Social Group and Album Enhancements - Watermark Generator

Quick Info

This mod adds a watermark to album and attachment images.
The watermark is customizable via image files or specified text.
Processed images are cached and the original files remain untouched, so you can modify or remove the watermark anytime you want.


Features

- Intelligent Caching
- Uses standard vBulletin methods, therefore no file modifications necessary
- Settings-Preview with a sample image in Adminpanel
- Generative plugin behaviour, works with most other mods which use the same hooks or use attachment images elsewhere

Installation

Step 1)

Upload files inside upload directory according to their structure:

> forum root
	> admincp
		+ pl_watermark_admin.php
	> images
		> misc
			+ plwm_sample.jpg
	> includes
		> cron
			+ pl_watermark_cron.php
		> xml
			+ cpnav_plwatermark.xml
		+ pl_watermark_functions.php
		+ pl_watermark_imagemanipulation.php


Step 2)

Import "product-plwatermark.xml" as addon into your vBulletin AdminCP


Step 3)

Navigate in your vBulletin AdminCP to PL Watermark Generator -> Plugin Settings.
Define the settings how you see fit. The options should be self-explanatory, if you need help with certain things, ask in the modification thread.

Additional Info

The Mod is currently in BETA. This means, that we tested it on a test environment (vb 4.0.x to 4.1.3) but has not yet undergo excessive stress test.
Keep an eye out for updated versions until the final release!
If you encounter any bugs, missing or misplaced features, let us know!

F.A.Q

- I don't see changes in my live images!
> To see changes on the image files you have to clear your browser's cache!
In firefox it's enough to force a fresh reload via STRG+F5 and on other browsers STRG+F5 or SHIFT+F5 should work.
If you don't perform this step, your browser will show the old cached version and maybe the watermark won't show or changes won't apply.

- My png/gif watermark isn't transparent, instead I get a black background!
> PNG-8 is known for having transparency problems, GIF in some cases as well.
Fall back to PNG-24 with Alpha channel (all modern image tools should be able to save as PNG-24)
If you have trouble creating a working png-24 with alpha channel, you can send me a PM with a link to your watermark and I'll convert it to png-24 for you.

- I have trouble with special characters or non-latin charactersets!
> The addon is using standard php functionalities for the text. If for any reason you have trouble with special chars, I suggest using a transparent png-24 with the text from an external image tool instead.

Problem with the png image, it looks completely black the rectangule of the image in the watermarked images.

v 4.1.2.

I am trying to test with text, but I prefer image watermark. with text, is it possible to put a % of the size of image instead of the size of the text? (because perhaps it was 300 px image and 1024 px other, so it´s difficult to give only one text size.

Thanks, great mod,

@Dr.osamA:

Did you test the settings via preview first? Is the watermark rendered on the sample image?
Try the steps below so we can find out why your attachments aren't displayed.

@TEMPESTADE, inigo:

Is it possible that you don't have the GD lib installed?


To all others where the attachment doesn't show:
You can upload the testattachments.php file from this post into your forum root dir.
Then navigate to the file via browser and add the parameter i1 to it so it looks like this:

http://someforum.tld/forum/testattachments.php?i1=13

Replace 13 with any image id which is big enough so the watermark should be displayed!
Now if any errors occur, the script will output them, other than the attachment.php which disables error reporting completely. This way it's easier for me to pinpoint the problem.

The GD lib is correctly running (I use it in vbgallery too:

GD Support 	enabled
GD Version 	2.0 or higher
FreeType Support 	enabled
FreeType Linkage 	with freetype
FreeType Version 	2.3.7
T1Lib Support 	enabled
GIF Read Support 	enabled
GIF Create Support 	enabled
JPG Support 	enabled
PNG Support 	enabled
WBMP Support 	enabled

The image appears in the correct place, with correct size, but is a black rectangule. Any other idea?

Thanks,

Thanks,

Did you use a .png or a .gif for the watermark?
Did you set the alpha channel correctly?
If png: Is it a 8-bit png or a 24-bit png?

I attached a test image from which i know that the watermark generator can display. Can you test it out and tell me if it's applied correctly or has a black background too?

working on everything but cms article pages. works on promoted articles but mot ones created just for the front page and not originating from the forum.
cms/content.php/

I have been testing, and the problem appears to be the PNG8, because the same image saved as PNG-24 is working.

Your test image was ok, but with no trasparency.

So the problem is solved, PNG-24 working, but I have to do more tests, because there are some of the images without watermark,... and I think is because the browser's cache.

so I will tell you when I can test deeply,

Thanks,
