Watermark image
Support JPG, PNG, and GIF formats (dynamic GIF images will be converted to static, displaying only the first frame), with an image size of less than 2MB.

Display size
By default, the image will be displayed in its original size. For images that are too large or too small, you can adjust the display area. After the adjustments are completed, the image will be proportionally scaled and displayed in the center within the designated size area.
The original image size is 2000 x 1000. To avoid distortion and prevent the image from covering the entire chart, you can set the image to display as a 200 x 100 image in the report.
Rotation & transparency

Rotation: Support -360 to 360 degrees, with the horizontal 3 o'clock position as 0 degrees. Positive values represent clockwise rotation, while negative values represent counterclockwise rotation.

Other Notes
If the edition in use does not support variables or the variable parsing fails, the variable part will be displayed as empty (for example, "Viewer{{viewer}}" will show as "Viewer" if the variable "viewer" cannot be parsed).
After the page is shared, variables related to the user identity, including the user UIN, cannot be read. Therefore, if the watermark contains variables for the visitor identity information, the variables will fail to parse. However, the creator information can still be parsed.
Push notifications will not display watermarks in screenshots.
