This worked for me in the end - I just explicitly applied gamma to the image itself to lighten the resulting greyscale image BUT I still needed to strip out the gAMA setting int he header:-

Unfortunately I am still getting a darker grayscale (greyscale) image when viewing the output in IE (IE 11 in my case). Only the image created in the command-line version generated the desired grayscale I require - I think the gamma metadata setting was a bit of a red herring - i.e. in my original ...

Hey thanks for that - it worked, the gamma (or gAMMA as its seem in TweakPNG) meta has been stripped.

Glad to oblige - I have uploaded a grey image to a temp storage here (28 days expire) : http://www.tiikoni.com/tis/view/?id=05800fd If you view the image in IE and other browsers you will see it is darker in IE - I need to strip out the Gamma metadata to normalize the display consistently with IE ...

It took me several days to figure out the installation on Imagick on our Windows Server 2008 with PHP 5.3, no kidding. On a Linux server, it literally took a few minutes with "apt-get install..." etc. The big lesson I learned is that it's all about VERSIONS for Windows:- * Version of Imagick dll ...

Searching this forum for answers I got this: http://www.imagemagick.org/discourse-server/viewtopic.php?f=7&t=10176&p=32368&hilit=meta#p32368 ...I'm guessing this is a similar issue of wanting to change met-data (?) so I will probably use the same trick of invoking the command line ImageMagick within ...

Hi, I did a lot of research to find out how to strip out the metadata in an output PNG image - this was due to inconsistent display across browsers (Gamma correction in IE!). This is the command I got to work at the command line using ImageMagick:- convert input.png -define png:include-chunk=none ...

No suggestions or advice? I was testing various scenarios :- Scenario 1 Non-Memcached image with compositeImage() i.e. current implementation --> works $img1 = new Imagick('pink.png'); $img1->compositeImage( new Imagick('http://'.$my_dynamic_image.'.png'), imagick::COMPOSITE_COPYOPACITY, 0, 0 ...

Hi, I have an "on-the-fly" image process which performs alpha compositing of an alpha-transparent image to a colour-filled image. The colour-filled image is static whereas the alpha-transparent images are dynamically called - and there are a lot of them. I use the $img->compositeImage() and ...

Replying to my own thread with my experience so far (as noone replied). Doing many a search for the various compiler errors I got trying to include Magick++ into my working ISAPI project in VC++ 2008 Express Edition, I saw many a post by Magick admin to load the Button example and use that as ...

Hi, Has anyone tried using ImageMagick in an ISAPI extension DLL? I would like to develop some web server application which, when it gets 2 image requests, intercepts the call and does some graphics processing e.g. apply opacity and merge the 2 images to return 1 image. I am using Visual C++ 2008 ...
