Convert HTML to WMF via Java

Export HTML file to WMF within any within any Java J2SE, J2EE, J2ME applications without using Adobe^® Acrobat Reader

Converting an HTML file to a WMF image in Java can be done in two easy steps. The first step is to use the Aspose.PDF for Java API to export the HTML file to a JPEG image. Aspose.PDF for Java is a part of the Aspose.Total for Java package, which is a suite of APIs for manipulating various file formats. Once the HTML file has been converted to a JPEG image, the second step is to use the Aspose.Imaging for Java API to render the JPEG image to a WMF image. Aspose.Imaging for Java is an image processing API that can be used to manipulate various image formats.

To begin the conversion process, you will need to install the Aspose.Total for Java package. Once the package is installed, you can use the Aspose.PDF for Java API to export the HTML file to a JPEG image. This can be done by using the Document.save method, which takes the HTML file as an input and outputs a JPEG image. After the HTML file has been converted to a JPEG image, you can use the Aspose.Imaging for Java API to render the JPEG image to a WMF image. This can be done by using the Image.save method, which takes the JPEG image as an input and outputs a WMF image.

By following these two simple steps, you can easily convert an HTML file to a WMF image in Java. The Aspose.Total for Java package provides all the necessary APIs for manipulating various file formats, making it easy to convert HTML files to WMF images.

Export HTML to WMF via Java

Open HTML file using Document class
Initialize class object and render HTML to JPEG by using Process method
Load JPEG file by using Image class
Save the document to WMF format using save method

Conversion Requirements

You can easily use Aspose.Total for Java directly from a Maven based project and include libraries in your pom.xml.

Alternatively, you can get a ZIP file from downloads .

Convert HTML to WMF in a Single File via Java

The API also allows you to export HTML file to WMF to a single file. In order to convert all pages, you can first render your HTML document to one TIFF file and after that, you can export the TIFF file to WMF. You can open the input file using Document class and create Resolution, TiffSettings, & TIFF device objects. You can get a single TIFF image using process method of TiffDevice class. Finally, you can load TIFF file using Image class and save it to WMF format using save method.

	// supports PDF, CGM, EPUB, TeX, PCL, PS, XPS, MD, MHTML, XSLFO, HTML file formats
	// load PDF with an instance of Document
	Document pdfDocument = new Document("input.pdf");

	// Create Resolution object
	Resolution resolution = new Resolution(300);

	// Create TiffSettings object
	TiffSettings tiffSettings = new TiffSettings();
	tiffSettings.setCompression(CompressionType.None);
	tiffSettings.setDepth(ColorDepth.Default);
	tiffSettings.setShape(ShapeType.Landscape);

	// Create TIFF device
	TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings);

	// Convert a particular page and save the image to stream
	tiffDevice.process(pdfDocument, 1, 1, "output.tif");

	// load TIFF file
	Image image = Image.Load("output.tif");
	// supports Dicom, Jpeg2000, Apng, Psd, Dxf, Wmf, Emz, Wmz, Tga, Svgz file formats
	// save TIFF to PSD file format
	image.save("output.psd", new PsdOptions());

Convert HTML to WMF With Watermark via Java

Using the API, you can also export HTML file to WMF with watermark in your WMF document. In order to add a watermark to you can first convert HTML to JPEG and add a watermark in it. In order to add watermark, load an image file using the Image class, create an object of the Graphics class and initialize it with Image object, create a new Matrix object and set translation and transformation to the desired angle and add watermark using Graphics.drawString method. After adding the watermark in your image, you can save the JPEG as WMF format.

	// supports PDF, CGM, EPUB, TeX, PCL, PS, XPS, MD, MHTML, XSLFO, HTML file formats
	// load PDF with an instance of Document
	Document document = new Document("input.pdf");

	// create an object of JpegDevice
	JpegDevice renderer = new JpegDevice();

	// convert first of a particular PDF page to JPEG format
	renderer.process(document.getPages().get_Item(1), "output.jpeg");

	// load JPEG
	Image image = Image.load("output.jpeg");

	// create and initialize an instance of Graphics class
	Graphics graphics= new Graphics(image);

	// create an instance of Font
	Font font = new Font("Times New Roman", 16, FontStyle.Bold);

	// create an instance of SolidBrush and set its properties
	SolidBrush brush = new SolidBrush();
	brush.setColor(Color.getBlack());
	brush.setOpacity(100);

	Size sz = graphics.getImage().getSize();
	// create an object of Matrix class for transformation
	Matrix matrix = new Matrix();

	// first a translation then a rotation
	matrix.translate(sz.getWidth() / 2, sz.getHeight() / 2);
	matrix.rotate(-45.0f);

	// set the Transformation through Matrix
	graphics.setTransform(matrix);

	// draw a string using the SolidBrush and Font objects at specific point
	graphics.drawString("Watermark by Aspose.Imaging for Java", font, brush, 0, 0);

	// supports Dicom, Jpeg2000, Apng, Psd, Dxf, Wmf, Emz, Wmz, Tga, Svgz file formats
	// save JPEG to PSD file format
	image.save("output.psd", new PsdOptions());

Convert & Rotate HTML to WMF File via Java

Using the API, you can also rotate the output WMF image as per your needs. The Image.rotateFlip method can be used to rotate the image by 90/180/270-degrees and flip the image horizontally or vertically. The library provides simple methods to perform complex operations while encapsulating all ugly details. You can specify the type of rotation and flip to apply to the image. In order to rotate and flip the image, you can load the converted JPEG image using the Image class and call the Image.rotateFlip method while specifying the appropriate RotateFlipType .

	// supports PDF, CGM, EPUB, TeX, PCL, PS, XPS, MD, MHTML, XSLFO, HTML file formats
	// load PDF with an instance of Document
	Document document = new Document("input.pdf");

	// create an object of JpegDevice
	JpegDevice renderer = new JpegDevice();

	// convert first of a particular PDF page to JPEG format
	renderer.process(document.getPages().get_Item(1), "output.jpeg");

	// load JPEG file
	Image image = Image.Load("output.jpeg");
	// roate image
	image.RotateFlip(RotateFlipType.Rotate270FlipNone);
	// supports Dicom, Jpeg2000, Apng, Psd, Dxf, Wmf, Emz, Wmz, Tga, Svgz file formats
	// save JPEG to PSD file format
	image.save("output.psd", new PsdOptions());
