Watermarking Parameters
You can provide both an image and text for your watermark. The position of the text can be set in the properties. You can provide just the image or just the text. Or a combination of the two.
Visible Image
As a watermark image you can use most common pixel image formats, e.g. JPEG, PNG, and TIF. If an animated image file is supplied, the first frame will be used as the watermark image. You can either type in or browse to find the watermark image file.
You define the opacity of the watermark from 0 to 100. If you set the opacity to 0, the watermark image will be totally transparent and you will not be able to see it. If you set it to 50, the watermark will be semi-transparent. The watermark will be completely opaque (solid) if the opacity level is set to 100.
Under Image Position, you define the area where the watermark image should be placed. The position of the watermark image within the resulting image is defined by anchor points.
You can control the size of the watermark image by scaling it. When scaling, proportions are constrained, and the images will be scaled to provide the maximum overlay. Small watermark images will be enlarged and large ones will be made smaller. You can also define to have only small images enlarged. Following scaling options are available:
At long edge – The watermark image is scaled at its long edge. The long edge will be scaled to fit the source image and with proportions constrained the short edge will be scaled accordingly.
At short edge – The watermark image is scaled at its short edge. The short edge will be scaled to fit the source image and with proportions constrained the long edge will be scaled accordingly.
Fit to image size – The watermark image is scaled to fit the size of the image, depending on the image orientation (portrait or landscape).
Scale up only – A watermark image that is smaller than the source image is enlarged to provide the maximum overlay. Proportions are constrained.
NOTE: If you do not activate the scale option, watermark images larger than the source image will be cropped.
The Previously selected image field will display an image only if the watermarking parameters are defined for an Asset Action. Then the watermarking image will be provided by the Cumulus Server and the field displays a preview of the image that was transferred by the Cumulus Server.
Visible Text
The visible text can be entered by you and/or taken from a Cumulusrecord field. Using a record field enables you to have individual watermarks when batch processing images.
To include a record value as text, select the desired field from the Record field drop-down list and click Append. The corresponding placeholder entry will be inserted at the end of the Content field.
You are allowed to enter multiple lines of text in the Content field. Enter \n for carriage return. You can also type special characters (like ©, ®, etc.). They will be rendered properly in the processed images.
You can control the position of the text. You can specify the Horizontal Position (Left, Center, and Right) and Vertical Position (Top, Middle, and Bottom) of the text.
You define the opacity of the watermark from 0 to 100. If you set the opacity to 0, the watermark will be totally transparent and you will not be able to see it. If you set it to 50, the watermark will be semi-transparent. The watermark will be completely opaque (solid) if the opacity level is set to 100.
You can choose the font, style, size and color of the text. To have the text fit best to the image size independently of the font size setting, activate the Fit text to image size option.
Under Text Position, you define the area where the watermark text should be placed. The position of the text within the resulting image is defined by anchor points.
Employing Custom Record Fields
The drop-down list for selecting a record field displays the Cumulus standard fields only. If you want to include a custom field, you must enter the GUID (Globally Unique Identifier) of the field into the Content field of the Watermark AsssetProcessor Parameter dialog.
To find out the GUID open the Properties of the field (  Cumulus /  Edit > Preferences > Catalog Settings) and on the General tab double-click the field name of the field Field Name.
This copies the GUID to the clipboard and you can paste it. A Cumulus GUID is composed of exactly 38 characters and looks like this:
