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 [email protected] but not [email protected].
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.
