| Hook places a watermark on the document as it is displayed. This hook is implemented based on the definition of the ReadFileHookAdapter system hook, which allows to change the binary stream of the displayed document from archive or in preview in the process. Configuration of the watermark insert hook is defined in JSON format as a list and is managed by the PCM (Plugin Configuration Manager). A watermark is placed on every page of the document and accepts only PDF format. |

documentClassId* | 1.0.0 | The document class id indicates for which documents the watermark insertion parameters are to be considered. | Integer | | type* (watermark) | 1.0.0 | Specifies what type of watermark is. | Text | | Value | MeaningDescription |
|---|
| BARCODE | Encodes the value of the text parameter into a barcode with the specified format defined in the format parameter. The watermark on the document is a barcode. | | TEXT | The value of the text parameter is applied to the document as an explicit, unencoded watermark. |
| text* (watermark) | 1.0.0 | Takes the text value that is used to create the watermark. In order to use document index values, the index id should be enclosed in curly braces {}. It is possible to use more than one index value in a parameter. Each subsequent index must be followed by curly braces. Example.: Case number: "{8}, Registration Date {9}" Watermark text -> Case number: 433589, Registration Date: 13-02-2021
It is also possible to use special keywords that return information about the user, process id and activity id. All available values are listed in the next column. Example: "Username: {USER_NAME}, Date: {CURRENT_DATE}" Watermark text -> "Username: admin, Date: 2022-10-21"
| Text | | Warning |
|---|
Any typed index ids in the text string must exist in the document class specified by the documentClassId parameter. If the document being viewed does not contain an index value (it is empty) whose id is given in curly braces in this parameter, the id will be replaced with the empty string "". |

| alignment* (watermark) | 1.0.0 | Specifies relative to which of the four corners of the document page the position of the watermark will be calculated based on the positionX% and positionY% parameters. More information... | Text | Pay attention to the corresponding values of the positionX% and positionY% parameters, because depending on the value of the alignment, anchor parameter, and the size of the watermark, the watermark may extend beyond the document page, i.e. be partially or completely invisible. | ValueAvailable values | Meaning |

| positionX%* (watermark) | 1.0.0 | Indicates the X (horizontal) position of the watermark in percent relative to the document page dimensions. The position is set based on the selected page corner in the alignment parameter. | Integer | Value between 0 and 100. | positionY%* (watermark) | 1.0.0 | Indicates the Y (vertical) position of the watermark in percent relative to the document page dimensions. The position is set based on the selected page corner in the alignment parameter. | Integer | Value between 0 and 100. | opacity* (watermark) | 1.0.0 | Specifies the transparency degree of visibility of the inserted watermark on the pages of the document. | Float | The element is fully transparent (invisible). .0 and 1.0.format* The item is partially transparent. The element is fully opaque (uniform). | clockwiseAngle* (watermark) | 1.0.0 | Watermark rotation. | Float | | format* (watermark.watermarkBarcode) | 1.0.0 | Specifies standard for one-dimensional barcodes (writing information on one line, in the form of dashes). | Text | | Value | Meaning |

| CODE_39 | Also known as "USS Code 39", "Code 3/9", "Code 3 of 9", "USD-3", "Alpha39") - fixed-width alphanumeric single character bar code. | | CODE_93 | Code 93 was designed as an improvement to the Code 39 encoding. Like its original in the basic version, it is able to store 43 alphanumeric characters. However, compared to its predecessor, it has 4 additional control characters. | | CODE_128 | High-resolution alphanumeric one-dimensional barcode. It was designed to encode 128 ASCII characters |
| the barcode format.

Method 1 - (obsolete) rotation is based on the basic functions of the library. The rotation for the barcode watermark is counterclockwise. Method 2 (recommended) - rotation takes place relative to the watermark point specified in the anchor property. The rotation is clockwise for the barcode watermark. The parameter is optional. By default, METHOD_1 is used. | Text | | Available values |

The value of this parameter is taken into account after JSON deserialization (after entering the correct names and values of JSON configuration parameters in PCM), hence if an error occurs during the deserialization stage, the default BLOCK error handling will be used. |

The resulting file has no security compared to its original version. The parameter does not take into account the removal of the file password that was used to prevent the file from being opened. | Boolean | Optional, when undefined, defaults to false for backward compatibility. |

Code_128 | Variable length, high density alphanumeric code. It can encode characters from the entire ASCII range. The coding uses a dash and a gap of four possible widths, which makes it a compact code. Code 128 can be scanned in either direction and there is no limit to the length of the code itself.
