Permanent Watermark with GD2

[Nibbler]

You should be able to use the is_image() function to check if the file is an image, and only apply the watermark if it is.

Hi. I've applied this hack to all of the instructions but I get the following error when I do the watermark action.

Fatal error: Unsupported operand types in /home/badak/public_html/mrbadak/include/picmgmt.inc.php on line 320

the line 320
$src_x = $srcWidth - ($logoW + 5);

is this problem with my server settings? how do i check?

path of your server has changed, change it to right value

I was unable to modify my original post and I do think that the top post should be the newest version. So I suggest you either split this post off or move it to the first somehow.

I decided to "modify" this mod so it'll work in CPG 1.3 and my brother helped me fix the "_normal" bug

Just installed and works perfectly in CPG 132!

Thanks for this nice stuff!

Greetings

Hey,


I applied the hack to my page http://www.partynation.tv/ in the gallery and it works great.
BUT, unfortunetly, I can't make it work to use a transparent image...
Even if I save my png file as a transparent, it won't use it as a transparent watermark...

see the examples (I tried a few different files) in this album:
http://www.partynation.tv/coppermine/thumbnails.php?album=52
(First 4 pictures)

I use IrfanView to modify my pictures... The png file IS transparent.. I tested it with a basic html file and it works.
I attached the picture...


I really hope that someone of you can help me.
I'm not a great graphic guy...

(nor is my english really good, sorry)


Thx,
André

plz... can anyone help me?

If you are using Internet Explorer, you are out of luck.  IE doesn't display transparent PNG images correctly.  There's an IE PNG fix available on the web - http://koivi.com/ie-png-transparency/

[TheGamer1701]

well, I'm using mozilla firefox...

and actually IE DOES display the transparent png ...
but when I try to watermark my pictures with this png, I don't get an transparent logo...
everything that's meant to be transparent appears white...


any solution?

[Burpee]

Perhaps something is wrong with the way IrfanView processes transparency? I'll attach an image exported in PSP8, try it with that.

[kegobeer]

Something is up, because IE does not handle PNG-24 alpha transparency correctly.  Unless of course your images are PNG-8 with binary transparency, which IE does handle properly.

Go here and see how a PNG-24 image displays with and without the PHP fix.

This could be an issue with the type of PNG image you are trying to superimpose.  Try both PNG-8 and PNG-24 and see if either one of them displays correctly when applied as a watermark.

[Burpee]

Kegobeer, the images are applied on the server on upload. I don't think this is an issue with IE, I think it's an issue with GD2 not properly reading and applying the file.

[kegobeer]

Yeah, I'm sure you're correct, Burpee.  Perhaps an older version?

[Burpee]

I somewhat doubt it, GD2 doesn't change that much for as far as I know. However, the file that he attached was somewhat big in size for an image that small. If you look closely, you'll see that the image I attached is only half that size. Hopefully that will fix it for him.

hey, that's a great mod... however there are two things I didn't like
1. no transparency for the watermark
2. it's a final step... you can't undo the watermarking

so I made a mod of the mod. You can set transparency for the watermark and you can redo watermarking. Means you can totally get rid of it, or if you just want to have another watermark.. no problem at all. Other spot on the image... not a problem at all.

So if one of you guys is interested I'd put it up here... or is it wrong to put it in that thread???

[Tranz]

Please create a new thread in a board that you can post. A moderator will move accordingly.

[Stramm]

OK, it's in support-1.3-misc
hope you like it

[TheGamer1701]

Hey Burpee, I just fell in Love with you :-)


That image works perfectly, thank you very much.

Do you know where the error was?
thx

[Burpee]

No problem

I think the error was that IrfanView was not producing the right kind of PNG, messing up the alpha layer.
