Watermarks
Print2Flash can apply watermarks to document pages. A watermark is text or an
image that appears above existing document content, similar to a stamp. For
example, you might want to apply a “Confidential” watermark to pages with
sensitive information.
You may control watermark creation in the
Watermark tab of Document Options window at manual conversion
or with WatermarkImage, WatermarkScale and WatermarkTransparency properties of
Profile
object or with WatermarkImage, WatermarkScale and WatermarkTransparency options of
Enhanced Batch Processing at
programmatic conversion.
When configuring a watermark you need to choose an image file of PNG format in
the Watermark Image field. This image is placed at the center of each document
page above document content.
Image size is controlled by the "Scale relative to page size" field where you
need to enter the image size expressed in percentage relative to page size. The
image is scaled so as to fit the specified percentage of page width or height
(whichever is smaller) without image distortion. Higher values make watermark
image appear bigger while lower values makes it smaller. For example, if this
value is set to 100 percent, the image is scaled so as to fit page width or
height (whichever is smaller) and image touches page edges. Smaller values
reduce image size so that image does not touch page edges.
Your watermark image file may contain transparency (alpha channel) so that it
does not obscure the document contents below the watermark. You may create such
transparency yourself when authoring your watermark image in a graphic editor or
Print2Flash may assist you in this by correcting the transparency of your image.
This can be achieved with Transparency Correction field. This field can accept
values from 0 to 255. 0 value means transparency of the image is not affected.
255 means image is fully transparent (not visible). Intermediate values
correspond to various degrees of transparency.
