Re: IM Install Error
Uhm... I'm a bit of a noob when it comes to compile issues. I'm on FreeBSD 9.0 (32-bit Intel) and I'm only getting to this point, when doing a "make". Would the above trick work here? (And what exactly did you do? I'm not sure I get it.) CC coders/MagickCore_libMagickCore_la-jbig.lo CC cod...

Re: Blurring A or B channel in LAB color space
Great works, guys. I'm gonna take a shot at playing around with all this as soon as I get the time. PS: When embedding color profiles into png and jpeg images, each browser has its own surprising way to interpret it. My best work-around for this has been to convert images to sRGB and then completely...

Re: Hey, that works for me
I just ran into the same problem, but with "ImageMagick 6.7.5-10 2012-05-23 Q16" adding -type truecolormatte PNG32:output worked perfectly. Thank you! :o Edit: It worked when scaling to 32x32 pixels, but not when scaling to 16x16 pixels. How odd. Works: find . -iname '*.png' -execdir conve...

Re: Blurring A or B channel in LAB color space
I used Photoshop indeed. I didn't display them as grayscale in order to show what colors they actually are, but yes, they are represented as grayscale inside Photoshop. The exact steps in Photoshop are: 1) Convert the original to LAB color 2) Select the A and B channels (the color portion of the ima...

Re: Blurring A or B channel in LAB color space
Well basically the L channel of LAB is perceptual brightness, i.e. a grayscale image. The A channel contains values ranging from green to magenta, with values around 50% being neutral gray. The B channel ranges from a cold yellow to sky blue. Because all values are going from a minimum value to a ma...

Re: Blurring A or B channel in LAB color space
Thanks for the update on the blur. Here's the original image, so that people can give it a try: http://www.robotplanet.dk/f/imagick/noisy.jpg When blurring the A and B channels you should get the following result. You can see that the tiny color variations in the noise have become less prominent, an...

Blurring A or B channel in LAB color space
Hello, I was just trying to remove some nasty color noise by converting my image into LAB color space, and then blurring the A and B channels, leaving the L channel intact. This is giving me some surprising results. What am I doing wrong? Here are the command lines I used and the resulting images: T...

Update
The version that kept appearing when installing ImageMagick was even older than 6.6.1.10 (which actually does have the FFT feature.)
I'm up an running. Please disregard above post.

Building on FreeBSD 7.2
Can anyone give me a few hints on how to make ImageMagick 6.6.3-0 compile on FreeBSD? I guess I have to use "gmake" rather than "make", but I get this error: magick/.libs/libMagickCore.so: undefined reference to `carg' gmake[1]: *** [utilities/animate] Error 1 gmake[1]: Leaving d...

make or gmake (FreeBSD)
The install guide on the web page says "Install from Unix source" and mentions these commands: $magick> cd ImageMagick-6.6.3 $magick> ./configure $magick> make Under FreeBSD I'm pretty sure you have to use "gmake" rather than "make". This might confuse less experienced ...

Re: Subdued brown vs. yellow
Just a thought on the sideline here: The subdued brown color you mention is probably just yellow in a very dark version, because dark yellow is basically some sort of brown. I've found out that when comparing colors (like for example searching through a database with images), comparing colors in the...

Re: Common colors?
convert logo.jpg -colors 16 -depth 8 -format "%c" histogram:info: | head -n 3 colors.txt This one keeps the first three colors out of 16. ImageMagick sorts the colors by brightness, so you're throwing away the brighter colors, and not the less common ones. I wish there were a way to sort ...

Re: Abstract oil paintings
Hah! Great suggestions. This sort of thing can be tweaked endlessly. I've been asked for a "desktop sized version" a few times too. I might make such a thing, but it would be an "image of the day" sort of thing, in order to not stress the server too much.
