Title: Horizontal banding on watermarked images :)
Post by: ajt on April 11, 2013, 14:00

I didn't notice it before, because I used Imagick to resize images on my old server and there was no "banding". Now I moved my site to new host and  can use Symbiostock without modifications. It is visible only on white  surface.
My site may be sometimes down in next hours, so examples not mine:

I cannot see it, - there is the Symbiostock interlinked "SS" in my watermark, could it be that you are seeing?

Right, I see it on our image. Oh well, we'll need to go to ImageMagick anyway, to do the profile conversion.

Which one of you are on bluehost? Do me a favor? Can you go into your test area (last tab) and tell me if it says you have imagick installed? Just paste what you have. I put a special entry for it at the top.

One fine day we will have imagick running and a reprocessor right behind it. That will be a good day.

Great. I might have some help on that stuff. But can't say too early. Anyway, gonna try to ignore the forum questions while I get some stuff done on this theme. Maybe a release tonight or tomorrow with much good updates.

I cannot see any banding on laptop or tablet - am I going blind?

How on earth did you find the picture of the airer ?

Below is part of your image with modified levels.
And I investigated, that it is resizing issue. Resized image, before watermark adding, already has stripes.

I just did the same thing in Photoshop - which was the only way for me to identify the banding.

I couldn't see it with the bare eye looking at those pictures.

I just looked at one of my images and I do not have this banding issue.

I'm running my site on Hostgator and I have no clue which script is resizing the images. Should I check? Where do I do that?
