Public API Changes

TiffOptions.BwConversionMode property and BlackWhiteConversionMode enum added

The new TiffOptions.BwConversionMode property allows you to specify the algorithm for converting a color image to a black and white image. This setting is applied only when CompressionType is set to TiffCompressionTypes.CCITT4 or TiffCompressionTypes.CCITT3.

Example:

$tiffOptions = new TiffOptions();
$tiffOptions->setCompressionType(TiffCompressionTypes::CCITT4);
$tiffOptions->setBwConversionMode(BlackWhiteConversionMode::Dithering);

$presentation = new Presentation();
try {
    $presentation->save($tiffFilePath, SaveFormat::Tiff, $tiffOptions);
} finally {
    if ($presentation != null) $presentation->dispose();
}

InkBrush and InkTrace classes have been added

New classes related to Ink management API have been added:

InkTrace represents a trace element that is used to record the data captured by the digitizer. It contains a sequence of points.
InkBrush represents trace brush.

Example:

$pres = new Presentation("pres.pptx");
try {
    $ink = $pres->getSlides()->get_Item(0)->getShapes()->get_Item(0);
    $traces = $ink->getTraces();
    $brush = $traces[0]->getBrush();
} finally {
    if ($pres != null) $pres->dispose();
}

Paragraph.GetLinesCount method has been added

The new GetLinesCount method of the Paragraph class allows you to get the number of lines in a paragraph.

Example:

$pres = new Presentation();
try {
    $sld = $pres->getSlides()->get_Item(0);
    $ashp = $sld->getShapes()->addAutoShape(ShapeType::Rectangle, 150, 75, 150, 50);
    $para = $ashp->getTextFrame()->getParagraphs()->get_Item(0);
    $portion = $para->getPortions()->get_Item(0);
    $portion->setText("Aspose Paragraph GetLinesCount() Example");
    echo "Lines Count = " . $para->getLinesCount();
} finally {
    if ($pres != null) $pres->dispose();
}
