Blur

[jupiter]

I've tried several different methods and parameters now.

but the code:

Image image( "100x100", "white" );
image.read("test.jpg");
image.blur(6.0, 1.5);
image.write( "test123.jpg" );

doesn't change the image at all.

what am i doing wrong?

thanks in advance

I don't know much about the Magick++ API, so your problem may be with how you are coding it.

However, try leaving the radius=0 and just change the sigma. IM will compute the appropriate radius. note the radius that it computes will be about 3x sigma

Works for us. We're using ImageMagick 6.7.3-6 and this code:

Code: Select all

// g++ `Magick++-config --cxxflags --cppflags` -O2 -Wall -o magick magick.cpp `Magick++-config --ldflags --libs`
#include <Magick++.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
using namespace std;
using namespace Magick;

int main(int argc, char **argv)
{
  Image image( "100x100", "white" );
  image.read("test.jpg");
  image.blur(6.0, 1.5);
  image.write( "test123.jpg" );
}

well i don't get it to work.

is the blur effect then directly written into the image? so writing the image should write the blurred image to disc right?

[magick]

Correct. We get a blurred image.

[jupiter]

actually i don't. it looks the same as the original image. but binary data is different

[jupiter]

could you provide me you prebuilt lib? just in case i did something wrong with compiling it myself. i still don't get a blurred image, and shadow doesn't work neither.
