# Description of Changes
- Introduced **Duplicate Page** action in the MultiTool UI:
- New `DuplicatePageCommand` with full undo/redo support
- Button added next to Delete, with tooltip text wired via i18n
(`multiTool.duplicate`)
- `PdfContainer.duplicatePage()` clones page image, rotation, and
adapter state; inserts after source; refreshes numbering
- Hooked duplication into the actions pipeline:
- `PdfActionsManager` now receives `duplicatePage` via `setActions(...)`
- Added `duplicatePageButtonCallback` and control markup creation
- Refactored command architecture for robust undo/redo:
- Added `CommandWithAnchors` for capturing positions and deterministic
reinsertion (used by add/duplicate/page-break)
- Modernized `AddFilesCommand`, `PageBreakCommand` to use anchors, avoid
DOM state on nodes, and handle arrays consistently
- Improved `RemoveSelectedCommand`, `DeletePageCommand`,
`MovePageCommand`, `Rotate*` and `Split*` commands:
- Safer null checks for filename/export controls
- Clearer semantics and documentation
- Consistent redo mirroring execute
- Minor UI/UX fix:
- Corrected tooltip wiring for the **Add File** button
(`insertFileButton.setAttribute('title', ...)`)
- Internationalization:
- Added `multiTool.duplicate=Duplicate` to `messages_en_GB.properties`
- Exposed `translations.duplicate` in `multi-tool.html`
**Why:** Adds a commonly requested workflow improvement (duplicate a
single page quickly) and makes the command stack more resilient
(especially redo after complex DOM mutations), improving reliability and
maintainability.

# Description of Changes
**What was changed**
- Added enterprise configuration for database-related email
notifications:
-
`premium.enterpriseFeatures.databaseNotifications.backups.successful|failed`
-
`premium.enterpriseFeatures.databaseNotifications.imports.successful|failed`
- Extended `ApplicationProperties` and `settings.yml.template`
accordingly.
- Introduced `DatabaseNotificationServiceInterface` and
`DatabaseNotificationService` to centralize and gate notification
sending (EE-only, respects `mail.enabled`).
- Wired notifications into `DatabaseService`:
- Sends emails on successful/failed **backups** and **imports**.
- Added backup verification step:
- Compute SHA‑256 checksum for backup files.
- Validate backup by loading it into an in‑memory H2 instance
(`RUNSCRIPT`) before using it.
- Abort import if verification fails.
- Enhanced `EmailService`:
- Added `sendSimpleMail(String to, String subject, String body)` (async)
for lightweight notifications.
- Added debug logging for successful sends.
- Minor refactors and improved logging around backup/export/import
flows.
**Why the change was made**
- Provide admins with timely, configurable notifications about critical
database operations (backups/imports).
- Increase reliability by verifying backup integrity before execution,
reducing risk from corrupted or incomplete scripts.
- Keep configuration explicit and self-documenting via new keys in
`settings.yml.template`.

# Description of Changes
- **What was changed**
- Added explicit `@ApiResponses` for filter endpoints with `200` (PDF
passed) and `204` (did not pass) including `@Content` and media types.
- Replaced ambiguous `null` returns with
`ResponseEntity.noContent().build()` when a filter condition is not met.
- Ensured `PDDocument` is properly closed using try-with-resources in
relevant endpoints.
- Consolidated comparison logic into a reusable, type-safe `compare<T
extends Comparable<T>>()` helper for page count, page size, file size,
and rotation checks.
- Minor cleanup and consistency improvements across filter endpoints.
- **Why the change was made**
- To return correct HTTP semantics (avoid ambiguous `null` responses)
and improve API reliability for clients consuming these endpoints.
- To document expected responses clearly in the OpenAPI spec for better
consumer tooling and DX.
- To prevent potential resource leaks by consistently closing
`PDDocument`.

# Description of Changes
### UI and Summary Enhancements
* Added a "Technical Details" section to the PDF summary UI, displaying
information such as images, fonts, color spaces, form fields, embedded
files, JavaScript, layers, bookmarks, and multimedia. This includes new
HTML markup and corresponding translation string.
* Populated the new technical details fields in the summary using data
from the backend response, including logic to count and display images,
fonts, color spaces, form fields, embedded files, JavaScript scripts,
layers, bookmarks, and multimedia items.
### Refactor:
- Refactored getPdfInfo function (which was 400 lines) to multiple
manageable size functions
- Extract magic numbers to named constants:
- `72` (PPI) should be a named constant like `POINTS_PER_INCH`
- `1.0f` (tolerance) should be a named constant like `DEFAULT_TOLERANCE`
- `5` (max logged errors) should be a named constant like
`MAX_LOGGED_ERRORS`
- Make the keyBuilder optimization for page prefixes effective
- Used `String.format()` for better readability in complex string
constructions
- Replace abbreviated variable names with descriptive alternatives:
- `ap` (AccessPermission) → `accessPermission`
- `is` (InputStream) → `inputStream` or `pdfInputStream`
- Improved attachment processing, and other features see below:

# Description of Changes
Rendering on high DPI can needlessly increase the file size and
processing time, even when users would prefer smaller size, (with lesser
quality)
This PR adds support for configurable DPI, so that users can choose
their preferred balance between processing time/file size and quality.
**Backend logic and data model updates:**
* The `FlattenController` now processes an optional `renderDpi`
parameter from the request, using it to set the rendering DPI for each
page. It enforces minimum and maximum values based on system
configuration and ensures a sensible default if not provided.
* The `FlattenRequest` model has a new `renderDpi` field to carry the
requested DPI through the API and backend logic.
**User interface and documentation improvements:**
* The flatten form in `flatten.html` includes a new input field for DPI,
with validation and help text to guide users about its impact and usage.
* English resource messages have been updated to describe the new DPI
field and provide help text explaining its effects.
**UI:**
<img width="595" height="604" alt="image"
src="https://github.com/user-attachments/assets/f78a0401-0348-490b-920a-91475cab224b"
/>
**File size before after (100 DPI vs 500 DPI):**

src="https://github.com/user-attachments/assets/fe21bf79-a18f-4674-bbb5-c99b3d3bd7be"
/>
Sample used was originally 8 MB.
Sample used are attached here:
[image-doc-1.pdf](https://github.com/user-attachments/files/22889873/image-doc-1.pdf)
[image-doc-2.pdf](https://github.com/user-attachments/files/22889876/image-doc-2.pdf)
Strange stuff, I can personally _barely_ tell difference between 500 vs
100 DPI tbh, but the file size difference is very significant.

# Description of Changes
**What was changed**
- Fetch remote HTML content via `HttpClient` before invoking WeasyPrint
to inspect and sanitize input.
- Reject conversions when downloaded HTML contains disallowed `file:`
scheme references (including encoded/obfuscated variants) using a
compiled `Pattern`.
- Write fetched HTML to a secured temporary file and pass that path to
WeasyPrint instead of the remote URL.
- Provide `--base-url` to WeasyPrint so relative resources resolve
correctly while avoiding direct remote fetching as the primary input.
- Add comprehensive unit tests:
- Ensure command invocation uses local temp HTML + `--base-url` and
cleans up temp files.
- Verify redirect with error when disallowed content is detected.
- Cover temp file deletion behavior and error handling paths.
- Improve resource cleanup in `finally` blocks for both temp HTML and
output PDF artifacts.
**Why the change was made**
- Prevents traversal/local file exposure risks by blocking `file:` (and
encoded equivalents) discovered in fetched HTML.
- Reduces attack surface of URL-to-PDF by avoiding direct handing of
remote URLs to the renderer and enabling pre-validation.
- Strengthens deterministic behavior of conversions and improves safety
against SSRF-like vectors.

# Description of Changes
**What was changed**
- Reworked Multi-Tool export to **group page copies per source PDF** and
reuse them during assembly.
- Eliminates repeated embedding of identical resources (fonts, XObjects,
images) that previously occurred when copying pages one-by-one.
- Keeps original vector content whenever possible instead of rasterizing
unchanged pages.
- Minor internal refactor to reduce repeated `copyPages` calls and add
pages from a pre-copied cache.
**Why the change was made**
- Users reported that exporting a PDF via Multi-Tool—without making any
edits—could inflate file size by 5x+.
- Root cause: exporting pages individually caused duplicated resources
in the output document, dramatically increasing size.
- Grouping and reusing copied pages avoids redundant embeddings and
yields output sizes much closer to the original.
Closes#4681

This pull request introduces a new feature that allows users to extract
all embedded attachments from a PDF and download them as a ZIP archive.
The implementation includes backend support for extracting attachments,
a new API endpoint, updates to the service layer, internationalization
for UI strings, and a new web form for user interaction.
**New PDF Attachment Extraction Feature**
_Backend/API:_
* Added a new API endpoint `/api/v1/misc/extract-attachments` in
`AttachmentController` to extract all embedded attachments from a PDF
and return them as a ZIP archive. Returns an error if no attachments are
found.
* Implemented `extractAttachments` method in `AttachmentService` and its
interface to traverse embedded files in the PDF, collect them, and
package them into a ZIP. Handles unique filenames and file metadata.

* Introduced `ExtractAttachmentsRequest` model to handle extraction
requests.
_User Interface:_
* Added a new web form (`misc/extract-attachments.html`) for users to
upload a PDF and download its attachments as a ZIP.
* Created a new web route and controller method to serve the extraction
form.
* Updated navigation menus to include the new "Extract Attachments"
tool.

# Description of Changes
This pull request adds support for converting between PDF and vector
formats (EPS, PS, PCL, XPS) using Ghostscript, including both backend
API endpoints and frontend UI integration. It introduces new
controllers, request models, configuration, and user interface elements
for these conversion features.
### Backend
* Added `PdfVectorExportController` with endpoints for converting PDF to
vector formats and vector formats to PDF, using Ghostscript for
processing.
(`app/core/src/main/java/stirling/software/SPDF/controller/api/converters/PdfVectorExportController.java`)
* Introduced `PdfVectorExportRequest` model to support new conversion
options and parameters.
(`app/core/src/main/java/stirling/software/SPDF/model/api/converters/PdfVectorExportRequest.java`)
* Added a utility method for Ghostscript conversion exceptions.
(`app/common/src/main/java/stirling/software/common/util/ExceptionUtils.java`)
### Configuration
* Registered new endpoints and alternatives for PDF/vector conversion in
the `EndpointConfiguration`.
(`app/core/src/main/java/stirling/software/SPDF/config/EndpointConfiguration.java`)
### Frontend
* Added Thymeleaf templates for "PDF to Vector" and "Vector to PDF"
conversion forms.
(`app/core/src/main/resources/templates/convert/pdf-to-vector.html`,
`app/core/src/main/resources/templates/convert/vector-to-pdf.html`)
* Integrated new conversion tools into the navigation bar and feature
groups.
(`app/core/src/main/resources/templates/fragments/navElements.html`)
* Added controller routes for the new conversion forms.
(`app/core/src/main/java/stirling/software/SPDF/controller/web/ConverterWebController.java`)

# Description of Changes
Fixed getTargetSize to never make an early null return, instead throw an
appropriate customException when the submitted doc has 0 pages.
### Why this change was made:
- If getTargetSize returned null, the call targetSize.getWidth() would
throw a NullPointerException immediately.
- PDDocument.getNumberOfPages() can be 0 e.g., new PDDocument() or a
loader/factory that produced an empty document for a malformed or
partial upload, or a custom pdfDocumentFactory that creates an empty
document in some error paths.
- Replacing the null return with throw
ExceptionUtils.createInvalidPageSizeException("KEEP"): it fails fast
with a clear error instead of producing an NPE.

# Description of Changes
This pull request introduces full support for generating true CBR (Comic
Book RAR) archives from PDF files using the local RAR CLI
### CBR Conversion Implementation:
- Refactored `PdfToCbrUtils.java` to generate image files for each PDF
page, invoke the RAR CLI to create a `.cbr` archive, and clean up
temporary files after conversion..
### Dependency & Endpoint Management:
- Added RAR as a required external dependency in
`ExternalAppDepConfig.java` and checks for its availability, disabling
related endpoints if missing.
- Registered new endpoints under the "RAR" group in
`EndpointConfiguration.java` and updated group validation logic.
### Controller and API Updates:
- Updated the API controller to clarify that the output is a true CBR
archive created with RAR, not ZIP-based.
- Modified the web controller to check for endpoint availability and
return a 404 error if the CBR conversion feature is disabled.

# Description of Changes
This pull request adds support for converting CBR (Comic Book RAR) files
to PDF, optimizes CBZ/CBR-to-PDF conversion for e-readers using
Ghostscript, and improves file type detection and image file handling.
It introduces the `CbrUtils` and `PdfToCbrUtils` utility classes,
refactors CBZ conversion logic, and integrates these features into the
API controller. The most important changes are grouped below.
### CBR Support and Conversion:
- Added the `com.github.junrar:junrar` dependency to support RAR/CBR
archive extraction in `build.gradle`. (https://github.com/junrar/junrar
and https://github.com/junrar/junrar?tab=License-1-ov-file#readme for
repo and license)
- Introduced the new utility class `CbrUtils` for converting CBR files
to PDF, including image extraction, sorting, and error handling.
- Added the `PdfToCbrUtils` utility class to convert PDF files into CBR
archives by rendering each page as an image and packaging them.
### CBZ/CBR Conversion Optimization:
- Refactored `CbzUtils.convertCbzToPdf` to support optional Ghostscript
optimization for e-reader compatibility and added a new method for this.
- Added `GeneralUtils.optimizePdfWithGhostscript`, which uses
Ghostscript to optimize PDFs for e-readers, and integrated error
handling.
### API Controller Integration:
- Updated `ConvertImgPDFController` to support CBR conversion, CBZ/CBR
optimization toggling, and Ghostscript availability checks.

src="https://github.com/user-attachments/assets/5f861943-0706-4fad-8775-c40a9c1f3170"
/>
### File Type and Image Detection Improvements:
- Improved file extension detection for comic book files and image files
in `CbzUtils` and added a shared regex pattern utility for image files.
### Additional notes:
- Please keep in mind new the dependency, this is not dependency-free
implementation (as opposed to CBZ converter)
- RAR 5 currently not supported. (because JUNRAR does not support it)
- Added the new ebook optimization func to GeneralUtils since we'll soon
(hopefully) at least 3 book/ebook formats (EPUB, CBZ, CBR) all of which
can use it.
- Once again this has been thoroughly tested but can't share actual
"real life" file due to copyright.
Closes: #775

# Description of Changes
Explanation on try-with-resource:
> Many resources in Java need be closed after they have been used. If
they are not, the garbage collector cannot reclaim the resources'
memory, and they are still considered to be in use by the operating
system. Such resources are considered to be leaked, which can lead to
performance issues.
>
> Java 7 introduced the try-with-resources statement, which guarantees
that the resource in question will be closed.
>
> try (InputStream input = Files.newInputStream(path)) {
> // "input" will be closed after the execution of this block
> }
>
> This syntax is safer than the traditional method using try, catch, and
finally and hence should be preferred.

# Description of Changes
- **What was changed**
- Reworked `ConvertOfficeController` to use a dedicated temporary
working directory per request and cleaned up with directory-level
deletion.
- Added detection for converter availability via `EndpointConfiguration`
to choose between **unoconvert** and a **soffice** headless fallback.
- Ensured safe filename handling (sanitization, extension checks,
lowercase normalization) and early validation errors for missing/invalid
filenames.
- Switched raw temp file writes to `Files.copy` / `Files.writeString`
with `StandardCopyOption.REPLACE_EXISTING`.
- Implemented robust output handling:
- Verified non-zero exit codes and null results.
- Checked for missing/empty PDF outputs.
- Added fallback lookup for any produced `.pdf` within the work
directory if the expected name is not present.
- Introduced `@Slf4j` logging; improved error and cleanup logging.
- Replaced ad-hoc temp cleanup with `FileUtils.deleteDirectory` for full
working-dir removal.
- Minor imports/cleanup: removed unused `Arrays`, added
`StandardCopyOption`, `FileUtils`, and related imports.
- **Why the change was made**
- Increase conversion reliability across environments where either
unoconvert or soffice may be available.
- Harden security and stability through strict input validation and
sanitized HTML processing.
- Prevent orphaned files/directories and ensure consistent cleanup to
reduce disk footprint and operational issues.
- Provide clearer operational signals (logging, explicit exceptions) for
easier troubleshooting.

# Description of Changes
- **What was changed**
- Added a Spring `@InitBinder` in `StampController` that registers a
`PropertyEditorSupport` for `MultipartFile` to safely handle text inputs
by setting the value to `null`.
- Replaced multiple `switch` statements with modern Java **switch
expressions**:
- Margin selection (`customMargin`) now uses a concise expression.
- Font selection (`alphabet` → font resource path) rewritten as an
expression.
- Position calculations (`calculatePositionX` / `calculatePositionY`)
now return via switch expressions with `yield`.
- Minor readability and maintainability improvements without changing
public API or behavior (besides the binding fix).
- **Why the change was made**
- The `@InitBinder` prevents conversion/binding issues when Spring
attempts to map string form fields to `MultipartFile`, which could cause
exceptions or unexpected behavior in multipart/form-data requests.
- Using switch expressions reduces boilerplate, clarifies intent, and
makes the control flow safer and more maintainable.

# Description of Changes
- **What was changed**
- **URL to PDF flow**
- Changed `ConvertWebsiteToPDF#urlToPdf` to return `ResponseEntity<?>`
and perform a redirect (`303 SEE_OTHER`) back to `/url-to-pdf` with an
`error` query param instead of throwing exceptions.
- Added alert rendering in `url-to-pdf.html` using `param.error` for
localized error display.
- Introduced new translation key `error.invalidUrlFormat` in
`messages_en_GB.properties`.
- **Security / SSRF**
- Migrated `ApplicationProperties.System.UrlSecurity.level` from
`String` to `SsrfProtectionLevel` enum.
- Default now set to `SsrfProtectionLevel.MEDIUM` (`// MAX, MEDIUM,
OFF`).
- This avoids the issue where setting `OFF` returned `false` in
configuration parsing.
- Updated `SsrfProtectionService#parseProtectionLevel` accordingly
(using `level.name()`).
- **Repo hygiene**
- Added `**/LOCAL_APPDATA_FONTCONFIG_CACHE/**` to `.gitignore`.
- **Why the change was made**
- Provide user-friendly, localized error messages instead of exposing
internal exceptions on URL-to-PDF conversions.
- Ensure SSRF protection level parsing is type-safe and consistent—`OFF`
can now be set without yielding a misleading `false` state.
- Prevent unwanted fontconfig cache files from being tracked in Git.

# Description of Changes
- **What was changed**
- Relocated and refactored unit tests:
- `TextFinderTest` and `RedactControllerTest` moved under
`app/core/src/test/...` to align with module structure.
- Expanded test coverage: whole-word vs. partial matches, complex
regexes (emails, SSNs, IPs, currency), international/accented
characters, multi-page documents, malformed PDFs, operator preservation,
color decoding, and performance assertions.
- **API adjustments in redaction flow**:
- `createTokensWithoutTargetText(...)` now accepts the `PDDocument`
alongside `PDPage` to properly manage resources/streams.
- Introduced/used `createPlaceholderWithFont(...)` to maintain text
width with explicit font context.
- **Bug fix in `TextFinder`**:
- Early-return when the (trimmed) search term is empty to prevent
unnecessary processing and avoid false positives/errors.
- Minor cleanup (removed redundant `super()` call) and improved guard
logic around regex/whole-word wrapping.
- **Why the change was made**
- Improve reliability and determinism of PDF redaction and text finding
by exercising real-world patterns and edge cases.
- Ensure structural PDF operators (graphics/positioning) are preserved
during token filtering.
- Prevent crashes or misleading matches when users provide
empty/whitespace-only search terms.
- Align tests with the current project layout and increase
maintainability.

# Description of Changes
This PR introduces several refactorings and minor enhancements across
the `common`, `core`, and `proprietary` modules:
- **Dependency Injection Cleanup**
- Removed unused constructor-injected dependencies (e.g.,
`FileOrUploadService`, `ApplicationProperties`, redundant `@Autowired`
annotations).
- Simplified constructors to only require actively used dependencies.
- **Model Enhancements**
- Added `@NoArgsConstructor` to `FileInfo`, `PdfMetadata`, and
`SignatureFile` to improve serialization/deserialization support.
- **Service Improvements**
- Improved `JobExecutorService` content type retrieval by assigning
`MediaType` to a variable before conversion.
- Enhanced `KeyPersistenceService` with type-safe
`.filter(JwtVerificationKey.class::isInstance)`.
- Annotated `decodePublicKey` in `KeyPersistenceService` with
`@Override` for clarity.
- **Controller & API Changes**
- Updated `AdminSettingsController` to use
`TypeReference<Map<String,Object>>` for safer conversion.
- Improved long log and description strings with consistent formatting.
- **Testing Updates**
- Replaced `.lenient()` mock settings with
`.defaultAnswer(RETURNS_DEFAULTS)` for `FileToPdf` static mocks.
- Used `ArgumentMatchers.<TypeReference<List<BookmarkItem>>>any()` in
`EditTableOfContentsControllerTest` for type safety.
- Updated `UserServiceTest` default `AuthenticationType` from `SSO` to
`OAUTH2`.
- **Formatting**
- Broke up long log/debug lines for better readability.
- Removed redundant `@SuppressWarnings` where type safety was ensured.
These changes aim to make the codebase leaner, more type-safe, and
maintainable, while improving test reliability.
