Issue with rendering PPTX Notes in HTML

Aspose.Slides Product Family
1

Note: This thread is different from our another thread in notes - Free Support Forum - aspose.com

Here we create a new PPTX and created a notes initially, and never edited the notes again (which is problematic as we described in another mail). This thread specifically for rendering issues I found.

Please find attached ZIP file containing PPTX and converted HTMLs.

Please use code -
for (int i = 0; i < pres.getSlides().size(); i++) {


ITextFrame tf = pres.getSlides().get_Item(i).getNotesSlide().getNotesTextFrame();
// System.out.println(tf.getParagraphs().exportToHtml(0, tf.getParagraphs().getCount(), null));
//
try {
//Creating output html file
OutputStream os = new FileOutputStream(“Hell_” + i + “.html”);
Writer writer = new OutputStreamWriter(os, “UTF16”);

// Extracting first paragraph as HTML
//Writing Paragraphs data to HTML by providing paragraph starting index, total paragraphs to be copied
writer.write(tf.getParagraphs().exportToHtml(0, tf.getParagraphs().getCount(), null));
writer.close();
} catch (Exception fo) {
throw new RuntimeException(fo);

}
}


You may see problem in HTML -

Hellooo
first
𝐴=𝜋𝑟^2
note. 55.
Hello

Hello
World

Hello
first
𝐴=𝜋𝑟^2
note. 55

We want this -

Any help would be appreciated.

Thanks.

Hi Manisha,


I like to share with you that we have investigated the issue as shared by you. I request you to please try using following sample code on your end to serve the purpose, and then share the feedback with us.

Presentation pres = new Presentation(“D:\More+Hell\PowerPoint Notes.pptx”);
for (int i = 0; i < pres.getSlides().size(); i++) {
ITextFrame tf = pres.getSlides().get_Item(i).getNotesSlide().getNotesTextFrame();

try {
//Creating output html file
OutputStream os = new FileOutputStream(“D:\More+Hell\Hell_” + i + “.html”);
Writer writer = new OutputStreamWriter(os, “UTF16”);
// Initializing conversion options
TextToHtmlConversionOptions options = new TextToHtmlConversionOptions();
options.setTextInheritanceLimit(TextInheritanceLimit.TextBox); //Inherit only from TextFrame’s style.

writer.write(tf.getParagraphs().exportToHtml(0, tf.getParagraphs().getCount(), options));
writer.close();
}
catch (Exception fo) {
throw new RuntimeException(fo);
}
}

Please let us know if the issue persists. We will be happy to assist you further.

Hi,

Thanks for providing the solution for the above issue. This solution works fine for the sample powerpoint presentation provided in above posts.

We are still facing some issues in rendering notes in html for some powerpoint presentation.
The powerpoint and notes html file (zip file) is attached with this post. You can see in html file that spacing between lines is not correct and hence we are seeing some lines getting overlapped.


The code used is given below:


public void generateHtmlNotesFromAllSlides(byte[] inputPpt) {

InputStream inputStream = new ByteArrayInputStream(inputPpt);
Presentation presentation= new Presentation(inputStream);

for (int i = 0; i < presentation.getSlides().size(); i++) {
String notes = null;
INotesSlide noteSlide = presentation.getSlides().get_Item(i).getNotesSlide();
if (noteSlide != null) {
ITextFrame tf = noteSlide.getNotesTextFrame();
TextToHtmlConversionOptions options = new TextToHtmlConversionOptions();
options.setTextInheritanceLimit(TextInheritanceLimit.TextBox);
options.setEncodingName(“UTF16”);
notes = tf.getParagraphs().exportToHtml(0, tf.getParagraphs().getCount(), options);
OutputStream os = new FileOutputStream(“note_”+(i+1)+".html");
Writer writer = new OutputStreamWriter(os, “UTF16”);
writer.write(notes);
writer.close();
}

}
}

Thanks
