com.aspose.words.PdfImageColorSpaceExportMode

public class PdfImageColorSpaceExportMode
extends java.lang.Object

Specifies how the color space will be selected for the images in PDF document.

Examples:

Shows how to set a different color space for images in a document as we export it 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 "ImageColorSpaceExportMode" property to "PdfImageColorSpaceExportMode.Auto" to get Aspose.Words to
 // automatically select the color space for images in the document that it converts to PDF.
 // In most cases, the color space will be RGB.
 // Set the "ImageColorSpaceExportMode" property to "PdfImageColorSpaceExportMode.SimpleCmyk"
 // to use the CMYK color space for all images in the saved PDF.
 // Aspose.Words will also apply Flate compression to all images and ignore the "ImageCompression" property's value.
 pdfSaveOptions.setImageColorSpaceExportMode(pdfImageColorSpaceExportMode);

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

Field Detail

AUTO

public static int AUTO

Aspose.Words automatically selects the most appropriate color space for each image.

Remarks:

Most of the images are saved in RGB color space. Also Indexed and Grayscale color spaces may be used. CMYK color space is never used.

For some images the color space may be different on different platforms.

SIMPLE_CMYK

public static int SIMPLE_CMYK

Aspose.Words coverts RGB images to CMYK color space using simple formula.

Remarks:

Images in RGB color space are converted to CMYK using formula: Black = minimum(1-Red,1-Green,1-Blue). Cyan = (1-Red-Black)/(1-Black). Magenta = (1-Green-Black)/(1-Black). Yellow = (1-Blue-Black)/(1-Black). RGB values are normalized - they are between 0 and 1.0.
