| 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. |

|---|
| Parameter name in JSON configuration | From version | Description | Paremeter type | Comments and restrictions |
|---|
documentClassId* | 1.0.0 | The document class id indicates for which documents the watermark insertion parameters are to be considered. | Integer | | watermark type* | 1.0.0 | Specifies what type of watermark is. | Text | | Value | Meaning |
|---|
| 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. |
| watermark text* | 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 | Text | | Warning |
|---|
Any typed index ids in the text string must exist in the document class specified by the documentClass 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 "". |
| watermark positionX%* | 1.0.0 | Indicates the X (horizontal) position of the watermark in percent relative to the document page dimensions. | Integer | Value between 0 and 100. | watermark positionY%* | 1.0.0 | Indicates the Y (vertical) position of the watermark in percent relative to the document page dimensions. | Integer | Value between 0 and 100. | watermark opacity* | 1.0.0 | Specifies the transparency of the inserted watermark on the pages of the document. | Float | Value between 0.0 and 1.0. | watermark alignment* | 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. | Text | | Value | Meaning |
|---|
| TOP_LEFT | The position of the watermark in relation to the top left corner. 
| | TOP_RIGHT | The position of the watermark in relation to the top right corner. 
| | BOTTOM_LEFT | The position of the watermark in relation to the bottom left corner. 
| | BOTTOM_RIGHT | The position of the watermark in relation to the bottom right corner. 
|
| watermark anchor* | 1.0.0 | Specifies the position of the watermark in relation to the corresponding corner of the watermark. | Text | | Value | Meaning |
|---|
| BOTTOM_LEFT | The position of the watermark in relation to the lower left corner of the watermark. 
|
| watermark watermarkBarcode format | 1.0.0 | Specifies standard for one-dimensional barcodes (writing information on one line, in the form of dashes). | Text | | Value | Meaning |
|---|
| CODE_39 | Barcode with variable-length alphanumeric characters to store 43 different characters. Each sign consists of 9 elements (light and dark bars), 3 of which are significantly wider. This format allows you to encode numbers, capital letters and characters (-, ., (Space), $, /, +,%, *). Char | Value | Char | Value | Char | Value | Char | Value |

| | CODE_93 | The barcode is an improvement of the CODE_39 format. Like its prototype, it stores 43 alphanumeric characters, but additionally has 4 control characters (($), (%), (/), (+)).
The code accepts only uppercase letters. Char | Value | Char | Value | Char | Value | Char | Value |

| | CODE_128 | Variable length, high density alphanumeric code. It can encode characters from the entire ASCII range. 
|
| watermark watermarkBarcode codeWidth | 1.0.0 | Defines the width of the barcode in pixels. | Integer | The parameter does not define the maximum width of the barcode - in the case when the substituted value turns out to be too long, the width will be automatically increased. | watermark watermarkBarcode codeHeight | 1.0.0 | Defines the height of the barcode in pixels. | Integer | | watermark watermarkText size | 1.0.0 | Text size. | Float | | watermark watermarkText encoding | 1.0.0 | Character encoding. | Text | | Value | Meaning |

| CP1250 | A code page for the representation of texts in Central European languages using the Latin alphabet, for example Albanian, Croatian, Czech, Polish, Romanian, Slovak, Slovenian, Hungarian. | | CP1252 | A code page to represent texts in Western European languages. | | CP1257 | A code page used to represent texts in Estonian, Lithuanian or Latvian. This set is largely compatible with ISO 8859-13, and is suitable for coding the Polish language. | | MACROMAN | Character encoding mainly used in classic Mac OS to represent text. It encodes 256 characters, the first 128 of which are identical to ASCII and the remaining characters include math symbols, diacritics, and additional punctuation marks.
