[SOLVED] Question about image merges

[EchoFool]

Just a quick question about image merges, can it also save images to the server after watermark, or is it only for having an image on top of another image when outputting the image to the browser... or can it do both ? And if so, which is most likely the better choice for least amount of processing power (i like to keep my server efficient after all hehe)

 

Hope you can shed some light on this for me.

Use imagemagick for image manipulation. Far better than any method using the GD library.

Then again, not every host offers it and its often slower.

Not to mention that if you're using the Imagick/ImagickDraw classes the documentation is very very poor.

 

Back to the OP, (hope I understood the question right)

Yes you can save a modified/watermarked image on the server as well as outputting it 'on the fly'.

 

And as you already indicated, it's far more efficient to do the first.

Ok so its far more efficient to create a new image with the watermark and just save it rather than output the merged image.. is this because the amount of times a user views the image means it has to merge it every time ? Which is what would make it less efficient ?

[Axeia]

Yes.

 

It's doing the computation one time (when you process it) vs on every page request. Which tends to cause problems once someone starts spamming f5 on the page or when you just got a lot of visitors.
