This pull request introduces a new feature for converting EML (email)
files to PDF format, along with various customization options. It
includes backend support for the conversion process, frontend
integration for user interaction, and updates to localization and
navigation.
### Backend Changes:
* **Added EML to PDF Conversion Logic**: Implemented a new controller
`ConvertEmlToPDF` with an endpoint `/api/v1/convert/eml/pdf` to handle
EML-to-PDF conversion requests. This includes validation, support for
HTML intermediate files, and enhanced options such as attachment
handling and size limits.
(`src/main/java/stirling/software/SPDF/controller/api/converters/ConvertEmlToPDF.java`)
* **New Model for Conversion Requests**: Introduced `EmlToPdfRequest`
class to encapsulate request parameters like attachment inclusion,
maximum attachment size, and HTML download options.
(`common/src/main/java/stirling/software/common/model/api/converters/EmlToPdfRequest.java`)
* **Dependency Update**: Added `jakarta.mail:jakarta.mail-api:2.1.3` to
the project dependencies for handling EML files. (`common/build.gradle`)
### Frontend Changes:
* **New Web Form**: Created a new HTML page `eml-to-pdf.html` for the
EML-to-PDF conversion tool, allowing users to upload EML files and
configure options.
(`src/main/resources/templates/convert/eml-to-pdf.html`)
* **Navigation Update**: Added a navigation entry for the EML-to-PDF
tool in the sidebar.
(`src/main/resources/templates/fragments/navElements.html`)
### Localization and UI Enhancements:
* **Localization Strings**: Added support for the EML-to-PDF tool in the
`messages_en_GB.properties` file, including titles, descriptions, and
help texts. (`src/main/resources/messages_en_GB.properties`)
* **Web Controller Update**: Added a new route `/eml-to-pdf` in
`ConverterWebController` to serve the EML-to-PDF form.
(`src/main/java/stirling/software/SPDF/controller/web/ConverterWebController.java`)
### Highlights:
* Attachment support: and Attachment section is created with fully
working PDFAnnotations, which enable users to click paperclip and
redirects to the attachment. (Requires PDF.js)
* If attachments are present creates a catalog of attachments
* Encoding support inside the body and header for local charachters e.g:
ö,ő,ü etc..
* Optional: Users can download HTMLs, aswell as PDFs
* Advanced features for conversion that: keep links, keep as much
formatting as possible, keep images incl relative sizes, popular fonts
and many more.
### Known limitations
* Generally EML-to-HTML is very reliable however emails with complicated
layout cause problem for Weasyprint, so not all emails can reliably
converted to PDF.
* Users need PDF.js and PDFCatalog support for best attachment/embedding
support (but is not strict requirement)
### Challanges
* Embedding was a large headache, not the Embedding itself per se more
so the additional niceties such as: links, the catalog, consistent
symbols (replaced the paperclip that is generated by pdf viewer with
emoji paperclip that is consistent for everybody) and it was generally
prone all sorts of hard to diagnose issues.
* Encoding issues
* Formatting issues
However I think addressed these so shouldn't cause any additional
headache. :)
### Examples:
Closes#503
