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.


Document doc = new Document ("inputFileName");
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF);
options.setThresholdForFloydSteinbergDithering((byte)127);"outputFileNameC.tiff", options);
