Hi Team,
The requirement is extracting the images and saved into new document.For the extraction process using paragraph node and fig caption as keyword. In my code i have separate the image handling in following ways
Section A-handling figures with caption as previous
Section B-handling images with caption as nextsibling
Section C-handling images inside the table
Section D-handling images landscape mode
The input document having images below label is there instead of fig caption.because in my cases handle fig caption fine but label section is not handled.
So please kindly help me to extract the labeled images along with label tag.(fig1 & fig 9)
The input Test.zip (2.7 MB)
The source code source.zip (8.3 KB)
The expected output expected output.zip (2.2 MB)
The actual output ActualOuput.zip (2.2 MB)
Thank you very much,
pria

Thanks for your inquiry. Please note your code of your described sections does not cover the Figure 1 and Figure 9 scenario. Please check document structure(DOM) in document explorer, it will help you to work with Word documents and refine your code. The code stops collecting nodes when it finds a Paragraph node without Shape child node. In this scenario you need to bookmark the contents and extract these nodes as suggested in other post.
Hi @tilal.ahmad,
Thanks for your feedback,
I had tried that one it shows the index error and also I had discussed about that issue.
how can i check shape child node of paragraph node.please help me to resolve it.
Regards,
pria.
@akshayapria
You are already checking the Shape child nodes count of a paragraph in your above shared code.
....
Node previousPara = paragraph.getPreviousSibling();
while (previousPara != null && previousPara.getNodeType() == NodeType.PARAGRAPH
//&& previousPara.toString(SaveFormat.TEXT).trim().length() == 0
&& ((Paragraph) previousPara).getChildNodes(NodeType.SHAPE, true).getCount() > 0) {
if (previousPara != null)
nodes.add(previousPara);
previousPara = previousPara.getPreviousSibling();
}
...
Please share your sample code here. We will look into it and will guide you accordingly.
Hi @tilal.ahmad,
Thank you very much.
The source code is source.zip (8.3 KB)
I had shared the input document,expected output,actual output
please help me to resolve the same .

@akshayapria
I think there is some confusion, you have again shared your old code. Please share the code you are using to apply above shared bookmark approach.
Hi @tilai,
Please made the changes in that new extraction code.
please help me to solve the issue the showcase nearing .so please kindly help me
The sample code is Test.zip (41.0 KB)
Thanks in advance,
pria
@akshayapria
Thanks for your feedback. Please check sample code snippet to bookmark the contents and extract them in your other post. You can customize it as per your document, it will help you to accomplish the task.
Hi @tilal.ahmad
Thanks for your feedback.
please,I have enclosed the code for labeled images.
but in some cases it is not working.please kindly help me to change the conditions .The source code is,
interimdoc.updateListLabels();
DSMT4(interim);
NodeCollection shapes1 = interimdoc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable)shapes1)
{
if (shape.hasChart() || shape.hasImage())
{
Paragraph paragraph = shape.getParentParagraph();
// Modify this condition according to your requirement
if (paragraph.toString(com.aspose.words.SaveFormat.TEXT).contains("a)")
|| paragraph.toString(com.aspose.words.SaveFormat.TEXT).contains("b)")
|| paragraph.toString(com.aspose.words.SaveFormat.TEXT).contains("c)"))
{
com.aspose.words.Document dstDoc = new com.aspose.words.Document();
NodeImporter importer = new NodeImporter(interimdoc, dstDoc,
ImportFormatMode.KEEP_SOURCE_FORMATTING);
Node newNode = importer.importNode(paragraph, true);
dstDoc.getFirstSection().getBody().appendChild(newNode);
String Imgcaption = (String)shape.getParentParagraph().getNextSibling()
.toString(com.aspose.words.SaveFormat.TEXT);
//

run1.getFont().setColor(Color.RED);
p.getRuns().add(run1);
p.appendChild(new BookmarkEnd(interimdoc, "MyBookmark"));
dstDoc.save(filename);
i++;
}
Node node = shape.getParentParagraph().getNextSibling();
// Modify this condition according to your requirement

NodeImporter importer = new NodeImporter(interimdoc, dstDoc,
ImportFormatMode.KEEP_SOURCE_FORMATTING);
Node newNode = importer.importNode(shape, true);
dstDoc.getFirstSection().getBody().getFirstParagraph().appendChild(newNode);
// dstDoc.
/** OUTPUT FILENAME START **/
if (dstDoc.getFirstSection().getBody().getFirstParagraph().toString(SaveFormat.TEXT).trim()

@akshayapria,
Thanks for your inquiry. We are working over this query and will get back to you soon.
@akshayapria,
Thanks for your patience. Please use the following code example to get the desired output. We have attached the output documents with this post for your kind reference. output documents.zip (2.2 MB)

Hi team,
Thank you very much.
Its really useful for me.
Now , I need to bookmark the extracted images and also apply style to that images.
I have attached the source code for my extraction process.please help me to how to made changes in my code for bookmarking and apply stylename to that bookmarked content.
source code Kite.zip (16.9 KB)
The sample document Sample_Doc_input.zip (1.7 MB)
The expected output Sample_Doc.zip (33.7 KB)
Thanks & Regards,

@akshayapria,
Thanks for your inquiry. In this case, you need to move the cursor to the desired location and insert the text e.g. <fig>num_figure_5</fig>. Please refer to the following articles.

Moving the Cursor
Inserting a String of Text
Hi @tahir.manzoor,
Thanks for your feedback.
I have bookmark the place.
please,help me to add style in that bookmarked place.
((Paragraph) paragraph).getChildNodes(NodeType.SHAPE, true).clear();
Paragraph p = ((Paragraph) paragraph);
p.getChildNodes(NodeType.SHAPE, true).clear();
p.appendChild(new BookmarkStart(interimdoc, "MyBookmark"));
Run run = new Run(interimdoc, "<Fig>Numbered_Figure</Fig>");
run.getFont().setColor(Color.RED);
p.getRuns().add(run);
p.appendChild(new BookmarkEnd(interimdoc, "MyBookmark"));
Thanks & regards,
pria.
@akshayapria,
You are setting the bookmarkâs text color correctly. Could you please share some more detail about your requirement along with expected output document? We will then provide you more information on this.
Hi @tahir.manzoor,
Thanks for your feedback.
My requirement is to extract the images and saved in separate word document.
After the extraction the extracted images are removed from the document and also place a bookmark and style in that location(before the fig caption).
please help me to put a style in that place.
Thanks & Regards,
pria
@akshayapria,
Thanks for your inquiry. You just need to move the cursor to the fig caption (Paragraph node) and insert the desired content. Please check the documentation links shared in my old post.
