# Description of Changes
Please provide a summary of the changes, including:
This pull request introduces the "Fake Scan" feature, which simulates
scanned PDFs with customizable settings. The changes include the removal
of a work-in-progress controller, the addition of a new request model,
and updates to the frontend to support the feature.
### Backend Changes:
* **Removed the unfinished `FakeScanControllerWIP`:** The entire
`FakeScanControllerWIP` class, which contained unimplemented and
experimental code for processing PDFs, has been removed. This cleanup
eliminates unused code and dependencies. Some of the original code of
removed file was ported to the new Controller.
* **Added `FakeScanRequest` model:** Introduced a new model class
`FakeScanRequest` to handle input parameters for the "Fake Scan"
feature. It includes fields for file input, quality, rotation,
colorspace, and other advanced settings, with validation and default
values.
### Frontend Changes:
* **Localization updates for the "Fake Scan" feature:** Added new
localization keys for the "Fake Scan" feature, including titles,
descriptions, and advanced settings options like quality, rotation, and
colorspace.
* **Added "Fake Scan" card to the homepage
### Pictures:
Front-end

Example document (based on defaults; can be drastically changed
according to need.):

### Quirks/known issues
- Performance: It might take even reasonable hardware to convert bigger
pdf >500KB more than a few minutes.
- Yellowish filter applies to the whole document and also incl to the
background. (not desirable in some instances)
- There is some randomness involved in the default preset, helps imitate
scan but some user might find it annoying. (but it can be disabled
through advanced settings).
- Some features might confusing to people with no additional context.
Closes#458

- **What was changed**
- Replaced Tibetan locale code in README (`README.md`) from `zh_BO` to
`bo_CN`.
- Renamed resource file `messages_zh_BO.properties` to
`messages_bo_CN.properties` and updated its internal keys/translations.
- Updated the HTML fragment (`templates/fragments/languages.html`) to
reference `bo_CN` instead of `zh_BO`.
- Added a `[bo_CN]` section in `scripts/ignore_translation.toml` and
expanded ignore rules across multiple language sections to cover
additional codes.
- Enhanced `counter_translation.py` error handling: now catches
`ValueError` as `e` and logs file path and line number for easier
debugging.
- **Why the change was made**
- The proper locale identifier for Tibetan is `bo_CN`, aligning with
[Localizely’s standard](https://localizely.com/locale-code/bo-CN/).
- Ensures consistency across code, resources, and templates so the
Tibetan translation loads correctly.
- Expanded ignore lists prevent false positives in translation coverage
checks, and improved error logging aids maintenance of the translation
scripts.

# Description of Changes
Please provide a summary of the changes, including:
- **What was changed**
- **EmailController**: Added a `catch (MailSendException)` block to
handle invalid-address errors, log the exception, and return a 500
response with the raw error message.
- **EmailServiceTest**: Added unit tests for attachment-related error
cases (missing filename, null filename, missing file, null file) and
invalid “to” address (null or empty), expecting `MessagingException` or
`MailSendException`.
- **MailConfigTest**: New test class verifying `MailConfig.java`
correctly initializes `JavaMailSenderImpl` with host, port, username,
password, default encoding, and SMTP properties.
- **EmailControllerTest**: Refactored into a parameterized test
(`shouldHandleEmailRequests`) covering four scenarios: success, generic
messaging error, missing `to` parameter, and invalid address formatting.
- **Why the change was made**
- To ensure invalid email addresses and missing attachments are handled
gracefully at the controller layer, providing clearer feedback to API
clients.
- To improve overall test coverage and guard against regressions in
email functionality.
- To enforce correct mail configuration via automated tests.

## Summary
- allow tests to spy on PipelineProcessor web requests
- fix ResponseEntity usage in PipelineProcessorTest
## Testing
- `./gradlew test --offline` *(fails: No route to host while downloading
gradle-8.14-all.zip)*
# Description of Changes
Please provide a summary of the changes, including:
- **What was changed:**
- Refactored the `updateUserSettings` method in `UserController` to
accept a `@RequestBody Map<String, String>` named `updates` instead of
pulling parameters from `HttpServletRequest`.
- Removed the now-unused `HashMap` import and the manual
parameter-extraction loop.
- **Why the change was made:**
- **Bug Fix:** The previous implementation relied on
`request.getParameterMap()`, which was consistently empty, so no
settings were ever applied.
- Simplifies controller logic by leveraging Spring’s request-body
binding.
- Improves readability and maintainability, removing boilerplate and
error-prone code.

# Description of Changes
- **What was changed**
- Updated controller methods to use strongly‐typed primitives (`int`,
`long`, `boolean`) instead of `String` for numeric and boolean
parameters, eliminating calls to `Integer.parseInt`/`Long.parseLong` and
improving null‐safety (`Boolean.TRUE.equals(...)`).
- Enhanced all API request model classes with richer Swagger/OpenAPI
annotations: added `requiredMode`, `defaultValue`, `allowableValues`,
`format`, `pattern`, and tightened schema descriptions for all fields.
- Refactored HTML form templates for “Remove Blank Pages” to include
`min`, `max`, and `step` attributes on numeric inputs, matching the
updated validation rules.
- **Why the change was made**
- **Type safety & robustness**: Shifting from `String` to native types
prevents runtime parsing errors, simplifies controller logic, and makes
default values explicit.
- **Better API documentation & validation**: Enriching the Swagger
annotations ensures generated docs accurately reflect required fields,
default values, and permitted ranges, which improves client code
generation and developer experience.
- **Consistency across codebase**: Aligning all request models and
controllers enforces a uniform coding style and reduces bugs.

Potential fix for
[https://github.com/Stirling-Tools/Stirling-PDF/security/code-scanning/11](https://github.com/Stirling-Tools/Stirling-PDF/security/code-scanning/11)
To fix the issue, we should avoid using `innerHTML` to insert untrusted
data into the DOM. Instead, we can use DOM manipulation methods like
`createElement` and `appendChild` to construct the required HTML
structure safely. These methods do not interpret strings as HTML,
thereby mitigating the risk of XSS.
Specifically:
1. Replace the `innerHTML` assignment on line 302 with code that creates
the required DOM elements programmatically.
2. Ensure that the `selectedOperation` value is inserted as plain text
using `textContent` or equivalent methods.

## Refactor: Improve clarity of permission variable names
Renamed confusing `can[Action]` boolean variables to `prevent[Action]`
(e.g., `canPrint` -> `preventPrinting`) in `PasswordController.java`,
`AddPasswordRequest.java`, and `add-password.html`.
The previous `can[Action]` convention was misleading, as `true` meant
the action was *disallowed*. The new `prevent[Action]` naming directly
reflects the intent (`true` = prevented), improving code clarity.
**Changes:**
* Updated variable names in controller logic
* Updated `@Schema` descriptions in `AddPasswordRequest.java`
* Updated corresponding HTML element attributes (`id`, `name`, `for`) in
`add-password.html`
**Important Notes:**
* The underlying logic still inverts the boolean when setting
permissions (e.g., `AccessPermission.setCanPrint(!preventPrinting)`).
* User-facing UI text remains unchanged per request of @Frooodle in
#3420.
**Why not invert the API logic**
* Inverting API (to can[action] logic) would either invalidate the UI
* Inverting API AND changing UI would warrant bigger translation effort
to change it in all languages
* This version is consistent (meaning what the UI says is actually done)
and preserve the UI language (meaning no translations needed) however it
is inconsistent with PDFBox methods naming scheme
**PDFBox**
* **PDFBox Interaction:** This refactor addresses the naming *within*
Stirling-PDF's API and Front-end layers only. The controller logic
intentionally inverts the `prevent[Action]` boolean
(`ap.setCanPrint(!preventPrinting)`) to correctly interact with the
underlying PDFBox methods. No further renaming related to these
permissions is necessary as the PDFBox methods themselves retain the
`can[Action]` names.
Underlying logic is not changed so it should work but just in case I
tested locally on an Adobe PDF that contained form in Chrome.

Potential fix for
[https://github.com/Stirling-Tools/Stirling-PDF/security/code-scanning/224](https://github.com/Stirling-Tools/Stirling-PDF/security/code-scanning/224)
To fix the issue, we should avoid assigning untrusted data directly to
`innerHTML`. Instead, we can use `textContent`, which safely sets the
text content of an element without interpreting it as HTML. This ensures
that any special characters in the `data-title` attribute are treated as
plain text, preventing XSS attacks.
The fix involves replacing `tabButton.innerHTML = title;` on line 12
with `tabButton.textContent = title;`. This change ensures that the
`title` is safely rendered as text.

# Description of Changes
Please provide a summary of the changes, including:
- **What was changed**
- Updated `SignPDFWithCertRequest` to use `Boolean` for `showSignature`
and `showLogo`, and made `pageNumber` nullable.
- In `CertSignController`:
- Added an `@InitBinder` to convert empty multipart fields to `null`.
- Extended `@PostMapping` to consume both `multipart/form-data` and
`application/x-www-form-urlencoded`.
- Wrapped `pageNumber` calculation in a null-check (`pageNumber =
request.getPageNumber() != null ? request.getPageNumber() - 1 : null`).
- Changed signature-visualization and logo checks to
`Boolean.TRUE.equals(...)` to avoid unboxing NPE.
- Cleaned up imports and schema annotations in the request model.
- **Why the change was made**
- Prevent a 500 Internal Server Error caused by calling `.intValue()` on
a null `pageNumber` when `showSignature=false` (invisible signatures).
- Ensure that omitting `pageNumber` doesn’t break clients using the “try
it out” swagger UI or `curl`-based requests.
- **Any challenges encountered**
- Configuring Spring’s data binder to treat empty file inputs as `null`
required a custom `PropertyEditorSupport`.
- Balancing backward compatibility with stricter type handling
(switching from primitive `boolean` to boxed `Boolean`).
Closes#3459
