Minimal watermark font size

We are using the Watermark Java api and we noticed that the watermark text size cannot be set smaller than 10px. Is this a known defect, or is there any workaround that can set the warkmark font size smaller, such as 5px?

We couldn’t reproduce this issue using following code and API version 20.5:

com.groupdocs.watermark.licensing.License lic = new com.groupdocs.watermark.licensing.License();
lic.setLicense("license file path here");
Watermarker watermarker = new Watermarker("D:\\source.docx");    
TextWatermark watermark = new TextWatermark("top secret", new Font("Arial", 3));                                                                                
watermarker.add(watermark);                                                                     "D:\\output.docx");                                                                        

Please have a look at this screenshot (2).PNG (63.7 KB). Different font sizes are tested (e.g. 100, 10, 3) and all are working. Please download/clone this open-source console application and let us know if issue persists.


We could reproduce this issue when horizontal, vertical alignments along-with few other Watermark properties are set. Hence, it’s been logged in our internal issue tracking system with ID WATERMARKJAVA-86. You’ll be notified about the outcomes.
