java.lang.Object

com.aspose.words.PdfImageCompression

public class PdfImageCompression
extends java.lang.Object

Specifies the type of compression applied to images in the PDF file.

Examples:

Shows how to specify a compression type for all images in a document that we are converting to PDF.

 
 Document doc = new Document();
 DocumentBuilder builder = new DocumentBuilder(doc);

 builder.writeln("Jpeg image:");
 builder.insertImage(getImageDir() + "Logo.jpg");
 builder.insertParagraph();
 builder.writeln("Png image:");
 builder.insertImage(getImageDir() + "Transparent background logo.png");

 // Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
 // to modify how that method converts the document to .PDF.
 PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();

 // Set the "ImageCompression" property to "PdfImageCompression.Auto" to use the
 // "ImageCompression" property to control the quality of the Jpeg images that end up in the output PDF.
 // Set the "ImageCompression" property to "PdfImageCompression.Jpeg" to use the
 // "ImageCompression" property to control the quality of all images that end up in the output PDF.
 pdfSaveOptions.setImageCompression(pdfImageCompression);

 // Set the "JpegQuality" property to "10" to strengthen compression at the cost of image quality.
 pdfSaveOptions.setJpegQuality(10);

 doc.save(getArtifactsDir() + "PdfSaveOptions.ImageCompression.pdf", pdfSaveOptions);
