Fixes and Improvements

・Support direct use of SVG content in image URLs without requiring Base64 encoding.

・Support the aspect-ratio attribute on <img> elements to keep image proportions consistent with browser rendering.

・Automatically select the font weight specified by font-weight when a single font file contains multiple weights, instead of always using the lightest weight.

・Automatically download and use Google Fonts referenced by the page.

・Strengthen TLS certificate validation for native online resource requests and restrict certificate configuration to supported trust store paths.

・Update the embedded CA certificate bundle used for native network resource loading to fix certificate chain validation issues.

・Improve the handling of certificate validation failures and remote resource errors when loading online fonts, images, and other external resources.

・Improve security checks during remote resource loading to prevent access to external resources that do not comply with the security policy.

New Features

・Added CEmailConverter APIs for converting EML and Outlook MSG messages to HTML or PDF from file paths, File objects, byte arrays, and input streams.

・Added email format detection, configurable byte budgets, cooperative cancellation, conversion status codes, and detailed diagnostics.

・Added page margin configuration APIs for setting and reading the top, right, bottom, and left margins in CSS pixels.

・Added HTML header and footer options, including templates, resource base URI, title, URL, date, page counters, and controls for skipping cover pages and numbering pages.

Fixes and Improvements

・Improved native library extraction and loading by using a dedicated Java temporary directory.

・Updated Linux native dependencies for PNG and JPEG image decoding.

・Added resource lifetime checks, callback reentry protection, and Java stream/cancellation exception reporting for email conversion.

Samples and Documentation

・Added EmailConvertTest examples for EML/MSG parsing, export of HTML packages, PDF generation with headers and footers, and stream conversion.

・Added PrintOptionsTest and FamilyHeaderFooterTest examples for page margins, header/footer templates, cover pages, and page numbering.

・Expanded public API comments and regenerated the Java API Reference, including the email conversion interfaces.

Compatibility and Usage

・This release package targets Linux x86_64 and Java 8 or higher. Use the matching JAR and native library.

・PDF generation requires a valid initialized license. Email parsing and HTML export require the native library to be loaded but do not require a license.

・Email PDF output contains the message body and an optional attachment list. Attachment files are exported separately with the HTML package; they are not embedded in the PDF or rendered as additional pages.

For API details and examples, open API Reference/index.html or consult develop_guide_java_en.pdf and develop_guide_java_zh.pdf in the SDK package.
