Tranparent background watermarks, can it be done?

[GrBear]

I made a PNG file, that I'd like to use as a watermark on all uploaded images. In an effort to make it less obtrusive, I made it with a background transparancy of 90% (only 10% will be visible).

For some reason GD makes the transparent background black instead. Will one of the other image manipulators work better for me?

Thanks!

GB.

If you use ImageMagick then that should allow for the 90% transparency.

Cool, thanks Brian. I'll give that a shot and report back.

Hehe.. oh the saga continues..

So I got the latest imagemagick installed, but it won't put the watermark on the image I upload. I change the pulldown setting in config to GD, and the watermark appears on the next image I upload.

Any ideas?

The uploaded picture is a jpeg, and the watermark is a png.

For what it's worth, GD will do transparent watermarks.. the watermark file needs to be in a PNG32 format. Never did get ImageMagick to work though.. there was no way of determining if the 'composite' command was working or not.

What did you set the path to for IM?

I could never get ImageMagick to work with VBA Gallery either. It worked perfectly with Coppermine, 4images, Photopost, every script except VBA Gallery.

I even asked my host to install the latest version... nothing!

I compiled it to install into: /home/imagemagick

The binaries are located in: /home/imagemagick/bin

Thusly, I've set the path to IM as: /home/imagemagick/bin/

I had the path set before without the trailing slash, and I would just get errors. After reading a few more posts, I found out that I needed to add the slash which caused the errors to go away.

It does the resizing properly, so I know 'convert' is working fine, and after poking through the gallery code, I see gallery is using 'composite' (for watermarking) which is in the same directory as 'convert' yet it's not doing what it's supposed to.

Strangeness..

Strange... If you'd like to submit a support ticket I'll be glad to take a look.
