Magick ++无法读取原始Nef图像

Question

I am trying to read a raw image using magick++. According to this list the nikon's NEF format should be supported by image magick. http://www.imagemagick.org/script/formats.php

Here is my code...

int main(int argc, char** argv)
{
    Magick::InitializeMagick(argv[0]);
    Magick::Image im;
    im.read("/home/chase/Desktop/DSC_0985.NEF");

    im.display();
    return 0;
}

I get the following error message...

terminate called after throwing an instance of 'Magick::ErrorBlob'
  what():  Stacking: unable to open image `/tmp/magick-25923_ETdn5fNSJR5.ppm': No such file or directory @ error/blob.c/OpenBlob/2709

I installed magick++ using sudo apt-get install libmagick++-dev . I am using ubuntu 15.04

I just tried this as well. Same error. NEF should be supported.

Magick::CoderInfo c("NEF");
if(c.isReadable())
{
    Magick::Image im;
    im.read("/home/chase/Desktop/DSC_0985.NEF");

    im.display();
}

Answer 1

I don't use Ubuntu, but on OS X at least, ImageMagick uses ufraw and ufraw-batch for NEF , DNG and CR[2W] raw files, so I would suggest you try installing those, presumably with something like:

apt-get install ufraw
apt-get install ufraw-batch

Answer 2

ImageMagick not read directly RAW they use dcraw for convert to .ppm and them open it.

Try install dcraw .
