What are your experiences with profile/color consistency when using Image Magick for resizing? I know @horst is probably the person with the most experience on this, (hope you can chime in here Horst) Problem: I noticed that In some cases Image Magic resized jpgs appear darker than the original, and after some digging it appears to involve various factors concering both the image preparation (Photoshop's save for web and even general profile handling before that) and the way the Image Magic resizing process is setup. - Images with an embedded (srgb) profile that were exported via Photoshop's "save for web" function with "convert to srgb" and "embed profile" ON, somehow result in muted colors and a darker image, (actually it looks very much like when you would assign an srgb profile to an image that was already converted to srgb before, not dramatic, but quite noticeable with e.g. reds and cyans.) - I tried multiple variations, with embedded and excluded srgb profile, "convert to srgb" on and off, but the result appears to be the same darker, muted image. Need to find time to do more structured testing though.. Possible causes: - The way the srgb profile is embedded in the jpg - The way the Imagick module detects/ignores profiles - Colorspace handling changes between imagick versions - One of the above plus these rather involved technical reccomendations (tldr: convert to linear RGB, resize, convert back) http://www.4p8.com/eric.brasseur/gamma.html#ImageMagick http://www.imagemagick.org/Usage/resize/#resize_colorspace Would be nice to get a discussion going here. I am out of my league with this, technical knowledge wise but I'll try to keep up Cheers guys, Phil
How are you using ImageMagick in conjunction with Processwire to watermark / affect a specified images directory automatically? For my gallery page, I would like to upload images as normal then have ImageMagick watermark the output of them on the website; all this done automatically and on the fly without me having to do anything except create the script Would love to hear your suggestions how this can be done or how you are using ImageMagick in general. Script examples are welcomed! Let's go!
