Watermark

Scaleflex DMO (Optimization) can place a watermark on top of your images if you want to protect them from copying or tag them with a serial number or custom text.

There are two types of watermarks:

1. Static watermark: Apply the same image watermark to all the images you decide to watermark (e.g. your company's logo)

2. Dynamic watermark: Specify the watermark in the Scaleflex DMO URL to apply different watermarks to different images.

To activate the watermark function, you need to include the wat=1 parameter.

Available parameters

Parameter	Syntax	Description
use watermark	wat=1	(required) Activates the watermark function
watermark gravity	wat_gravity=X X=[north|south][east|west]|center| absolute|relative	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 positon	wat_pos=X[,Y]	sets the position in percent from the resized image; works only with wat_gravity=absolute and wat_gravity=relative
watermark opacity	wat_opacity=X X=0..1	Defines watermark opacity

Example: //your-token.cloudimg.io/original_image_url/image.jpg?wat=1&wat_gravity=north&wat_text=A%20VERY%20LONG%20TEXT%20WHICH%20WON%27T%20FIT&wat_pad=10&wat_font=Arial-Black&wat_fontsize=20max&wat_color=000

Please note that the watermark cannot be larger than the image - if larger, it is always scaled down first to match the image dimensions.
