Relative URL to images

[pritesh.shah17]

Hello All,

I am converting HTML to doc.
There are images in HTML which have relative URL.
Due to relative URL, generated doc doesn't display the image.
Can you anyone tell me how resolve relative URL, so doc to display images?
Also, when user is not connected to internet, images with full or absolute urls are not displayed. can you anyone help me solve this issues?

Thanks in advance!!!

Thanks,
Pritesh

What Java code are using using to do your conversion?

Relative URLs work for me using:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

public static List<Object> convert(URL url, WordprocessingMLPackage wordMLPackage)

What does your relative URL look like?

Also, when user is not connected to internet, images with full or absolute urls are not displayed. can you anyone help me solve this issues?

You mean, in your Word document? Try converting your linked images to embedded ones. See the ImageConvertEmbeddedToLinked sample which goes the other way.

ps this topic will be moved to the appropriate subforum soon

Thanks Jason for reply.

Please find attached sample code using which I am trying to convert html string to doc.
Html string have "<img src=" pointing to live url of image. Image is added to generated doc but displayed only when I am connected to internet. So Its linked image and I want it to embed it to document, so even if I am not connected to internet, I see images in my doc file.

Again, highlighting I am converting Html string to doc.

Also, you can check the html file opening browser and document. Formatting and look & feel are much different.

Looking forward for you help to resolve my issue.

Thank You very much for reply and thanks in advance for further help

Thanks,
Pritesh

Your code uses AltChunkType.Html, and then invokes convertAltChunks:

But docx4j won't process that. It only processes XHTML and text/plain (unless you have MergeDocx, in which case it also does docx/dotx etc).

So what you are seeing (conversion quality, linked images) is a conversion done by Word.

I suggest you convert your HTML to well formed XML (using JTidy or something), and then use docx4j's XHTMLImporter directly. See the ConvertInXHTML* samples.

Thanks for quick reply Jason.

So according to you, If I convert html to xHtml and the use XHTMLImporter to convert it to doc, images would be embedded instead of linked, then I see images in doc even if I am not connected to Internet.

Please let me know if my understanding is not correct

Looking forward for you reply.

Thanks,
Pritesh

Correct

Hello Jason,

Thank you very much for continuous support in resolving my issue.

I tried converting my html to xhtml using Jtidy and then used xHTMLImporter for converting generated xhtml to doc. Doc is generated successfully and I am able to see the image without internet also, but the formatting of bullets points are very bad.

Please see the attached code, xhtml, and generated doc in zip file.

Please help me to resolve this formatting issue.

Thanks in advance!!

Thanks,
Pritesh

Also, Jason, How can i add header and footer to all the pages when I am converting xHTML to doc using xHTMLImporter?

Please help!!!

Hello Jason,

Please reply,
I deadly need your help

Thanks,

Please create new topics, one for each of the two new questions, in the correct sub-forum.

But first, search to see whether they have been raised/answered before. I'm pretty sure bullets have come up before, and the other may have.
