

Module RNHTMLtoPDF requires main queue setup since it overrides `init` but doesn't implement `requiresMainQueueSetup`

I'm getting this warning in the console:

RCTLog.js:48 Module RNHTMLtoPDF requires main queue setup since it overrides `init` but doesn't implement `requiresMainQueueSetup`. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.

npm install in Example folder has lots of warnings and errors

Hi Christopher,

Thanks for creating this module. I am eager to try out. I noticed that the npm install has several errors on gyp-build. And after npm install, I run "react-native run-ios" and i got the error below:

(node:4626) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
Command run-ios unrecognised

Did I miss anything?

Unable open pdf created with img html tag

Hi,

This is great plugin for react native developers to create pdf. I created normal text pdf. I created as expected.

When I created pdf with html img tag with local image uri,live image url,base64 of image in src attribute ,I m unable to open the pdf.And I note that pdf size is 0 bytes.

Manual paging support?

I jump into a problem currently: set paging manually
Eg: (assume I predefined page size, as options width and height). I have 2 chapters, I need each chapter to be placed on separate pages. If chapter 1 height > options.height then it will render 2 pages, 1st page is full of content, 2nd page is remaining content, the rest is blank. Chapter 2 will start from 3rd page.

How can we solve this problem? I gonna modify native code but I'm not familiar with Objective C

Is there a way to control DPI

I'm trying to print out a custom label using this and the react native print module as well. Is there anyway to control the dpi? I'm having issues with images which are at the right resolution printing at what looks like 72dpi as opposed to the 300 I am aiming for.

thanks

example

Hi Chris,
could you publish a running example? I am not able to view the created PDF.
I have published on Stackoverflow an example that I run (http://stackoverflow.com/questions/41449747/trying-to-generate-a-pdf-and-view-or-email-it-with-react-native/41700362#41700362) , it seems to create the pdf, but I don't know how to view it in order to mail it later.

Many thanks,
Cheufte

Missing non latin characters in android

All cyrillic characters are missing in generated pdf file when I using them in html. Reproduces in android only. I found that iText module is a reason and tried to play with XMLWorkerHelper but with no luck.
Here I found some examples how to resolve the issue, but I can't implement it to your module:

Style Box-Shadow not working on Android

Hi,

greate Libarary. I got a problem with box-shadow style on android. I have a card like element, that looks the following:

<div style="box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2); padding: 8px; margin-top: 16px; margin-left: 4px; page-break-inside: avoid; display:inline-block; width:635px">

On iOS, it looks good, but on android it is not working. The shadow is missing. Any Ideas why or any workarounds?

Error after adding libraries

Something goes wrong after I add RNHTMLtoPDF.xcodeproj to the project and libRNHTMLtoPDF.a to libraries. Any idea what this error means?

Hi,
I use RN 47.0 and html-to-pdf 0.5.0

Problem with img element in Android

Hello. When I use an img tag, it is displayed in iOS but it is not displayed in Android. I have created a repo for this bug. You can find it here: https://github.com/inventrix/qrError

In the index.js file I am rendering a QR code and a button. When the button is pressed, firstly I save the QR code as a png file. Then I create a PDF file that contains this QR file. I did not include the code that displays the generated PDF file but when I pull it out by using 'adb pull' QR image is not displayed in the generated PDF.

Example doesn't work on react-native v0.21

I'm getting undefined is not an object (evaluating 'RNHTMLtoPDF.convert') error from this line: RNHTMLtoPDF.convert(options).then((result) => {

here is my code:

'use strict';

var React = require('react-native');

var {
  AlertIOS,
  AppRegistry,
  NativeModules: {
    RNHTMLtoPDF,
    RNMail
  },
  StyleSheet,
  Text,
  TouchableHighlight,
  View,
} = React;

import template from '../helpers/template';

var HTMLToPDFExample = React.createClass({

  componentDidMount() {
    var options = {
      html: template.html,
      fileName: 'test',
      directory: 'docs',
      height: 800,
      width: 1056,
      padding: 24,
    };

  RNHTMLtoPDF.convert(options).then((result) => {
    RNMail.mail({
        subject: 'Test',
        recipients: [''],
        body: '',
        attachmentPath: result,
        attachmentType: 'pdf',
      }, (error, event) => {
        if(error) {
          AlertIOS.alert('Error', 'Could not send mail. Please send a mail to [email protected]');
        }
      });
    });
  },

Square cropping?

For some reason, my PDFs are coming out on iOS (maybe android too, but I haven't checked) cropped to a square, which I don't understand why is happening.

I'm trying to create the PDF so it fits on a sheet of paper, but the bottom 2 or 3 inches just gets completely cut off and html elements resume as normal at the top of the next page.

Here is an example of the html I have

let s = "<!DOCTYPE html><html><div>Hello</div></html>"
// but imagine having <div>Hello</div> repeated 100 times

My options look like this:

let options = {
    html: s,
    fileName: 'test',
    directory: 'docs',
    base64: true,
    height: 842,
    width: 595,
    padding: 24,
  }

It looks like the page comes out to 595x842, but the area that actually contains elements is cropped to a square (I am just guessing it's 595x595).

Am I doing something wrong, or is there a way to fix this? Thanks!

PS Would be cool to have options for page numbers and borders... stuff that doesn't need to be calculated in respect to the html, but will just show up on each page.

Can't just pass a width, requires height and paginates

Seems the width is only taken into account when a height is also passed.

      const results = await RNHTMLtoPDF.convert({
        html: receiptHTML,
        base64: true,
        width: 226,
      })

produces a default width:

However with a height:

      const results = await RNHTMLtoPDF.convert({
        html: receiptHTML,
        base64: true,
        width: 226,
        height: 800
      })

Renders the width, but also paginates:

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x6040004974d0 H:[UIImageView:0x7fdd82c7a7e0]-(3)-[UILabel:0x7fdd82c78510'Page 1'](LTR)   (active)>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

Custom fonts

Hi,
I want to add a custom font to the html. The font file is in the same folder as where the component is. Problem is that when I try to generate the pdf it gives and exception:
Error: ExceptionConverter: java.io.IOException: ./VarelaRound-Regular.ttf not found as file or resource.
I have included this line for custom font: fonts:['./VarelaRound-Regular.ttf']
Note: app is working correctly with out the fonts option.
Thanks

landscape mode

Is it possible to generate PDFs in landscape mode with this library?

I tried adding the following CSS but it has no effect on the orientation:

<style type="text/css">
    @page {
        size: A4 landscape;
    }
    body {
        writing-mode: tb-rl;
    }
</style>

Cannot add images from html.

Hello to all.

I have been trying to use this library to convert an html to pdf but unfortunately i cannot see any image get displayed from base64 or my local image.

I have tried from some base64 image ( small images ) and http/s images and it works fine.
But when I try from ImagePicker.Response.Data (Base64) or ImagePicker.Response.URI or ImagePicker.Reponse.filePath, it does not work.

I added a static image also but no success.
