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 coders/Magick...

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 convert "{}" -t...

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. :oops:

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 directory `/usr/home/...

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 users. I don't know which othe...

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...

Ahh brilliant. I'm pretty sure this solves my problem at least. I'll try this when i get home from work.

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 colors by ...

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. :wink:
