Post the results of this command

convert -version

It should list out all the delegate libraries you have installed. It should contain jpeg

If your IM version is too old to show the delegates, then run

convert -list configure

and post what it shows for the line starting with DELEGATES.

It would appear that you are missing the jpeg delegate library and perhaps many others depending upon how you did your install. If you installed from source rather than binary, then you need to install all the delegate libraries you need for jpg, png, tiff, ghostscript, etc

What platform are you on? linux, mac or windows?

I installed the latest version

Yes, i installed from source not from binaries. Do you any documentation on how i can install all these missing libraries.

I am using Linux.

DELEGATES ps zlib

Those are the only delegate you have. So you need at least, jpg, png, tiff

These are mine. I would recommend at least the ones in blue


DELEGATES bzlib mpeg fftw fontconfig freetype gslib jbig jng jp2 jpeg lcms lqr lzma openexr png ps tiff x xml zlib

I am not sure why gs or ghostscript does not show in the list any longer. It used to. So I would also suggest you install ghostscript so that you can convert pdf and ps files.

I am on a Mac and get all my delegates from MacPorts. I do not know if there is anything equivalent for Linux. But you can find (probably older delegates) at http://www.imagemagick.org/download/delegates/. But I would search Google for each one to get the most recent ones.

Once you have the delegates successfully installed, then you will need to reinstall IM so that it can find them. Watch the installs carefully to be sure they install. Often they need other delegates to be installed before they can install.

You may be able to get most of the needed delegates installed if you install from an IM binary. So see http://www.imagemagick.org/script/binary-releases.php

Thanks for the quick reply.

When i run convert -version command the results are,

So, now i installed all the libraries which i used by "Image Magick"

I am trying execute the below command

"convert in.jpg -modulate 100,0,100 duotone.ppm -clut out.jpg"

In the above command

"in.jpg" is my original image.
"out.jpg" is the output image name which we will get after running the command.
"duotone.ppm" is the ppm file which you asked me to create.

The error which i am getting is,

convert: Improper image header `duotone.ppm'.
convert: missing an image filename `678.jpg'.

I don't know why i am getting this error. can you please help me.

IM 6.3.7 is rather old (almost 500 versions old). It is not clear why it does not work.

convert: Improper image header `duotone.ppm'.
convert: missing an image filename `678.jpg'.

It would appear to be an issue with your ppm image and its proper headers. Did you form the PPM image correctly according to the instructions by snibgo? Be sure that there are correct line endings in the text file for the ppm. You should be able to open it in any text editor or use cat duotone.ppm Does it have the headers formed as he shows in his list.

I am not sure where it is getting 678.jpg. I do not see that in your command. But if the duotone.ppm image is malformed, then I suppose anything that follows that message is suspect until you fix the ppm image.


I copied the code for the duotone image and pasted into an empty text file and saved as duotone.ppm. I downloaded your image in.jpg. I ran this command successfully

convert in.jpg duotone.ppm -clut show:

It shows a very similar image to your input but with a slight bluish cast.

If I add -modulate, to desaturate to grayscale first, then it is colorize blue.

convert in.jpg -modulate 100,0,100 duotone.ppm -clut show:

Anthony's Examples says:

Before IM v6.4.0-10 the "-modulate" operator actually did use HSB color space rather than HSL colorspace. This was changed because of a bug report by a user about the above situation.

So your results will look different from the nominal results on more current IM versions.


This was in my IM 6.8.5.7 Q16 Mac OSX system.

I see only two possibilities.

1) your ppm file is corrupt (open your file in a text editor and copy all of it and paste into your reply here, so we can verify it is not corrupt)

2) your IM version is too old

From Anthony's Examples, it says

The "-clut" operator was added to IM v6.3.5-8. So your version should be OK, but it is close to when it was added and there may have been bugs that were subsequently fixed.

Yes i did. let me copy and paste the ppm file here. Let me know if am doing anything wrong.

Actually i am using "convert in.jpg -modulate 100,0,100 duotone.ppm -clut out.jpg"

Can you send me the duotone image which you got when you tested.

You are missing the headers that tell the file it is PPM. see viewtopic.php?f=1&t=23466#p98843

Add these three lines at the top of your file

If you still have trouble, let me know your email address and I can send you my duotone.ppm file

It fixed my problem thanks a lot.

But i have a one more question for you.

Below are two image url's one is the Original Duotone image (1st url) from our site and other one is which i converted by image magicx (2nd url)




If you observer both 1st image (1st image) looks little dull than 2nd one (Converted one 2nd image). What should i do to make converted one look same like original one.

right now i use command convert kar.jpg -modulate 100,0,100 duotone.ppm -clut sow.jpg to resize.

Do i need to change any modulate numbers?

How did you create the first one? It is likely the difference in the colorspace used by -modulate. As I mentioned, in your version the only colorspace you could use was HSB. But in more current versions of IM, it has been changed to HSL (actually you have the option to change it to HSL or HSB or possibly HCL).

I am not sure how to adjust it, but you could try changing the modulate hue value (the third number from 100) so that your image is a bit more blue. See http://www.imagemagick.org/Usage/color_ ... dulate_hue.

Also depending upon the input image coloration, you may be able to keep more of the input color by increasing the second modulate number (saturation up a bit from 0).

If you can provide your input image, perhaps we can test other techniques to try to match better using HSB colorspace.

You would have more flexibility if you upgrade your version of IM.

Here is the input image.

This is what I get by using in IM 6.8.5.7 Q16


convert khr.jpg -define modulate:colorspace=HSL -modulate 100,0,100 duotone.ppm -clut khr_hsl_duotone.jpg


which uses HSL rather than HSB colorspace in -modulate.




To be able to do that you need to be using IM v6.5.3-7 or higher for HSL using the define. So your cannot use the -define with your version. But if you are using IM 6.4.0-10 or higher HSL will be the default.

How can i upgrade to the latest one? Do i need uninstall the old one and need to install the new one with all the delegates?

Do we have different ppm headers for different tones? just like for previous Duotone you gave ppm header has
