• Fixed a bug when gradient fill is not rotated with DrawingML shapes by default.
• Fixed a bug that caused an incorrect rendering of DrawingML shapes inside groups when 3D rotation was applied.

• Fixed a bug with vertical alignment of Ruby objects while rendering.
• Fixed a bug that caused the creation of extra link tags in output PDF when rendering documents with footnotes.
• Supported dynamic table cell merging for LINQ Reporting Engine.
• Supported textual comments within LINQ Reporting Engine template syntax tags.
• Improved computation of wrap bounds of floating objects which affects position of text nearby.
• Improved positioning of line when it cannot fit next to floating object and has to be pushed below.

Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 19.1. 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.

Exposed the Threshold Control for TIFF Binarization

WORDSNET-17819 has now been resolved:

New public property was added to ImageSaveOptions class:

/// <summary>
/// Gets or sets the threshold that determines the value
/// of the binarization error in the Floyd-Steinberg method.
/// when <see cref="ImageBinarizationMethod"/> is ImageBinarizationMethod.FloydSteinbergDithering.
/// </summary>
/// <remarks>
/// <para>The default value is 128.</para>
/// </remarks>
public byte ThresholdForFloydSteinbergDithering
{
    get { return mThresholdForFloydSteinbergDithering; }
    set { mThresholdForFloydSteinbergDithering = value; }
}

The higher the value, the darker the image.
