Transformation problem in pptx to svg

[joyy]

Hi.

I am trying to convert pptx file in svg format. But I can get only text and boxes of pptx file not whole content in svg file.
So my svg file looks formerly black & white.

Here is my code:

File pptx = new File("pptxfile_path");
try {
PresentationMLPackage source = PresentationMLPackage.load(pptx);
Iterator partIterator = source.getParts().getParts().entrySet().iterator();
while (partIterator.hasNext()) {

Map.Entry pairs = (Map.Entry) partIterator.next();

Part p = (Part) pairs.getValue();
if (p instanceof SlidePart) {
ResolvedLayout rl = ((SlidePart) p).getResolvedLayout();

System.out.println(XmlUtils.marshaltoString(rl.getShapeTree(), false, true, Context.jcPML,
"http://schemas.openxmlformats.org/presentationml/2006/main", "spTree", GroupShape.class));

SvgExporter.svg(source, rl);
}
}
} catch (Docx4JException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}

and from SvgExporter.svg(source,rl) I get string svg(e.g. String svg = intermediate.toString("UTF-8");) to write svg file.

I don't know where I do mistake.
Please help me.

You probably aren't doing anything wrong; its just that so far, only text boxes and lines are implemented.

What other shapes / objects do you need? If it is just images, they could be added easily.

Hi,
Thanx for reply.

yes,
I want whole data images,shapes but I don't know how to add these in my svg files.
Can you please help me?

I want whole data images,shapes but I don't know how to add these in my svg files.

Images I understand, but "whole data .. shapes", I don't.

An easy next step would be to support images. All other shapes would be a significant amount of work.

OK. Thnx for reply,

Now How can I add Images in my svg file?

In SvgExporter.java
from SvgExporter.svg(presentationMLPackage, rl);

I can get only
String svg = intermediate.toString("UTF-8");

and it gives only text not images.

I'll add image support in the next day or so.

Image support added in http://dev.plutext.org/trac/docx4j/changeset/1179

To see SVG lines in your html output, don't forget to use .xhtml file extension.

cheers .. Jason

Hi.

Thnx for reply.

Now the new code is working fine for images.

But I have a problem, if the pptx file contains more than 2 slides then last slides data are override.

and the other thing is output .xhtml file contains text with red boxex.

I don't know what's goings wrong.

I am attaching the test case.pptx file and resulted testcase.xhtml files with this post.

Thnx in advance.

Great.

But I have a problem, if the pptx file contains more than 2 slides then last slides data are override.

SvgExporter.svg processes a single slide.

I've uploaded http://dev.plutext.org/docx4j/docx4j-ni ... 100731.jar which alters the API to make this more obvious. See http://dev.plutext.org/trac/docx4j/changeset/1180

Note that the RenderAsSvgInHtml sample doesn't attempt to process the slides in order - it really should be altered to do that I guess.

and the other thing is output .xhtml file contains text with red boxex.

The XSLT was putting those in, to make it easier to check the positioning of the box. With the above changeset, the box will only appear if log4j logging on SvgExporter is set to DEBUG level.

Hope this helps. .. Jason
