still problem of loading 32 bit tiff image using imread after reconfiguring GraphicsMagick

[Yang, Fei]

Hello all,

 

I am a new user of Octave, and I use the version running in Centos linux.

 

Currently when I tried to load one 32 bit floating-point image into Octave using command ‘imread’, I found it had been automatically converted to 8 bit. Also I got the error notice as: warning: ‘your version of GraphicsMagick limits images to 8 bits per pixel’.

 

After searching the internet, I downloaded GraphicsMagick and configure to 32 bit, following the link below (But I adjusted his methods and download what I want for Centos system.

http://marcelojoeng.blogspot.ch/2012/11/compile-octave-using-1632-bits-colour.html

 

Then I follow the instruction on that webpage and re-download Octave and recompile it.

 

However, the situation did not change, still all the images that I used ‘imread’ to load were converted to 8 bit. And I tried many times.

 

So could any of you please give me some suggestions to solve this problem?

 

Looking forwards to hearing from you! Thank you very much!
