Or indent paragraphs... Hard to read otherwise.

Enhancement request:

It would be great if pdfkit could support an arc function like HTML5 Canvas.

From the canvas spec:

void arc(double x, double y, double radius, double startAngle, double endAngle, optional boolean anticlockwise);

Currently it doesn't appear possible to draw arcs using pdfkit....

Thanks!

I found the array of supported sizes in page.coffee. It would be nice if those pixel dimensions were posted in the documentation for quick reference.

Here is a temporary fix I am currently using.

list: (array, @x, @y) ->
    gap = Math.round (@_font.ascender / 1000 * @_fontSize) / 2

    for item in array
        @circle x + 3, @y + gap + 3, 3
        @text item, x + 15
        @y += 3
        @x -= 15
    @fill()

I'm trying to put some real transformation from a svg file created by illustrator, but the transform method doesn't work as it should be.

the file (test.js) has one line:

var PDFDocument = require ('pdfkit');

and it throws this error:

/mydir/node_modules/pdfkit/lib/document.coffee:1

It might be really convenient to have a roundRect function - like the ReportLabs pdf canvas has.

Of course if is possible to do find a workaround using lines and bezier curves at the corners. But a simpler helper function would be great..

I'd love to use pdfkit to read an existing PDF in, get a list of form fields (text fields), populate them with data and write a new document out.

Thanks.

I found that (accidentally!) setting lineWidth = -1 on PDFDocument before drawing shapes results in Adobe Reader not loading the PDF file.

Might be worth a gate to prevent other people accidentally doing the same thing ;-)

All the returns in PDFobject::convert could be removed for clarity, and, in fact, one branch (Dates) doesn't even use one.

PDFKit is a great tool that we want to see it even better.

Couple of things that might be worth looking into:

• Stamping external vector content - Lets say we have some logo in a vector format stored either in a PDF, PS or EPS file. It would be great if we can stamp it on a pre-defined location either on one or all pages so that the vector content can be included without rasterization.
• Backgrounds - It would be slim if we can define a one page external PDF that on its own can contain any type of content (vector, images, text) that could be even produced in a 3-rd party app such as AI and used as a background for the PDF generated from PDFKit. A lot of PDF documents have the same layout and design for all pages so it would be a lot easier if we can just apply the dynamic content on a predefined section of the page (page minus header and footer for example) and pull the background from a pre-existing PDF design.

I am not sure if these are already in but I would like to mentioned them anyway:

• The ability to define regions or boxes to populate with content and place them on one or all pages at a certain location. In that context a special case would be headers and footers that would even contain calculated values such as page numbers.
• A clear way to mark a page break within the HTML.

Example for this:

var coffee  = require('coffee-script'),
pdfkit  = require('pdfkit'),
pdfdoc = new pdfkit;

pdfdoc.rotate(90, {origin:[20,20]})
pdfdoc.text('hi',20,20)

pdfdoc.write('test.pdf');

But if instead of 90 we use 90.0001, it works(90.00001 or smaller doesn't work). Same thing goes for 270 degrees.

PDFDocument.text appears to throw an exception when passed a number to draw, instead of a string, e.g., document.text(23, 10, 10);

It might be nicer to call toString() on the first argument?

When I set the align option to justify on an embedded TTF font, the text will still be left aligned. I have tried with three different fonts, but this one will probably be good enough for testing.

Sorry I haven't investigated the problem further before posting this issue.

Is there any way to do this? For example we have made 3 pages, we write something on the 3rd page, and then write something else on the 2nd.

Perhaps a simple HTML parser as well?

when i try to do this

doc.text('?') it gives the following error:

/Users/NeCkEr/.node_libraries/.npm/pdfkit/0.1.5/package/lib/mixins/text.coffee:178
wrap.extraSpace = (options.wordSpacing || 0) * (words.length - 1) + (opt
^
TypeError: Cannot read property 'length' of null

Can you provide some documentation that how does it work for developers? Actually on the part converting javascript objects to pdf. I found it confusing.

Thanks

in my case, Korean lanuage.
I write simple test for converting text.
English is ok. but Korean is not...
if you need fonts, I will send Korean fonts to you.

Opening the example PDF document at http://devongovett.github.com/pdfkit/example.pdf in Adobe Reader 10.1.0 and scrolling down to the fourth page, Adobe Reader displays the error message "Cannot extract the embedded font 'Chalkboard'. Some characters may not display or print correctly".

I uploaded a couple of screenshots to: http://imgur.com/a/7ZomJ

Is there support for utf8?
I will try do:

doc.text('Бла бла бла', 0, 0);
doc.write('test.pdf');

in the resulting document, I see it => ;0 1;0 1;0

Difficult problem to understand and to explain.
When I write the text "une forêt" the pdf has "une fforêt" (2 f).
After hours looking for the problem, I discovered that my f was encoded "" on class Subset. String.fromCharCode(@unicodes['f']) === ""
On mixin "text" function _escape replace \ by \ ... I don't know /understand why but removing this replace fix my problem and I have no time to investigate deeper..

down in loca.coffee and other files there's

Data = require '../../Data'

but this doesn't seem to be the right path... shouldn't it be ../data ? causes a failure on requiring pdfkit itself...

Also, page margins.

node v0.6.1
pdfkit v0.1.6

Code:

var pdf = require('pdfkit');

Hi!

Currently I am using PDFKit and i have a good results.
So, I'm trying to find something about how to change the page orientation of the document. Can you help me? some tip ?

I `m working with ruby on rails

thanks for attention

Is there a way to have text in a left column (pane) that controls what is visible on the right? I'd like to be able to click on something on the left and have the visibility of images on the right change. Even more specifically, I'd like to have images overlayed and control which overlays are present. The overlays would ideally be any pdf content, but could be limited to PNGs.

Can these features be implemented in pdfkit, and if not, are they possible at all in the PDF format?

Also, does every PDF reader, such as those on the mobile devices iPhone and Android support such interactivity?

I'm sorry to ask so many questions, but I've googled PDF for hours and I can't really figure out what is possible.

When I use cmyk color values ( e.g. .strokeColor([0,0,0,100]), the PDF is created successfully, but is not readable by any PDF viewer, even if I only use CMYK colors. CMYK colors were introduced by this commit: 6a9d2f8

I think there has to be a document-wide property that defines the correct color space (something like DeviceCMYK).

The document.write function should allow a callback function to be passed through to fs.writeFile.

Otherwise one doesn't know when the file has actually been written..

Nice library!

As the current version (0.1.5), it is able to put asian (zh-tw in my case) language characters in a text, with proper (not default) font file supplied. That is really good!

Unfortunately the texts cannot be correctly wrapped. So the paragraph will display in a single line and go right all the way outside the page boundary. If we five paragraphs, for example, then there will be five lines of text. No matter how many characters each paragraph have.

I think it is a little bit difficult to very correctly wrap Chinese texts. But I guess there might be some work around not too difficult.

In Javascript, not coffee:

PDFDocument = require('pdfkit');
doc = new PDFDocument();

        // register and use a font, set the font size, and render some text
        doc.registerFont('hn', __dirname + '/public/fonts/HelveticaNeue.ttf');
        doc.registerFont('hnl', __dirname + '/public/fonts/HelveticaNeueLt.ttf');
        doc.font('hn')
           .fontSize(25)
           .text('Some text with an embedded font!', 100, 100);

        // Add another page
        doc.addPage()
           .fontSize(25)
           .text('Here is some vector graphics...', 100, 100);

        // Write the PDF file to disk
        doc.write('output.pdf');

Where's the problem?

When using the window side by side with another the text it truncated because the website doesn't allow wrapping when the main can't be 800px. Just commenting that out makes the page more readable. 1/2 of a HD 1920 px screen is 960 and with your 250px sidebar I need at least 1050 to read the page.

There is a bug where pdfkit doubles a character.

For example, if I write:

doc.text("Tel (787) 760-3000");

I get different results:

Tel (787))760-3000

or

Tel (787) 760--3000

or

Tel (787) 760-300000

I haven't been able to pinpoint how to fix this. But I found that if I write a dash before the one in between the numbers:

doc.text("Tel - (787) 760-3000");

It doesn't double the dashes, it doubles the parenthesis.

Very confusing. Thanks!

From line 33 of Reference.coffee:

data = @stream.join '\n'
if @stream

...

This throws an exception if stream is null. Swapping the lines fixes the bug:

    if @stream
        data = @stream.join '\n'

Here is the error message that I get when I use Passenger to run my Ruby on Rails app and try to create a PDF page. I am using PDFKit Middleware.

wkhtmltopdf runs fine on the command line, and it also runs fine when I launch my Rails app using script/server.

Please help - PDFKit is amazing - thanks for your work on it!

Found a bug, don't know if the future update will fix it, but if you have an abbreviation, e.g. R.E.B.E.L.S., and it's on the of a line it separates the abbreviation instead of leaving it all together, e.g. R.E.B. \n E.L. .

Did the example make sense?

Thanks!
