Convert HTML to DICOM via Java
Export HTML file to DICOM within any within any Java J2SE, J2EE, J2ME applications without using Adobe® Acrobat Reader
Converting an HTML file to a DICOM image in Java is a simple two-step process. 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 part of the Aspose.Total for Java package, which includes a range of APIs for working with documents, images, and other 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 DICOM image. Aspose.Imaging for Java is an image processing API that provides a range of features for manipulating images, including the ability to convert between different image formats.
By using the two APIs together, you can easily convert an HTML file to a DICOM image in Java. The process is straightforward and requires minimal coding, making it an ideal solution for developers who need to convert HTML files to DICOM images.

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 DICOM in a Single File via Java
The API also allows you to export HTML file to DICOM 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 DICOM. 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 DICOM 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 DICOM With Watermark via Java
Using the API, you can also export HTML file to DICOM with watermark in your DICOM 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 DICOM 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 DICOM File via Java
Using the API, you can also rotate the output DICOM 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()); |

What is HTML File Format?
HTML, or HyperText Markup Language, is a crucial language used for creating web pages. It provides structure and formatting to the content displayed on websites. HTML utilizes tags enclosed in angle brackets (< and >) to define elements and their properties within a web page.
Developers employ HTML to define headings, paragraphs, lists, images, links, tables, forms, and various other elements necessary for creating a rich and interactive web experience. Attributes within tags offer additional information or functionality and are typically defined as name-value pairs.
HTML serves as the backbone of web development, allowing content to be separated from presentation. It is often combined with CSS (Cascading Style Sheets) and JavaScript to enhance the design and interactivity of web pages.
By using HTML, developers can create structured documents that are easily understood by web browsers and search engines. The language follows a hierarchical structure, with nested elements representing the relationship between different parts of the content.
HTML enables the development of accessible, responsive, and mobile-friendly websites, accommodating a wide range of devices and users. Its semantic markup assists search engines in better understanding the content, thus improving the website’s visibility in search results.
HTML is the foundation of web development, providing the necessary structure and formatting for creating web pages. Its simplicity, flexibility, and broad support make it an essential language for building effective websites that deliver content seamlessly across various platforms and devices.
What is DICOM File Format?
Digital Imaging and Communications in Medicine (DICOM) is a standard for storing and transmitting medical images. It includes a file format definition and a network protocol. DICOM files can be exchanged between two entities, such as a medical imaging device and a picture archiving and communication system (PACS), or between two PACS. DICOM enables the integration of medical imaging devices and information systems.DICOM files are composed of a file header and a series of data sets. The file header contains information about the file, such as the DICOM version, the transfer syntax used, the patients name, and the study date. The data sets contain the image data and associated information, such as the patient ID, the image modality, and the image orientation.DICOM files can be exchanged over a network using the DICOM protocol. The DICOM protocol is a set of rules that define how DICOM files are to be transmitted. The protocol is based on the TCP/IP protocol.
