"Imagick::clone method is deprecated and it's use should be avoided"

What should I use instead?

I want to replace the red channel with the green one in an image. I have a grayscale image mask (mask.png) that represents the region I want to change. How do I do it?

The code is for a script to reduce red eyes. I want to copy the "good" pupil from the green channel into the "bad" in the red.

Thanks that works. I also found out that fxImage('intensity') works as well. I used it the wrong way, the function return a new Imagick object with the changes.

Ok thanks for your answer. I actually tried fxImage and gammaImage first but I was uncertain of the parameters.
It's seems that you have to call gammaImage for each color:
$im->gammaImage($RED, Imagick::CHANNEL_RED);
$im->gammaImage($GREEN, Imagick::CHANNEL_GREEN);
$im->gammaImage($BLUE, Imagick ...

What's the equivalent to ImageMagick cmd "convert image.jpg -fx intensity -gamma $RED,$GREEN,$BLUE out.jpg"?

I have a dilemma reading colorspace from images. I you use the standard way identify -format "%[colorspace]%" you will sometimes get wrong result.

For example i you have a RGB image with a RGB profile sRGB you might sometime get colorspace: GRAY instead of RGB if the internal image consists of ...

I'm using ImageMagickObject in my C#.net application and I'm working with large images (40Mpixels).
Is there a limit how much memory can be allocated? I have plenty of ram (8GB) and I see temporary files gets created on the temp folder.
If I use the command line all the work gets into ram and no ...

I have a old linux system running Imagemagick 6.2.5 installed by using a prm package. For example convert has the following path /usr/bin/convert.
Now i want to upgrade to newest version by building from source but I want to keep the existing 6.2.5 installation as well (for the time I develop my ...

I think you need to use the full path to convert.

Use "whereis convert" to find out the full path.
For example /usr/local/bin/convert

You can try exiftool, http://www.sno.phy.queensu.ca/~phil/exiftool/

Exiftool can read and write photoshop meta info http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/Photoshop.html

I haven't tried it, but I think this should work
exiftool -g -Photoshop:XResolution=300 -Photoshop:YResolution ...

How do I get the version number from ImageMagick dll library?
I tried the below command (C#) but result is null.


ImageMagickObject.MagickImageClass magick = new ImageMagickObject.MagickImageClass();
object[] cmd = new object[] { "-version" };
object result = magick.Identify(ref cmd);

Ok thanks. I solved the problem using ImageMagick to convert the images to the right profile then used a PDF library to mount the images.
It seems that the PDF itself don't need an embedded profile.

When i use the below command the profile does not get embedded. If I change to output.tif there is no problem, the image gets converted to cmyk with right embedded profile.
Input.jpg have srgb icc profle.


convert input.jpg -profile CoatedFOGRA27.icc output.pdf


I'm using version 6.4.0, should ...

I have three grayscale images with a grayscale profile "Dot grain 20%". The formats are JPEG, TIFF AND PSD.
Shouldn't I get the same output image when converting the colorspace to RGB using a RGB profile?

convert image.jpg -intent relative -black-point-compensation -profile AdobeRGB1998.icc new ...

That does not solve my problem. I want to find a way to identify colorspace the same way that Photoshop does. It seems that the only difference between "-format %r" and "%[colorspace]" is the removal of prefix DirectClass or PseudoClass.

One interesting part is that I have tried an older version ...
