Re: imread on Octave 3.2.0 for Windows

[Tatsuro MATSUOKA]

Hello

This topic is limited to the windows version of octave which can be dowloadded 
from octave-forge
repository so that the post should be done to address@hidden but not
address@hidden

I have tried the imread and encountered the same error.  This may be occurred 
by miss packaging of 
'magic.mgk'.  I have tried the several folders to place 'magic.mgk' but 
unfortunately I could not find
the place.  So this issue can be fixed only package maintainer Benjamin Lindar.

I will sent this mail as a carbon copy (cc.) to Benjamin.

Please wait until Benjamin will make a reply.

Otherwise you can use imread on octave-3.0.5 after installing image-1.0.8 
package which can be
downloaded from  

http://www.tatsuromatsuoka.com/octave/Eng/Win/

image-1.0.8_prebuild_oct_3.0.5_mgw.zip,, Prebuild image-1.0.8 package for 
Octave 3.0.5 for Windows
MinGW32 Installer. Please read the Readme.txt in the archive file to install.


You can use imread. Please note that imread of image-1.0.8 cannot read .bmp 
file. Please use .png ,
.jpg, etcs.

Regards

Tatsuro
