View Full Version : GD To Process Images, ImageMagick to Watermark

Well you can use ImageMagick to process the images and GD to do on the fly watermarks if you do not want the images to have a watermark permantly done
One drawback is to make sure you do not allow gif uploads.
If you want permenant watermarks your stuck with using one processor for both.
The reason you can get away with using ImageMagick to process images and GD to do on the fly watermarks is that the watermark.php is an external call that handles the overlay and reqwuires GD. But you can not have it the way around.

well why not use one processor as you can see you can only have things set the way I stated above.
The way you go depends on the type of watermark you want.
What is your preferred processor?

I would look at your compiled processor and do some thinking
I use ImageMagick which I compiled myself
I upload a 2048x1560 image which is 700KB
When I upload that I get three files
a 2.89kb thumb
a 44.7kb medium
a 107.3kb large file

That is why I posted the above post. That is an uncompressed 700kb image from my Nikon 995 Coolpix and ImageMagick successfully compressed it and created much much smaller images.
If you want GD to do on the fly watermarks you can do as I stated and use IM to process the images and allow GD to do the overlay but your original post had things the other way around.

Steve that is because you are using permanent watermarks which is set in your options settings.

I am trying to implement the configuration suggested above: GD does the on-the-fly watermarks and IM does the rest. In options I disabled watermarks. In config I set IM as the thumbnail generator and set "yes" to on-the-fly watermarks.
Then I tried to rotate an image and got this message.
Error rotating image!!
