lijingrong / java-html2image Goto Github PK

What steps will reproduce the problem?
1. create a servlet on tomcat and a servlet use htmlimagegenerator
2. use html as below:

HtmlImageGenerator imageGenerator = new  HtmlImageGenerator();
imageGenerator.loadHtml(html);
return imageGenerator.getBufferedImage();
3.  the image generated has not utf 8 chars but contains [][][][] instead of 
arabic chars

What is the expected output?
arabic chars
What do you see instead?
[][][][][]

i think depends on tomcat setting, but i set tomcat to manage utf8
and as well request and response servlet are utf 8 set as follows:
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html; charset=UTF-8");


What version of the product are you using? 0.9 version

What steps will reproduce the problem?

HtmlImageGenerator imageGenerator = new HtmlImageGenerator();
imageGenerator.loadUrl("http://www.google.co.uk");
imageGenerator.saveAsImage("hello-world.png");

What is the expected output? What do you see instead?
The formatting is not correct at all, and the elements on google's start page 
are not where they should be. I have tried with a few web pages but none works 
as expected. 

What version of the product are you using? On what operating system?
0.9, Mac OS.

Please provide any additional information below.
There is also quite a few web pages where the tool throws an Exception (e.g. 
java.lang.RuntimeException: Unclosed "  )  Not sure why? If there is a problem 
with the HTML, it would be good if it could print the line number and 
information about what is wrong.

Hi,

it seems, that this project is a little bit orphaned, so some dependencies of 
HTML2Image changed during the last 5 years. 

So maybe you could replace the pom.xml with the one I've uploaded.
Despite of the fact that the springframework is now found at a different 
location in central maven repository I replaced 
org.xhtmlrenderer/core-renderer-library by flyingsaucer-core that delivers some 
improvements and bugfixes(e.g. rendering tables).

What do you think about?

I attached the html and converted code.

and the code is quite simple

@Test
    public void htmlToJpg() throws MalformedURLException{
        HtmlImageGenerator imageGenerator = new HtmlImageGenerator();
        String uri = new File("//home/gnsg/Desktop/test.html").toURL().toString();
        imageGenerator.loadUrl(uri);
        imageGenerator.saveAsImage("hello-world123.png");
//      imageGenerator.saveAsHtmlWithMap("hello-world.html", "hello-world.png");
    }

What steps will reproduce the problem?
1. convert the html to png 
2.
3.

So it looks like this project has essentially been abandoned - here's a tip for 
anyone else looking to use it to any great extent:

The size of the image will not be correctly regardless of whether you call the 
setSize method or not. Instead follow these steps:

1. do NOT call setSize - it makes no difference at all to picture size
2. The size should be set on the top level container in your HTML (e.g. set CSS 
width and height of top div).
3. This will make the image, on average, 1.322 scale of what you expected.
4. To solve this, simple multiply the width/height values by 0.7625f (this 
seems to be a sweet spot but you could make it more accurate still).

I use: int width = Math.round(origWidth*0.7625f); - and same again for height.

This should give you the correct height within around 3px on each axis for 
pictures less than 1024*768 in size.

Hope this helps someone, pity this library is no longer under development 
although looking at the code it uses a lot of weird tricks to force the HTML 
into an image format. 

Cheers,

Jack

What steps will reproduce the problem?
1. Create a <div> and inside that div, a <span> 
2. Make the <div> width:600px;
3. Make the <span> word-wrap:break-word; display:block;
4. Place WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW(and so on) into 
<span>

What is the expected output? What do you see instead?
In Firefox, IE and Chrome, the String gets wrapped into several lines if its 
length exceeds 600px.
Instead the word-wrap gets ignored.

What version of the product are you using? On what operating system?
Version 0.9 on Windows 7.

Hi,

it seems your Maven is down.

Could you please activate this again?

Thanks!

I was really hoping this would be a solution to my problem, as I wish to 
generate thumbnails for user generated HTML pages without creating a child 
process on my server. Thank you anyways for the work!

I think you need to update the maven repo in this project home page, the new 
one seems to be
      <url>http://repo.jfrog.org/artifactory/third-party-releases-local</url>

Is there a more current version or new repository for use with Maven?

Would be nice to have here information which version of Java is required, so 
that you don't need to test it.
