Attributes

INPUTFILE
Required. The absolute path to the image you want to apply the watermark to.
Valid File Types: gif / jpeg images
Unix Example:    INPUTFILE = "\var\www\mysite\images\myimage.jpg"
Windows Example: INPUTFILE = "C:\inetpub\www\mysite\images\myimage.jpg"

OUTPUTFILE
Required. The absolute path to the watermarked image that is output by cfx_WaterMark.
Valid File Types: gif / jpeg images
Unix Example:    INPUTFILE = "\var\www\mysite\images\myimage-protected.jpg"
Windows Example: INPUTFILE = "C:\inetpub\www\mysite\images\myimage-protected.jpg"

ALPHA [Default = 30]
Optional. Alpha specifies the degree of transparency of the watermark. 
An Alpha of 1 specifies a completely transparent (not visible) watermark. An alpha of 100 specifies a fully opaque watermark.
Valid entries: integers between 1 - 100. 
Example: ALPHA = "45"

WATERMARKTEXT [Default = empty string]
Optional. The text used to watermark your image. You may combine text and image watermarks on the same image.
To break the text into multiple lines, use the pipe character '|' (located above the backslash on the keyboard) as seen in the example below.
Example: WATERMARKTEXT = "Copyright 2006 MyCompany, Inc."
Example: WATERMARKTEXT = "This is line 1|This is line 2"

FONTFACE [Default = Arial]
Optional. The font face associated with the WATERMARKTEXT.
Note: The availability of font faces will vary depending on your server.  Common fonts are Arial, Courier, Times New Roman and Verdana.
Example: FONTFACE = "Times New Roman"

Optional. The font size associated with the WATERMARKTEXT.
Example: FONTSIZE = "32"

FONTCOLOR [Default = 888888 (medium grey)]
Optional. The hexadecimal equivalent of the RGB color associated with the WATERMARKTEXT.  If you are unfamiliar with
hexadecimal colors, http://www.december.com/html/spec/color.html offers help choosing the right hex value.
Example: FONTCOLOR = "FF0000"

TEXTROTATION [Default = 0 degrees]
Optional. The rotation (in degrees) associated with the WATERMARKTEXT.
Valid Entries: -180 - 180
Example: TEXTROTATION = "45"

TEXTHORIZONTALPOS [Default = center]
Optional. The horizontal(x) position (in pixels) of the WATERMARKTEXT on the INPUTIMAGE.
Valid Entries: Left, Center, Right, Pixel Value
Example: TEXTHORIZONTALPOS = "Right"
Example: TEXTHORIZONTALPOS = "30"

TEXTVERTICALPOS [Default = center]
Optional. The vertical(y) position (in pixels) of the WATERMARKTEXT on the INPUTIMAGE.
Valid Entries: Top, Center, Bottom, Pixel Value
Example: TEXTVERTICALPOS = "Top"
Example: TEXTVERTICALPOS = "30"

FILLTEXT [Default = No]
Optional. This attribute determines whether or not to repeat the WATERMARKTEXT throughout the image.
The spacing between each WATERMARKTEXT is determined by FILLHORIZONTALPADDING and FILLVERTICALPADDING.
Valid Entries: Yes, No
Example: FILLTEXT = "Yes"

FILLHORIZONTALPADDING [Default = 20 pixels]
Optional. The amount of horizontal padding (in pixels) between each repeated WATERMARK.
Example: FILLHORIZONTALPADDING = 40

FILLVERTICALPADDING [Default = 20 pixels]
Optional. The amount of vertical padding (in pixels) between each repeated WATERMARK.
Example: FILLVERTICALPADDING = 40

WATERMARKIMAGE
Optional. The absolute path to an image used as the watermark.  You may combine image and text watermarks on the same image.

Valid Entries: -180 - 180
Example: IMAGEROTATION = "60"

IMAGEHORIZONTALPOS [Default = center]
Optional. The horizontal(x) position (in pixels) of the WATERMARKIMAGE on the INPUTIMAGE.
Valid Entries: Left, Center, Right, Pixel Value
Example: IMAGEHORIZONTALPOS = "Left"
Example: IMAGEHORIZONTALPOS = "50"

IMAGEVERTICALPOS [Default = center]
Optional. The vertical(y) position (in pixels) of the WATERMARKIMAGE on the INPUTIMAGE.
Valid Entries: Top, Center, Bottom, Pixel Value
Example: IMAGEVERTICALPOS = "Bottom"
Example: IMAGEVERTICALPOS = "40"

FILLIMAGE [Default = No]
Optional. This attribute determines whether or not to repeat the WATERMARKIMAGE throughout the image.
The spacing between each WATERMARKIMAGE is determined by FILLHORIZONTALPADDING and FILLVERTICALPADDING.
Valid Entries: Yes, No
Example: FILLIMAGE = "Yes"
