+- description: Learn how to watermark diagram pages java with GroupDocs.Watermark.
+    This step‑by‑step guide covers setup, implementation, and best practices for secure
+    diagram handling.
+  name: How to watermark diagram pages java using GroupDocs.Watermark
+  steps:
+  - name: load your diagram
+    text: The `DiagramLoadOptions` class configures how a diagram file is read into
+      memory. Provide the source file path and any format‑specific options you need.
+  - name: initialize the text watermark
+    text: '`TextWatermark` represents a text overlay that can be applied to documents.
+      Create a `TextWatermark` instance with the desired text, font, color, and rotation.
+      This object defines the visual appearance of the overlay.'
+  - name: add the watermark to the diagram
+    text: The `Watermarker` class orchestrates the watermarking operation. Use the
+      `add` method to apply the `TextWatermark` to all background pages of the diagram.
+  - name: save and close
+    text: '`save` writes the modified document to the specified output path. `close`
+      releases the underlying file resources. Call `save` on the `Watermarker` instance
+      to write the watermarked diagram to disk, then release resources with `close`.
+      This ensures the file handle is released promptly.'
+  type: HowTo
+- questions:
+  - answer: Yes, the library fully supports SVG, VSDX, and other vector diagram formats,
+      preserving scalability after watermarking.
+    question: Can GroupDocs.Watermark handle vector formats like SVG?
+  - answer: Absolutely. Use the `add` method overload that accepts a page range or
+      a `PageCollection` to target specific pages.
+    question: Is it possible to watermark only selected pages?
+  - answer: The `remove` API scans for matching watermark signatures and deletes them,
+      allowing you to restore the original diagram without re‑uploading.
+    question: How do I remove a watermark that was previously added?
+  - answer: When you save the watermarked diagram as PDF, the overlay is baked into
+      the PDF pages, making it permanent across viewers.
+    question: Does the watermark survive PDF conversion?
+  - answer: Each watermark is rendered in the order added; you can stack text and
+      image watermarks for layered branding.
+    question: What happens if I apply multiple watermarks?
