Converting HTML to PDF Using iText
HTMLWorker Inefficiency and CSS Compatibility
HTMLWorker, despite its deprecation, has limitations. It does not consider CSS styling and requires manual image provision to prevent errors. It also requires deprecated objects and methods for operation.
XML Worker and Image Handling
While XML Worker initially showed promise, it faced image display issues. By incorporating an ImageProvider and configuring CSS, the image can be displayed, but its positioning (e.g., floating right) remained unaddressed.
Resolving Positional CSS Issues
In iText 7.1.0 with pdfHTML 2.0.0, CSS positioning is resolved. The code simplifies to this:
HtmlConverter.convertToPdf(new File(src), new File(dest));
Benefits of iText 7 and pdfHTML 2
iText 7 offers a streamlined and powerful HTML to PDF conversion. It automatically respects CSS, including float positioning, and supports various HTML elements.
Mitigating Concerns About Licensing and Legacy Systems
iText 7 is available under the AGPL, allowing free use for open source projects. Closed source uses require a commercial license. Legacy systems using older iText versions should migrate to iText 7 for maintenance and security reasons.
The above is the detailed content of How Can iText 7 and pdfHTML 2 Efficiently Convert HTML to PDF, Handling CSS and Images?. For more information, please follow other related articles on the PHP Chinese website!
What are the advantages of using bytecode over native code for platform independence?Apr 30, 2025 am 12:24 AMBytecodeachievesplatformindependencebybeingexecutedbyavirtualmachine(VM),allowingcodetorunonanyplatformwiththeappropriateVM.Forexample,JavabytecodecanrunonanydevicewithaJVM,enabling"writeonce,runanywhere"functionality.Whilebytecodeoffersenh
Is Java truly 100% platform-independent? Why or why not?Apr 30, 2025 am 12:18 AMJava cannot achieve 100% platform independence, but its platform independence is implemented through JVM and bytecode to ensure that the code runs on different platforms. Specific implementations include: 1. Compilation into bytecode; 2. Interpretation and execution of JVM; 3. Consistency of the standard library. However, JVM implementation differences, operating system and hardware differences, and compatibility of third-party libraries may affect its platform independence.
How does Java's platform independence support code maintainability?Apr 30, 2025 am 12:15 AMJava realizes platform independence through "write once, run everywhere" and improves code maintainability: 1. High code reuse and reduces duplicate development; 2. Low maintenance cost, only one modification is required; 3. High team collaboration efficiency is high, convenient for knowledge sharing.
What are the challenges in creating a JVM for a new platform?Apr 30, 2025 am 12:15 AMThe main challenges facing creating a JVM on a new platform include hardware compatibility, operating system compatibility, and performance optimization. 1. Hardware compatibility: It is necessary to ensure that the JVM can correctly use the processor instruction set of the new platform, such as RISC-V. 2. Operating system compatibility: The JVM needs to correctly call the system API of the new platform, such as Linux. 3. Performance optimization: Performance testing and tuning are required, and the garbage collection strategy is adjusted to adapt to the memory characteristics of the new platform.

Explain how the JVM acts as an intermediary between the Java code and the underlying operating system.Apr 29, 2025 am 12:23 AMJVM works by converting Java code into machine code and managing resources. 1) Class loading: Load the .class file into memory. 2) Runtime data area: manage memory area. 3) Execution engine: interpret or compile execution bytecode. 4) Local method interface: interact with the operating system through JNI.
Explain the role of the Java Virtual Machine (JVM) in Java's platform independence.Apr 29, 2025 am 12:21 AMJVM enables Java to run across platforms. 1) JVM loads, validates and executes bytecode. 2) JVM's work includes class loading, bytecode verification, interpretation execution and memory management. 3) JVM supports advanced features such as dynamic class loading and reflection.
What steps would you take to ensure a Java application runs correctly on different operating systems?Apr 29, 2025 am 12:11 AMJava applications can run on different operating systems through the following steps: 1) Use File or Paths class to process file paths; 2) Set and obtain environment variables through System.getenv(); 3) Use Maven or Gradle to manage dependencies and test. Java's cross-platform capabilities rely on the JVM's abstraction layer, but still require manual handling of certain operating system-specific features.
