imgkit's Issues

wkhtmltoimage --load-error-handling option incorrect handling

I think I spotted an issue that prevents the option wkhtmltoimage --load-error-handling to be properly handled by imgkit.

The issue happens here https://github.com/jarrekk/imgkit/blob/master/imgkit/imgkit.py#L239

    if 'Error' in stderr:
        raise IOError('wkhtmltoimage reported an error:\n' + stderr)

Running the last version of wkhtmltoimage (which disables local files loading by default) I see

~$ wkhtmltoimage index.html test.jpg
Loading page (1/2)
Error: Failed loading page file:///home/angelo/index.html (sometimes it will work just to ignore this error with --load-error-handling ignore)
Exit with code 1, due to unknown error.

~$ wkhtmltoimage --load-error-handling ignore index.html test.jpg
Loading page (1/2)
Warning: Failed loading page file:///home/angelo/index.html (ignored)
Rendering (2/2)
Done

>>> options['load-error-handling'] = 'ignore'
>>> imgkit.from_string(html, 'foobar.jpg', options = options)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/imgkit/api.py", line 90, in from_string
    return rtn.to_img(output_path)
  File "/usr/local/lib/python3.6/dist-packages/imgkit/imgkit.py", line 240, in to_img
    raise IOError('wkhtmltoimage reported an error:\n' + stderr)
OSError: wkhtmltoimage reported an error:
Loading page (1/2)
Warning: Blocked access to file
Error: Failed to load about:blank, with network status code 301 and http status code 0 - Protocol "about" is unknown
Rendering (2/2)
Done
Exit with code 1 due to network error: ProtocolUnknownError

As you can see imgkit detects the Error string in stderr and raises IOError. This is not correct and line 239 should be modified to something like this (abort is the default option while the other ones are ignore and skip)

    load_error_handling_option = self.options.get('--load-error-handling', 'abort')
    if 'Error' in stderr and load_error_handling_option in ('abort', ):
        raise IOError('wkhtmltoimage reported an error:\n' + stderr)

OSError: wkhtmltoimage exited with non-zero code 1. error: Unknown long argument --orientation

Im using code from example

body = """
<html>
  <head>
    <meta name="imgkit-format" content="png"/>
    <meta name="imgkit-orientation" content="Landscape"/>
  </head>
  Hello World!
  </html>
"""
	imgkit.from_string(body,'name.jpg')

and i get error:

OSError: wkhtmltoimage exited with non-zero code 1. error:
Unknown long argument --orientation

How to set the DPI of output image?

My code is as follows:
options = {
"quiet": "",
"width": 460,
"dpi": 120,
}
imgkit.from_file("render.html", 'out.jpg', options=options)
But after I run it, PyCharm display：
Unknown long argument --dpi

Encoding character bug in .from_string

When using .from_string function, characters like °,Ç,ã, etc, has encoding bugs

Reproducing
My html string looks like this: "objeto aguardando retirada no endereço indicado Para retirá-lo, é preciso informar o código do objeto".

So i created this code for testing:

Outputs:

-With .from_file:

-With .from_string:

FileNotFoundError: [Errno 2] No such file or directory: 'which'

Hey there,

first of all, sorry to be bothering you.
I have a very simple python function which takes an HTML table and converts it to an img:

import imgkit

def create_image_from_html(html):
    config = imgkit.config(wkhtmltoimage='/usr/bin/wkhtmltoimage')
    options ={
        "crop-w": "550",
        "xvfb": ""
    }
    imgkit.from_string(html, "portfolio.jpg", options=options, css="table.css", config=config)
    return "portfolio.jpg"

It used to run fine, but suddenly it somehow stopped working (Ubuntu Server 20.0.4, Flask with uWSGI). I already uninstalled and installed it from the binary. I also installed xvbf, just in case.

But I still run into the following error:

Traceback (most recent call last):
  File "/usr/lib/python3.8/threading.py", line 932, in _bootstrap_inner

    config = imgkit.config(wkhtmltoimage='/usr/bin/wkhtmltoimage')
  File "/home/jan/Slackbot/env/lib/python3.8/site-packages/imgkit/api.py", line 101, in config
    return Config(**kwargs)
  File "/home/jan/Slackbot/env/lib/python3.8/site-packages/imgkit/config.py", line 26, in __init__
    self.xvfb = subprocess.Popen(['which', 'xvfb-run'],

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'which'

I have confirmed that wkhtmltoimage exists in /usr/bin/, I can see it with ls.
Any idea what could be causing this?

Thank you very much in advance!

Lines 15-27 in config.py have an issue, due to the lack of an stderr argument, it ALWAYS prints the stderr to console. This, for me, printed the message INFO: Could not find files for the given pattern(s). Adding stderr=subprocess.DEVNULL to each subprocess.Popen fixed it.

Zooming in

Is there anyway to zoom up in a webpage? Like to 125% instead of 100%
Also if my webpage isnt fully loaded, what do you reccomend I do.

Not loading the ajax generated results

Hi there,
I am using imgkit to save my page with charts. I am using from_url function. It saves the page as jpg without any problem however the content that are loaded using ajax are not in the saved image. Is there a way I can add delays on the image creation process so that it will include the ajax results as well?

Thank you,

What is img = imgkit.from_url('http://google.com', False) return object

Hi, can I convert the return bytes into a base64 string?
I am using like this wont work:

img = imgkit.from_string(html, False, options=options)
        img_byte = base64.b64encode(img)
        img_str = str(img_byte.decode('utf-8')).replace('\n', '')
        print(img_str)

from_string doesn't look at options for encoding?

Hi there! Thanks for sharing this project! It has been very helpful.

Imgkit works very well for the majority of cases. My issue lies when I send it characters that are greater than 0x7f, which I would like to be interpreted using latin-1.

To indicate I would like to use latin-1, I've passed options with encoding set to latin-1 to my from_string function call: imgkit.from_string(htmlString, output.png, options={'encoding':'latin-1'})

I'm getting an UnicodeDecodeError on line 220 of imgkit.py. Looking at the code, it appears to be forcing utf-8.

Perhaps "from_string" does not use options? Is there something else I'm doing wrong?

Thanks in advance!

Error when calling imgkit

While using this method
imgkit.from_file('test.html', 'out.jpg')
imgkit doesn't seem to be able to work with a file name that doesnt contain an extension
imgkit.from_file('test.html', 'out')
is there any work around for this ?

Exporting image to a variable can include internal warnings from miscellanous components, producing an invalid output.

Basically, I'm using the code as following:

	options = {
		"xvfb"   : "",
		'format' : 'png',
	}

	img = imgkit.from_string(rendered_html, False, options=options)
	print("Image generated")

	with open("test.png", "wb") as fp:
		fp.write(img)

	buf = io.BytesIO(img)
	im = Image.open(buf)
	im.save("figure.png")

	buf.close()

PIL fails to open the bytes array with OSError: cannot identify image file <_io.BytesIO object at 0x7fde9c07d888>. Saving the image, Irfanview can open the file, but other viewers report it as invalid.

Opening the image in a hex editor yields:

It looks like the stdout of something internal (wkhtmltopdf?) is getting captured into the "image" output, somehow.

Can we please add release notes to releases, so that we can know whats are new updates and bug fixes.

Images not exactly the same as HTMLs?

Hello, I am wondering why some output images are not exactly the same as the HTMLs that I opened in the browser?

I tried to include disable-smart-shrinking in the options, but it seems not working.

Appreciate any help!

xvfb-run failed to start

After using this package, I have run into an issue with the invocation of xvfb-run under the hood. Each virtual headless server xvfb-run spins up will have spin down time. My script calls imgkit synchronously with repetitious invocations of the xvfb-run. The default server it tries is always the same (:99) of which each new one tries this server and fails as the process is still open in memory. A sleep of 100MS has been the work around.

The solution would be to tell xvfb-run with the option -a, --auto-servernum Try to get a free server number, starting at 99, or the argument to --server-num.

Is there a way currently to pass this option down from imgkit to the xvfb-run process being called?

If not, I will submit a PR of this possibility.

self.xvfb = subprocess.Popen(['which', 'xvfb-run'],stdout=subprocess.PIPE, stderr=subprocess.STDOUT,stdin=subprocess.DEVNULL).communicate()[0].strip()

我不知道为什么会产生这样的原因，但是我这样修改就可以正常使用了

Is there a custom image size option?

it converts to image file just fine but the width is fixed to 1024 px and I could not find a way to change it.
cropping won't work for me because I need a wider screenshot so I am wondering if there is a way to change the image size.

Instead of saving it to a file, could I get the bytes instead?

It would be more helpful if I didn't have to save it everytime I generate the image from html.

imgkit with xvfb renders blank images in output file

hi!
I am using a raspberry 3 B+ running Stretch Version 9.

I developed a python program using imgkit. I have html files in a local directory and I am trying to output them in jpg files.
When I launch my program manually from the terminal, my program works perfectly fine: my html files (that contains text and jpg files) are rendered with the correct css and saved as a jpg file with this message:

Loading page (1/2)
Rendering (2/2)
Done

But when I tried the first time to launch my script with systemctl start name.service , I got an error message telling me

QXcbConnection: Could not connect to display
You need to install xvfb(sudo apt-get install xvfb, then add option: {"xvfb": ""}

I followed the instructions, restarted my service, the program launched without the previous error. This is where the problem happens: when I looked at the output files, the css is correct, the text also, but all my images are blank.
I also have this error poping into my terminal:

libEGL warning: DRI2: failed to create any config
libEGL warning: DRI2: failed to create any config
Loading page (1/2)

After looking all around the web, I can't find anything close to an answer. Do you have any idea of what to do?
Thank you 🌻

Poor Rendering Quality / Poor Image Quality

The image quality, even when set to max, isn't very good. Is there a way to improve this?

Link to wkhtmltopdf's manual is broken

On README.md the link that points to wkhtmltopdf's manual returns as invalid page.

To solve my questions I used this link: https://wkhtmltopdf.org/usage/wkhtmltopdf.txt

ImgKit takes a long time to convert an html file to a jpg file (3 minutes)

imgkit.from_file(html_filename, image_filename, options={"width": 660, "disable-smart-width": ""})
is what I ran, and for some reason, at most times, this will take 3 minutes to run, and just yesterday, and only for yesterday, was it running at around 3 to 10 secs. The html, I am trying to render, is not important to mention, as the same problem happens with "www.google.com", about 3 minutes as well. I am running on Ubuntu 20.04.

Extra Detail:
for most of the time, there is no output in the console, and only in the last few seconds, the output appears

Loading page (1/2)

from_string() got an unexpected keyword argument 'config'

I have two issues to report. One is a product of the other.

My code for the first one is as follows:

wkhtmltoimage_binaries = imgkit.config(wkhtmltoimage = '/app/bin/wkhtmltoimage')
img = imgkit.from_string('<body>hi</body>', False, config = wkhtmltoimage_binaries)

The resulting error is as follows:

TypeError: from_string() got an unexpected keyword argument 'config'

This confused me, as it has worked for a long time until just recently. Your readme file also mentions config being a keyword argument. Nevertheless, I edited my code to the following in hopes that it might detect the binaries automatically:

img = imgkit.from_string('<body>hi</body>', False)

It did not detect them automatically. In fact, the new error seems to communicate the presence of a bug. The error is as follows:

OSError: No wkhtmltoimage executable found: "command not found"

So I have two questions:

Are we no longer able to configure imgkit to where we can specify the location of the wkhtmltoimage binaries?
Following No wkhtmltoimage executable found:, isn't it meant to display the directory that it attempted to read from, rather than "command not found"?

OS: Ubuntu 20.04.2 LTS (Focal Fossa)

ImgKit does not render images in local file

Hi,

I am trying to convert a local HTML file into a jpeg. Everything works, except for the image in the HTML document, which doesn't show up. I've tried everything, including setting the img src to base64. The image still doesn't show up in the final jpeg.

I also read somewhere that I should add a header to my document to make it work, but it doesn't help.

UnicodeDecodeError on using "quiet" option

This works fine.

img = imgkit.from_string(data.to_html(), False, options = {'width': 772, 'disable-smart-width': '', 'zoom' : 1.5})

This is the output.

Loading page (1/2)
Rendering (2/2)

But if I add the "quiet" option to suppress output, it does not work.

img = imgkit.from_string(data.to_html(), False, options = {'width': 772, 'disable-smart-width': '', 'zoom' : 1.5, 'quiet': ''})

This is the error:

This is data.to_html(), if it helps.

If I remove False argument and save the image as a png file instead, it works.

老哥，你这个README是抄的Python-PDFKit项目的readme吗？

You can pass a list with multiple URLs or files:

imgkit.from_url(['google.com', 'yandex.ru', 'engadget.com'], 'out.jpg')
imgkit.from_file(['file1.html', 'file2.html'], 'out.jpg')

Python-PDFKit可以这样用，你这个转图片不支持这样用啊！

I've been able to get it working with my local macOS environment without using xvfb, but once I try in an AlpineLinux environment that requires xvfb I get this error. I can reproduce the error with my local environment by using the xvfb flag there.

on macos | Error: No available formula with the name "wkhtmltopdf"

when i try brew install wkhtmltopdf i get this:

`
Error: No available formula with the name "wkhtmltopdf"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.

anyone can help?
