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.
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.
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.
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 .
