### Property Value

Type: String

The watermark of the thumbnail. Watermark string syntax is described in the Remarks section.

If an empty string is specified, watermark will not be drawn on the thumbnail.

Default value is "".

## Remarks

The watermark string consists of several variables separated with a semicolon:

variable1=value1;variable2=value2;...

The following variables are supported:

Variable | Description
--- | ---
Text | Watermark text. If the text contains semicolon or quotation mark characters enclose it in single (' ') or double (" ") quotes. Moreover, quotation marks (both single ' and double ") inside the text should be escaped with a backslash. For example, to get a Andrew's Photos; Vacation text, set this variable as follows: Text="Andrew\'s Photos; Vacation" Note If both text and image are used as watermarks, the text will always be rendered over the image. Default value is an empty string. When the text watermark is specified, the following parameter also makes sense: FillColor Font Size Style Position OffsetX OffsetY Opacity BackgroundColor BackgroundMarginWidth BackgroundMarginHeight OutlineColor OutlineWidth
FillColor | Font color. It has the same syntax as all Image Uploader color properties (i.e. HTML-style #rrggbb RGB value). Default value is an empty string (the fill is transparent).
Font | Font name. This font should be installed on the client machine. That is why it is highly recommended to use some generic font like Arial, Verdana, etc. Default value is Arial.
Size | Font size (in pixels). Default value is 12.
Style | Font style. The following styles are supported: Bold Italic Underlined You can specify several styles separated with a comma. Example: Style=Bold,Italic Default value is an empty string (regular font is used).
ImageUrl | Url to an image that will be used as the watermark. Note If both text and image are used as watermarks, the text will always be rendered over the image. Default value is an empty string. When the image watermark is specified, the following parameter also makes sense: Width Height Position OffsetX OffsetY Opacity
Width | Width of the image that will be used as the watermark. The image will be resized to the specified dimensions as an ordinary thumbnail, that is, the image can only be downsized, and its proportions are kept. Default value is an empty string (actual image width is used).
Height | Height of the image that will be used as the watermark. The image will be resized to the specified dimensions as an ordinary thumbnail, i.e. the image can only be downsized and its proportions are kept. Default value is an empty string (actual image height is used).
Position | Watermark position. It can take one of the following values: TopLeft - watermark will be drawn in the top left corner of an image. TopCenter - watermark will be drawn in the center of the top of an image. TopRight - watermark will be drawn in the right top corner of an image. CenterLeft - watermark will be drawn in the center of the left edge of an image. Center - watermark will be drawn in the center of an image. CenterRight - watermark will be drawn in the center of the right edge of an image. BottomLeft - watermark will be drawn in the bottom left corner of an image. BottomCenter - watermark will be drawn in the center of the bottom of an image. BottomRight - watermark will be drawn in the bottom right corner of an image. Default value is BottomRight.
OffsetX | Horizontal offset (in pixels) of the watermark relative to the position it is anchored to (according to the Position variable). Note If horizontal position is left or center, coordinates direction is left-to-right. If it is right, coordinates direction is flipped to right-to-left. Default value is 0 (no offset).
OffsetY | Vertical offset (in pixels) of the watermark relative to the position it is anchored to (according to the Position variable). Note If vertical position is top or center, coordinates direction is top-to-bottom. If it is bottom, coordinates direction is flipped to bottom-to-top. Default value is 0 (no offset).
Opacity | Watermark opacity percentage. If 0, the watermark is totally transparent. If 100, the watermark is opaque. Values between 0 and 100 will produce watermark with various level of transparency. This value works for all elements of watermark. There is no way to configure different opacity for background, text outline and text fill. Default value is 100.
BackgroundColor | Background color. It has the same syntax as all Image Uploader color properties (i.e. HTML-style #rrggbb RGB value). Default value is an empty string (the background is transparent).
BackgroundMarginWidth | Width of additional space outside of the watermark filled with background (in pixels). Default value is 0.
BackgroundMarginHeight | Height of additional space outside of the watermark filled with background (in pixels). Default value is 0.
OutlineColor | Text outline color. It has the same syntax as all Image Uploader color properties (i.e. HTML-style #rrggbb RGB value). Default value is an empty string (the outline is transparent).
OutlineWidth | Width of the text outline. Default value is 1.

Note

The watermark string is case insensitive.

Though you can set both image and text watermarks at the same time, it makes sense to use only one of them. For text watermarks the only required variable is Text. Here is an example of watermark string which will draw green semi-transparent italic text Aurigma in the bottom left corner of an image:

### JavaScript

    thumbnailWatermark: 'Text=Aurigma;Opacity=75;FillColor=#00ff00;Position=BottomLeft;Style=Italic;Size=30'

For image watermarks ImageUrl, Width, and Height are required. Here is an example of semi-transparent logo drawn in the top tight corner of the image:

### JavaScript

    thumbnailWatermark: 'ImageUrl=http://localhost/watermark.png;Width=86;Height=63;Position=TopRight;Opacity=50'

This property makes sense only if the mode property has the Thumbnail value.
