a basic module for adding a textual watermark to PDFs using Ubercart's file download. This module is appropriate for adding copyright and personalized information to downloadable PDFs.
If your client insists on supporting IE 5, 6 or 7 and they expect PNG transparency, we have a module that might save your day.
OK, what does it do? ¬¬
SuperSleight adds a number of new and useful features that have come from the day-to-day needs of working with PNGs.
Works with both inline and background images, replacing the need for both sleight and bgsleight
Will automatically apply position: relative to links and form fields if they don’t already have position set. (Can be disabled.)
Can be run on the entire document, or just a selected part where you know the PNGs are. This is better for performance.
Detects background images set to no-repeat and sets the scaleMode to crop rather than scale.
Can be re-applied by any other JavaScript in the page – useful if new content has been loaded by an Ajax request.
Can't I just drop it in my theme and call it a day?
-- Yes! If you are comfortable doing theming, you can go ahead and do that.
