ImageMagick and OpenEXR

[macot392]

Hi,

I bought a Qnap NAS which I install the optware plugin to support ipkg packgage on linux. This way, I've installed imageMagick which work normally through PHP, but I would like to know how to add openEXR support to it?

ImageMagick seems to support OpenEXR image, but it relies on "external delegate" to decode this kind of image. This probably means that I need to install the OpenEXR library and than "link" it with ImageMagick.

As I'm a beginner, could someone give me some precise step on how to achieve it.

Thanks in advance for your help.

The only way I know (on unix) is to download and install the OpenEXR delegate library, then recompile IM from source. If that works,

convert -list configure

should list openexr in the line starting with DELEGATES.

Note however, that IM only supports "half" mode (16 bit) openexr format.

There may be a way to install openexr and then link to the IM binary, but I do not know how to do that.
