≪ Previous: Out of memory exception

Hi,

Issue here is:
When I convert document from HTML to PDF (using download option), page numbers are not showing.

I don't create page numbers in footer, just converting from HTML to PDF.

Html for footer is:

1

</div>

</div>

Code for converting HTML to PDF:

input = new ByteArrayInputStream(documentDomain.getHtmlContent().getBytes("UTF-8"));
com.aspose.pdf.Document doc = new com.aspose.pdf.Document(input);            
out = new ByteArrayOutputStream();
doc.save(out, com.aspose.words.SaveFormat.PDF);

If I create page numbers everything works fine, but I don't want to create page numbers in footer if it already exists.

Do you know what is a problem here?

This is working for Word but for PDF not.
I attached both Word and PDF.

Regards

Missing Assembly error (Aspose.Font and Aspose.HTML) and table formatting error

≪ Previous: ASPOSE.PDF HtmlFragment Size Limit Issue

Hello,

as in Thread https://www.aspose.com/community/forums/thread/835575.aspx mentioned does Aspose.Pdf 17.1 and newer throw the Assemly Aspose.Font missing error.

We updated all the dll's to the newest version (see below), but due to the problem mentioned above, we have to use an older version of Aspose.Pdf.

Unfortunytely, from version 16.10 on, a FileNotFoundException is thrown, because the Aspose.HTML assemly is missing, when we load an HTML document into an Aspose.Pdf document, including an HTMLLoadOption to define a CustomLoaderOfExternalResources:

Aspose.Pdf.HtmlLoadOptions htmlOptions = new Aspose.Pdf.HtmlLoadOptions(folderUrl);

htmlOptions.CustomLoaderOfExternalResources = uri => { //handling of referenced files };

Aspose.Pdf.Document htmlDocument = new Aspose.Pdf.Document(memoryStream, htmlOptions) { IgnoreCorruptedObjects = true };

I tested ALL versions starting from 11.2.0 to 16.12.0 regarding both missing assembly errors - the result:
we have to use the Aspose.Pdf 12.0.0 version, but this version does not render tables correctly (see attachment - the blackening in the screenshot is due to data protection).

So, right now, our only possibility to convert an HTML file into PDF is to use Aspose.PDF version 12.0.0, including the table rendering issue...that is really, really frustrating!

.Net 3.5, SharePoint 2010, Windows Server 2008 R2

Aspose.Pdf 12.0.0.0

Aspose.Cells 17.5.0.0

Aspose.Email 17.4.0.0

Aspose.Imaging 17.4.0.0

Aspose.Slides 17.4.0.0

Aspose.Words 17.5.0.0

HtmlLoadOptions for HtmlFragment

≫ Next: Not all PDF Form Fields Being Returned

≪ Previous: Is it possible to have TextAnnotation in XML

I have snippets of HTML that I want to add to my pdf. The html Snippets have images embeded as base64 string in the html itself.

When I add the html snippet as HTMLfragement to page it works fine, but when the images are big it cuts of the image.. Following is the code I am doing

row = table.getRows().add();
c = row.getCells().add();
HtmlFragment html = new HtmlFragment(i.getComments());

c.getParagraphs().add(html);But when I do the same html snippet with loadoptions and save as
pdf it looks fine.Document htmlDoc = new Document(new ByteArrayInputStream(i.getComments().getBytes(StandardCharsets.UTF_8)),
        htmlLoadOptions);
htmlDoc.save("D:/work/temp_xxx.pdf");Is there a way for me when creating a HTMLFragment, to set the size
like loadOptions ? If not is their a workaround ?

Not all PDF Form Fields Being Returned

June 1, 2017, 9:46 am

≫ Next: Convert HTML to PDF - change font, margin and size

≪ Previous: HtmlLoadOptions for HtmlFragment

I am trying to use Aspose.Pdf to enumerate the form fields in a PDF.

I am using Aspose.Pdf version 2016.08.02 (11.9.0.0). I start by opening the PDF:

Dim document As New Aspose.Pdf.Document(Server.MapPath("~/App_Data/88.pdf"))

I then enumerate the fields in document.Form. For each field, I call a method that displays the information:

For Each fld As Aspose.Pdf.Forms.Field In document.Form

DisplayField(fld)

In the DisplayField method I see if it's a group and, if so, recurse into the children of the group. Otherwise I just display the form field details (this is an ASP.NET application).

Private Sub DisplayField(fld As Aspose.Pdf.Forms.Field)

If fld.IsGroup Then

For Each childFld As Aspose.Pdf.Forms.Field In fld

DisplayField(childFld)

Else

lblOutput.Text &= String.Format("Name={0}, PartialName={1}, FullName={2}, Required={3}, ReadOnly={4}, Value={5}",

fld.Name,

fld.PartialName,

fld.FullName,

fld.Required,

fld.ReadOnly,

fld.Value)

End If

End Sub

The issue, though, is that it only enumerates through a small number of the form fields in the PDF. There are many other (on the same page and other pages) that aren't getting displayed. For instance, the attached PDF has 32 form fields. But when I use the above code, Aspose.Pdf returns only 4 form fields.

Here's the output displayed in the web page. You can see I only get 4 form fields:

Name=, PartialName=box1 pg1, FullName=box1 pg1, Required=False, ReadOnly=False, Value=Yes
Name=, PartialName=box2 pg1, FullName=box2 pg1, Required=False, ReadOnly=False, Value=
Name=, PartialName=box3 pg1, FullName=box3 pg1, Required=False, ReadOnly=False, Value=
Name=, PartialName=fname1 pg1, FullName=fname1 pg1, Required=False, ReadOnly=False, Value=The Village Family Services

How do I get ALL form fields?

What's interesting, it that if I debug and view in the Immediate Window the following:

document.Form.Count

I get back 32 (as to be expected).

But if I do:

document.Form.Fields.Count

I get back 4, which would explain why it only shows four form fields. When I step through the code I see that the loop is only iterated through 4 times. So what gives? How do I loop through all 32 form fields?

Hello!

I'm trying to use a TrueType font on a field in a PDF. The font is embedded in the document and I can use the font for text, but the field seems to be ignoring the font.

Apose version is 17.6.0

// Here I create my font object
Font steveFont = Aspose.Pdf.Text.FontRepository.OpenFont(@"C:\Work\TF_DEV\WOW.EAPP.Common\1_DEVL\WebServices\EAppServices\STEVE.TTF");
steveFont.IsEmbedded = true;

// Here I create my appearance object
var steveAppearance = new DefaultAppearance(steveFont, fontSize, System.Drawing.Color.DarkBlue);
steveAppearance.FontName = "SteveHandwriting";

// Later, I call this method to build the TextBoxField and pass steveAppearance to this method.
private TextBoxField CreatePiSigTextBox(Document pdfDocument, DefaultAppearance appearance)
{
    if (log.IsDebugEnabled) log.DebugFormat(CultureInfo.InstalledUICulture, $"CreatePiSigTextBox called");
    TextBoxField piSigTextBox = new TextBoxField(pdfDocument.Pages[page], GenerateSigRectangle(signatureCoordinates.piSigXpos, signatureCoordinates.piSigYpos));
    piSigTextBox.HorizontalAlignment = HorizontalAlignment.Left;
    piSigTextBox.PartialName = "SIG_X_APPCNT";
    piSigTextBox.DefaultAppearance = appearance;
    return piSigTextBox;
}

We tried some other fonts, too, but we can't see to get the field to change. Any suggestions?

I need to replace a hyperlink (text and url) in a pdf document, I tried the following code

break;

   document.Save(filename1);

It changes the URL of the hyperlink but not the text. How to change the display text, I tried two methods

simple text replace which replaced but I can see a long underline after the hyperlink text

then I tried the following...

// a is retrieved from the above code ***

                        TextFragmentAbsorber ta = new TextFragmentAbsorber();                        Aspose.Pdf.Rectangle rect = a.Rect;                        rect.LLX -= 10;                        rect.LLY -= 10;                        rect.URX += 10;                        rect.URY += 10;                        ta.TextSearchOptions = new TextSearchOptions(rect);                        ta.Visit(document.page);  // page is coming from the above logic                        // Change color and text.                        foreach (TextFragment tf in ta.TextFragments)                        {                            tf.TextState.ForegroundColor = Aspose.Pdf.Color.Red;                            tf.Text = "Click Here";                        }                        break;

but this replaces  the text but many times as attached(after.img), "Click Here" is appeared many times in the same sentence and the hyperlink format (underline and blue colored text are not disappearing from the previous long URL)
It would be helpful if you give me some suggestion to resolve this issue ,its bit urgent.
otherwise, what is the best way to delete the existing hyperlinks (text and url) and add a new one at the same location? can I have the sample code ?

Please check the attached images.
