post your full command line. I don't see enough to know what you are doing. Also post a link to one of your files that do not work and perhaps someone at IM can see if there is a problem with those files.

the convert syntax usually has the input image before any of the options. have you tried

convert inputimage ... options .... outputimage


Unfortunately, I do not know anything about .ai files. You could post a link to one and perhaps we can test with it.

There have been a lot of posts related to this topic. Use the search feature and include the search words, RGB CMYK. To do it properly, you probably need to use a profile. But I am not an expert on this topic. Also see: http://www.imagemagick.org/Usage/channels/ Also certain image formats do not sup...

Hello, Many of my scripts are breaking when I try to extract the min, max, mean and standard deviation from the -verbose info: for a grayscale image. (I found this with the current IM 6.4.0-3 running Q16-hdri). This appears to be due to a change in capitalization of these words in the -verbose info:...

Timing will depend on many factors - your processor, the length of the text and the effect. As I mentioned, some of these effects require -fx until Anthony can code them directly in IM. On my Mac 1.42 GHz processor some three-word text effects take only 1 second, but some that use -fx take 20 second...

I do not know why it should not work with either png or jpg unless you need to use transparency and then you need to use either gif or png. However, colors will not be preserved as well using jpg because it is a lossy compression format. With regard to speed, unfortunately there is nothing that can ...

I think you should be able to put all your command line arguments in a file and write a script that would read the file and put all the text into a string variable and then have the IM command reference the string variable,

convert $commandlineargs

or

convert infile $comandlineparameters outfile

When I was installing the binaries from IM on my Mac OSX Tiger, I had to modify my .profile file in my home directory. You can find it using the terminal by going to your home directory and typing ls -al That should make a list that show .profile To see it type cat .profile I then modified it (using...

Each line computes a separate variable that is needed later by the script. d is the distortion amount provided by the user from input. The others are computed using IM option -format and some use -fx to do calculations. Look at -format, -fx and -fx escapes See http://www.imagemagick.org/script/escap...

I have simplified my script for doing barrel and pincushion distortion only in the vertical dimension for you. It uses no Unix, only IM commands to get and compute parameters. Here is an example: input text image: http://www.fmwconcepts.com/misc_tests/TextWarp/fredtext.jpg barrel distorted: http://w...

Thanks. I have already cleaned it up by hand. But I will keep this note for the next round. I appreciate the reply.

Cartesian to polar is the type of transformation. It uses equations such as r=sqrt(x^2 + y^2) angle=atan2(y,x) and x=r*cos(angle) y=r*sin(angle) With regard to -implode, I don't know of any way to make it do it to just one dimension without doing a custom distortion mapping or writing equations such...

He uses a cartesian to polar transformation to do the "arc" distort. By the way, to do something like the barrel and pincushion distortion with IM commands see the implode function. I think that may do what you want. Implode with positive value is like pincushion and implode with negative ...

When Anthony gets back from his trip in early April, he plans to implement something like my pincushion script directly in IM. So that would speed it up tremendously. Unfortunately, -fx is very slow for this complex a function. The bubblewarp script may work also for you, but is slow also. Some of t...
