Property Value

Type: Int32


Has effect only when saving to JPEG.

Use this property to get or set the quality of generated images when saving in JPEG format. The value may vary from 0 to 100 where 0 means worst quality but maximum compression and 100 means best quality but minimum compression.

The default value is 95.


Shows how to configure compression while saving a document as a JPEG.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertImage(ImageDir + "Logo.jpg");

// Create an "ImageSaveOptions" object which we can pass to the document's "Save" method
// to modify the way in which that method renders the document into an image.
ImageSaveOptions imageOptions = new ImageSaveOptions(SaveFormat.Jpeg);

// Set the "JpegQuality" property to "10" to use stronger compression when rendering the document.
// This will reduce the file size of the document, but the image will display more prominent compression artifacts.
imageOptions.JpegQuality = 10;

doc.Save(ArtifactsDir + "ImageSaveOptions.JpegQuality.HighCompression.jpg", imageOptions);

Assert.That(20000, Is.AtLeast(new FileInfo(ArtifactsDir + "ImageSaveOptions.JpegQuality.HighCompression.jpg").Length));

// Set the "JpegQuality" property to "100" to use weaker compression when rending the document.
// This will improve the quality of the image at the cost of an increased file size.
imageOptions.JpegQuality = 100;

doc.Save(ArtifactsDir + "ImageSaveOptions.JpegQuality.HighQuality.jpg", imageOptions);

Assert.That(60000, Is.LessThan(new FileInfo(ArtifactsDir + "ImageSaveOptions.JpegQuality.HighQuality.jpg").Length));
