Public API Changes

ISVGOptions.UseFrameSize and ISVGOptions.UseFrameRotation have been added

New properties UseFrameSize and UseFrameRotation have been added to the ISVGOptions interface and SVGOptions class.

The UseFrameSize property allows determines whether the text frame will be included in a rendering area.

Property declaration:

/// <summary>
/// Determines whether the text frame will be included in a rendering area or not.
/// Read/write <see cref="bool"/>.
/// Default value is false.
/// </summary>
bool UseFrameSize { get; set; }

The UseFrameRotation property allows determines whether to perform the specified rotation of the shape when rendering.

Property declaration:

/// <summary>
/// Determines whether to perform the specified rotation of the shape when rendering or not.
/// Read/write <see cref="bool"/>.
/// Default value is true.
/// </summary>
bool UseFrameRotation { get; set; }

The code snippet below demonstrates using these properties:

using (Presentation pres = new Presentation("pres.pptx"))
    SVGOptions svgOptions = new SVGOptions();

    // Does not perform the specified rotation of the shape while rendering to SVG.
    svgOptions.UseFrameRotation = false;

    // Include the text frame in a rendering area while rendering to SVG.
    svgOptions.UseFrameSize = true;

    // Save shape to SVG
    using (FileStream stream = new FileStream("pres-out.svg", FileMode.Create))
        pres.Slides[0].Shapes[1].WriteAsSvg(stream, svgOptions);

Embedded fonts compress feature added

Embedded fonts can be compressed to decrease the size of the presentation that contains such fonts. To provide this functionality, the CompressEmbeddedFonts method was added to LowCode API.

Below is the snippet demonstrating compression:

using (Presentation pres = new Presentation("pres.pptx"))
    pres.Save("pres-out.pptx", SaveFormat.Pptx);

LeaderLinesColor porperty has been added

The LeaderLinesColor property has been addded, now the color of all leader lines in the collection can be managed via this property:

using (Presentation pres = new Presentation("pres.pptx"))
    IChart chart = (IChart) pres.Slides[0].Shapes[0];
    IChartSeriesCollection series = chart.ChartData.Series;
    IDataLabelCollection labels = series[0].Labels;
    labels.LeaderLinesColor = Color.FromArgb(255, 255, 0, 0);
