Notes

Note

From version 14.0.0.5
- a new TNG module is impacted : suggest.php
- location of the "Empty the watermark cache" button is now in Administration >> media - The way a user can ask for a media without watermark is done now via the suggest.php form (Thx to Rob Severijns for the idea!)

Purpose of the Mod

This Mod watermarks your images on the fly and hides their names to prevent image theft. Your original images are not altered.
The watermark is customizable: text, color, tilt, transparency, repetition and font.
[Optional] : Your users can request an unwatermarked copy of the media they are viewing
You can designate some of your users (via Administration/Users) so they can view the media without watermark

Users of the List_Media mod must use the v13.0.1.4 + or 12.2.0.2e + version of watermark in order to see watermarked images on browseyear.php and browseowner.php
Users of the Showfolio mod must use the v13.0.1.4a + version of watermark in order to see watermarked images on showfolio.php

Thanks to

Ron, Philippe, Jean-Louis, Pascal and Alain Evrard for their tests, ideas and comments to realize this first version !
Brent for his inestimable work to take this Mod to an higher level.

Known Problems

With some too large files, you may receive a message "Fatal error: Allowed memory size of ...". Refresh your browser (F5).
If the problem persists, you can try to reduce the number of results during queries ( Administration/Setup/General Settings/Miscellaneous/Max Search Results:). Try to reduce this number...

Parameters

When you change certain settings, it is imperative that you clear the cache of already watermarked media to see the effect of your changes.
To do this, go to Administration >> Media (New in v14.0.0.5) to open your admin_media.php page.
There you will find a link allowing you to empty the cache. This option is only reachable for Administrators. You can also clear the cache files (mods/watermark_mod_cache/) manually.

Parameters:
Text: You can use 2 lines for the watermark. These two lines are separated in the Text parameter by " -x- " (space dash x space dash)

In addition to the common options text, color, transparency, font, owner and proportionality,

If you use the option Angle = "45"
version 1f: A new option allows you to display two lines of watermarks diagonally. The result is NOT guaranteed!
You can determine whether the watermark will be repeated 2 or 3 times on the image.Only the first line of text appears.
If you use the option Angle = "0"
You can use the vpos option to "top" or "bottom". The Repeat option must be imperatively set to "1".
These are the only cases where both lines of the watermark appear.
Repeat on "2" or "3" deletes the second line.
version 1f : you can suppress the possibility of ordering the media without a watermark.

(4) Idem - vpos top - NOT proportioned - (5) Angle 0 - Repeat 3 - Proportioned
