Hi, list.
I'm brand new to Octave and am afraid that I don't have Matlab experience to
back me up. I have scoured the archives and googled around, but I haven't
found any clear winners as to why a brand new Octave install fails as follows:
octave:2> BW = imread('/home/cpurvis/Temp/20091002fronts.gif');
octave:3> BW2 = bwmorph(BW,'thin');
error: A(I): Index exceeds matrix dimension.
error: called from:
error: /usr/local/octave/share/octave/packages/image-1.0.10/applylut.m at
line 44, column 4
error: evaluating argument list element number 1
error: evaluating argument list element number 1
error: /usr/local/octave/share/octave/packages/image-1.0.10/bwmorph.m at line
551, column 5
octave:3>
This is a valid image, and I can even write it back out to a new .gif, and it
looks fine. The image stats are as follows:
Driver: GIF/Graphics Interchange Format (.gif)
Size is 2797, 2234
Coordinate System is `'
Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0, 2234.0)
Upper Right ( 2797.0, 0.0)
Lower Right ( 2797.0, 2234.0)
Center ( 1398.5, 1117.0)
Band 1 Block=2797x1 Type=Byte, ColorInterp=Palette
Metadata:
GIF_BACKGROUND=0
Color Table (RGB with 4 entries)
0: 255,255,255,255
1: 206,206,206,255
2: 0,0,0,255
3: 0,0,0,255
I can printf the size of the image after it's loaded, no problem. Converting
it to .jpg results in the same error.
Am I missing something very obvious that is a result of me being an Octave
newbie? If so, I'm dreadfully sorry, and I can continue to printf debug
messages as I work backwards.
My stats are as follows and my thanks is in advance!
