Public API and Backward Incompatble Changes

This section lists public API changes that were introduced in Aspose.Words 17.9. It includes not only new and obsoleted public methods, but also a description of any changes in the behavior behind the scenes in Aspose.Words which may affect existing code. Any behavior introduced that could be seen as a regression and modifies existing behavior is especially important and is documented here.

Added LoadOptions.UpdateDirtyFields, Field.IsDirty and FieldChar.IsDirty Properties

WORDSNET-15686 has been resolved. While working on WORDSNET-15686, we have added three public properties related to the dirty (stale) state of the fields and controlling whether such fields should be updated: 

LoadOptions:

/// <summary>
/// Specifies whether to update the fields with the <c>dirty</c> attribute.
/// </summary>
public boolean getUpdateDirtyFields()
public void setUpdateDirtyFields(boolean value)

Field:

/// <summary>
/// Gets or sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document.
/// </summary>
public boolean isDirty()
public void    isDirty(boolean value)

FieldChar:

/// <summary>
/// Gets or sets whether the current result of the field is no longer correct (stale) due to other modifications
/// made to the document.
/// </summary>
public boolean isDirty()
public void    isDirty(boolean value)

When LoadOptions.UpdateDirtyFields == true, all fields having Field.IsDirty == true or FieldChar.IsDirty == true are updated on document load.

Added OdtSaveOptions.MeasureUnit Property

WORDSNET-15425 has been resolved. Public property added to OdtSaveOptions class:

/// <summary>
/// Allows to specify units of measure to apply to document content.
/// The default value is <see cref="OdtSaveMeasureUnit.Centimeters"/>
/// </summary>
/// <remarks>
/// Open Office uses centimeters when specifying lengths, widths and other measurable formatting and&nbsp;
/// content properties in documents whereas MS Office uses inches.
///</remarks>
public int getMeasureUnit()
public void setMeasureUnit(int value)

Use case:

Document doc = new Document(dataDir + "Document.doc");
OdtSaveOptions saveOptions = new OdtSaveOptions();
saveOptions.setMeasureUnit(OdtSaveMeasureUnit.INCHES);
doc.save(dataDir + "MeasureUnit_out.odt", saveOptions);

Added Public Method StructuredDocumentTag.Clear

Ability to clear contents of a content control with displaying a placeholder is implemented.

/// <summary>
/// Clears contents of this structured document tag and displays a placeholder if it is defined.
/// </summary>
public void clear()

It is not possible to clear contents of a content control if it has revisions. Also, the method does nothing for row-level content controls that have more than one cell (limitation of MS Word). If a content control has no placeholder, five spaces are inserted like in MS Word (except repeating sections, repeating section items, groups, checkboxes, citations). If a content control is mapped to custom XML, the referenced XML node is cleared.

Example of use:

Document doc = new Document(myDir + "document1.docx");
StructuredDocumentTag sdt = (StructuredDocumentTag) doc.getChild(NodeType.STRUCTURED_DOCUMENT_TAG, 0, true);
sdt.clear();
doc.save(myDir + "document1.docx");

Added Public Property List.IsRestartAtEachSection.

Related issue: WORDSNET-15054

Public property added to the List class to support backward compatibility upon Mail Merge, please see WORDSNET-15054.

/// <summary>
/// Specifies whether list should be restarted at each section.
/// Default value is <b>false</b>.
/// </summary>
/// <remarks>
/// <p>This option is supported only in RTF, DOC and DOCX document formats.</p>
/// <p>This option will be written to DOCX only if <see cref="OoxmlCompliance"/> is higher then <see cref="OoxmlComplianceCore.Ecma376"/>.</p>
/// </remarks>
public boolean isRestartAtEachSection()
public void isRestartAtEachSection(boolean value)

Use case:

Document doc = new Document();
doc.getLists().add(ListTemplate.NUMBER_DEFAULT);
com.aspose.words.List list = doc.getLists().get(0);

// Set true to specify that the list has to be restarted at each section.
list.isRestartAtEachSection(true);
DocumentBuilder builder = new DocumentBuilder(doc);
builder.getListFormat().setList(list);
for (int i = 1; i < 45; i++) {
    builder.writeln(String.format("List Item " + i));

    // Insert section break.
    if (i == 15)
        builder.insertBreak(BreakType.SECTION_BREAK_NEW_PAGE);
}
builder.getListFormat().removeNumbers();

// IsRestartAtEachSection will be written only if compliance is higher then OoxmlComplianceCore.Ecma376
OoxmlSaveOptions options = new OoxmlSaveOptions();
options.setCompliance(OoxmlCompliance.ISO_29500_2008_TRANSITIONAL);
doc.Save("out.docx", options);

Here is the code snippet for backward compatibility upon Mail Merge:

Dictionary<List, bool> lists = new Dictionary<List, bool>();
foreach (List list in document.Lists)
	lists[list] = list.IsRestartAtEachSection;
document.MailMerge.Execute(...);
foreach (KeyValuePair<List, bool> pair in lists)
	pair.Key.IsRestartAtEachSection = pair.Value

Added SaveOptions.UpdateLastSavedTimeProperty Property

Reference: WORDSNET-7912

While working on WORDSNET-7912, we have added the SaveOptions.UpdateLastSavedTimeProperty property that controls whether to update the corresponding built-in document property on document save.

/// <summary>
/// Gets or sets a value determining whether the <see cref="BuiltInDocumentProperties.LastSavedTime" /> property is updated before saving.
/// </summary>
public boolean getUpdateLastSavedTimeProperty()
public void    setUpdateLastSavedTimeProperty(boolean value)

Document doc = new Document(myDir + "Document.doc");
OoxmlSaveOptions options = new OoxmlSaveOptions();
options.setUpdateLastSavedTimeProperty(true);

// Save the document to disk.
doc.save(myDir+"output.doc", options);
