Static watermark

Statically defined image overlay

This function will watermark selected images with the same watermark - an image set in the Asset Hub. 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 in the Asset Hub

Log in to your Filerobot Asset Hub and navigate to Settings / Process -> Images / 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 X=[north|south][east|west]|center	Defines the position to "anchor" the watermark to
watermark scaling (relative to original watermark size)	wat_scale=X X=0..100	Watermark image scaling defined in in percent of the watermark dimensions
watermark scaling (relative to output image size)	wat_scale=Xp X=0..100p	Watermark image scaling defined in in percent of the output image dimensions
watermark padding	wat_pad=X[p][,Y[p]] X/Y=0..100[p]	Adds padding from the anchoring point in pixels (X) or in percent (Xp)
watermark opacity	wat_opacity=X X=0..1	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[,Y]) or relative to the output image (wat_scale=Xp[,Yp]).

To keep the watermark-to-image proportions for all image resizes, you should use the wat_scale=Xp[,Yp].
