Static watermark
Statically defined image overlay
This function will watermark selected images with the same watermark - an image set in the Cloudimage admin console. This is useful for placing your company logo, name, or other copyright information. If you would like to watermark different images with different watermarks, please refer to the Dynamic watermark section.
Step 1. Upload your watermark
Log in to your Cloudimage admin console, navigate to Image Settings / Watermark, and upload your default watermark using the uploader.
Step 2. Start watermarking!
Available parameters
| Parameter | Syntax | Description |
|---|---|---|
use watermark | wat=1 | (required) Activates the watermark function |
watermark position | wat_gravity=X
| Defines the position to "anchor" the watermark to |
watermark scaling (relative to original watermark size) | wat_scale=X
| Watermark image scaling defined in in percent of the watermark dimensions |
watermark scaling (relative to output image size) | wat_scale=Xp
| Watermark image scaling defined in in percent of the output image dimensions |
watermark padding | wat_pad=X[p][,Y[p]]
| Adds padding from the anchoring point in pixels (X) or in percent (Xp) |
watermark opacity | wat_opacity=X
| Defines watermark opacity |
Use watermark
To activate the watermark function, you need to include the wat=1 parameter.
Watermark position
The wat_gravity option sets the position of the watermark (available values are east, northeast, north, northwest, west, southwest, south, southeast, and center/centre) and the wat_pad defines the offset of the watermark from the gravity position.
The padding can be defined in pixels (wat_pad=X[,Y]) or in percent of output size (wat_pad=Xp[,Yp]). The padding is applied after scaling the final image and then it is compressed (see Compression) and delivered via CDN.
Watermark size
The watermark can be scaled relative to the original watermark image (wat_scale=X) or relative to the output image (wat_scale=Xp).
To keep the watermark-to-image proportions for all image resizes, you should use the wat_scale=Xp.
Examples
| Preview | Syntax |
|---|---|
Watermark scaled down to 45% of its original size (1178px), results in 530px watermark: /sample.li/tesla.jpg?w=1400&wat=1&wat_gravity=southwest&wat_scale=45&wat_pad=15 | |
Watermark scaled relative to the output image dimensions (618px watermark): /sample.li/tesla.jpg?w=1400&wat=1&wat_gravity=southwest&wat_scale=45p&wat_pad=15 |
