Can I help with this? What would be involved?

I am running cef-pdf from within a Linux container and would like executions to pipe file input into the container. This would enable a common pattern of running containers and destroying them afterwards so I could run omething like:

$ cat some-file.html | docker run --rm -it --env DISPLAY=172.17.0.2:99 \
	 my-cef-image cef-pdf \
	--backgrounds

I see this as an alternative to --file and --server options. That way I can run cef-pdf without having to save the input to disk or retrieve it from a URL.

Hi,
I wrap your application into my app and I get this error:

[1113/143014.498002:ERROR:icu_util.cc(137)] icudtl.dat not found in bundle
[1113/143014.498081:ERROR:icu_util.cc(173)] Invalid file descriptor to ICU data received.
Trace/BPT trap: 5

Every file should be present, I copy whole folder into my app. Not sure, I can do it as I do - so that in my .app I use your .app. Do you have idea, where could a problem?

Did you see it before?

Could you add a render to png feature ?
So I can render HTML/SVG to png ?

I've been doing this in a C# application, but all that CefGlue doesn't work right on all platforms...
One way to get the image is in the OnPaint sub of CefRenderHandler.

internal class DemoCefRenderHandler: CefRenderHandler
protected override void OnPaint

Example
https://github.com/ststeiger/CefGlue_NetStandard/blob/master/PdfGlue/Demo/DemoCefRenderHandler.cs

curl -X POST http://localhost:9288/timeout.pdf --header "Content-Location: http://www.google.com" > output.pdf

works on 0.3.1 but hangs forever on 0.3.2 and master

Same error with both ninja and unix makefiles.
Trying to compile on Ubuntu 16.04.01
Build outputs attached

Load end may never occur its important to clean up when connection is closed.

When uploading an HTML string that contains an image with a large base64 encoded source, cef-pdf --server crashes with exit code 139.
This branch https://github.com/efx/cef-pdf/blob/topic-memory-bug/Dockerfile has the debian stable release Dockerfile that shows the Linux environment I am testing with. I am compiling with http://opensource.spotify.com/cefbuilds/cef_binary_3.3112.1652.g8c8deea_linux64.tar.bz2.

reproduction

I wrote a script in node.js to upload. I tried getting curl to work but was unable to:

1. start the cef-pdf in server mode cef-pdf --server --port=8000
2. clone https://github.com/efx/bug-test.git. It assumes you have node.js installed. If you don't you can quickly install to your home directory on a *nix like system with https://github.com/creationix/nvm/blob/master/README.md#install-script
3. cd bug-test && npm install && npm start

I tested this against a build I compiled from master on MacOS and saw the CPU max out and 100% for the cef-pdf process until I closed it.

Thanks for building this tool. It looks much more promising and reliable than other html to pdf binaries/libraries I have worked with.
I have been using it successfully so far but accidentally typed:

 $ src/Release/cef-pdf.app/Contents/MacOS/cef-pdf --file ./test.html ./test.pdf

Instead of erroring, the binary unexpectedly overwrite test.html. It would be nice if the cli threw an error that I mistyped the --file switch, or was a tad more flexible.

I would be deeply grateful for a release including the remote-trigger feature. The current release does not include this feature which is absolutely necessary for our use case.

is it possible to increase the runtime verbosity when the PDF generation occurs? I think this would be helpful for troubleshooting complex pages being generated. If it is relatively simple, I can help contribute documentation for it.

I am trying to compile cef-pdf within a container based on debian jessie. It fails at the configure step:

CMake Error at src/CMakeLists.txt:14 (list):
  list does not recognize sub-command FILTER

Does CMakeLists.txt need updated for this version of cmake? Or is this another issue?

One approach would be to add a command line option which takes a javascript expression which returns a boolean. This expression would be repeatedly evaluated until it returns true at which point the PDF would be generated.

I'd love to help make this a thing and will be investigating how to do it now. Any help or guidance through the source would be very appreciated.

I can recall having managed it in the past.

Following the current building instructions, I downloaded the correct CEF distribution files for my system, cd'd into a temp directory, then ran this command I constructed based on the instructions:

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release \
    -DCEF_ROOT=~/dl/cef_binary_3.3282.1726.gc8368c8_linux64/Release \
    ~/src/cef-pdf

It failed for me with this:

CMake Error at CMakeLists.txt:192 (find_package):
  By not providing "FindCEF.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CEF", but
  CMake did not find one.

  Could not find a package configuration file provided by "CEF" with any of
  the following names:

    CEFConfig.cmake
    cef-config.cmake

  Add the installation prefix of "CEF" to CMAKE_PREFIX_PATH or set "CEF_DIR"
  to a directory containing one of the above files.  If "CEF" provides a
  separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!
See also "/home/anko/src/cef-pdf/build/CMakeFiles/CMakeOutput.log".

This is the first time I touch cmake, so I'm probably just dumb. What did I do wrong?

Relatedly, could the build be adapted to only 1 step? It would help automate testing and packaging.

It seems reasonable that pages which intend to trigger pdf generation are able to register their intent to do so within a given timeframe potentially even syncronously on PageLoad. I will investigage this.

workaround is to install libxss1 libgconf-2-4 and libstdc++6 but i'm hoping there is some way to link these statically.

I am compiling v0.3.4 (4247a7b) from within a debian stretch based Linux container.
here is the trimmed output where the errors occur:

any ideas?

I had to struggle, as I do not know cmake and not to much about C++ to compile.
You can do it different, but his is just a hint how I got it working.

Treet structure I use:

C:\source\repros\cef-pdf
├───asio
├───cef
│ ├───cmake
│ ├───Debug
│ ├───include
│ ├───libcef_dll
│ ├───Release
│ ├───Resources

Build I do will be x64 & release

Steps:

1. you ned Cmake
2. Lets say you use C:\source\repros for git download and compiling.
3. open command prompt or use a Windows Git client, then call:

cd /d c:\source\repros
git clone --recursive https://github.com/spajak/cef-pdf

4. download CEF binary for windows from: CEF Binaries with Webbrowser, select x64 version
   (I used cef_binary_73.1.13+g6e3c989+chromium-73.0.3683.75_windows64.tar.bz2)
5. extract files of CEF to cef-pdf directory in subdirectory cef
   (release, cmake etc. directores must be directly placed in c:\source\repos\cef-pdf\cef\
6. open VS Developer prompt, now we use cmd-prompt to continue
7. go to cef-pdf source

cd /d c:\source\repros\cef-pdf

8. Make directory VS2019

mkdir VS2019

9. go to subdirectory CEF

cd cef

10. make directory VS2019

mkdir VS2019

11. change to directory VS2019

cd VS2019

12. run cmake:

cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release ../

13. If successfully, change directory to cef-pdf\VS2019

cd ....\VS2019

14. run cmake:

cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT=C:/Source/cef-pdf/cef ../

15. should run trough
16. open c:\source\repos\cef-pdf\VS2019\cef-pdf.sln in VS2019
17. now compile and find allot of errors.

18. go troug all files that VS claims as errors and add a semicolon at the end, example:
    IMPLEMENT_REFCOUNTING(XYZ)
    to
    IMPLEMENT_REFCOUNTING(XYZ);
19. Add missing parameter for OnProcessMessageReceived
    bool OnProcessMessageReceived(CefRefPtr<CefBrowser> browser, CefProcessId source_process, CefRefPtr<CefProcessMessage> message) OVERRIDE
    to
    bool OnProcessMessageReceived(CefRefPtr<CefBrowser> browser, CefRefPtr<CefFrame> frame, //Newly added CefProcessId source_process, CefRefPtr<CefProcessMessage> message) OVERRIDE
20. Compile and hope ist sucessful now :)

Hope this helps, for pplz that donot use C++ usually

the build appears to succeed but then the machines running the program fail with the error

./cef-pdf/linux/linux/Release/cef-pdf: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./cef-pdf/linux/linux/Release/cef-pdf)

the builds provided on the release page do not do this.

Hi I have tried cef-pdf (cef-pdf.0.3.2.win64) in my pc windows 10. but the execution fail with

Thanks

Not sure if this actually has any negative effects?

its obviously not being passed through, i'll look into this.

As a user, I would like the ability to customize the PDF metadata. (Creator and Producer specifically) Right now it lists the cef user agent and underlying skia/PDF library as the content creator.

I run build command in macos

cmake -G "Xcode" -DPROJECT_ARCH="x86_64" -DCEF_ROOT=/Users/123/src/cef-pdf/cef_binary_90.6.7+g19ba721+chromium-90.0.4430.212_macosx64_minimal ../

or

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT=/Users/123/src/cef-pdf/cef_binary_90.6.7+g19ba721+chromium-90.0.4430.212_macosx64_minimal ../

It failed with this:
