[Pkg-octave-devel] Bug#438465: octave2.9-forge: image/edge.m fails with 'wrong type argument'

[Andreas Romeyke]

Subject: octave2.9-forge: image/edge.m fails with 'wrong type argument'
Package: octave2.9-forge
Version: 2006.07.09+dfsg1-8
Severity: normal

*** Please type your report below this line ***
Hi,

I load an image with following lines:
	image=imread("test.png");
	imshow(image);
	edgeimage=edge(image,'sobel');

The last line triggers an error:
	error: octave_base_value::matrix_value(): wrong type argument
`uint8 matrix' error: evaluating binary operator `.^' near line 77,
column 39 error: evaluating binary operator `+' near line 77, column 43
	error: evaluating assignment expression near line 77, column 7
	error: evaluating if command near line 65, column 1
	error: called from `edge' in file
	`/usr/share/octave/site/api-v22/m/octave2.9-forge/image/edge.m'
	error: evaluating assignment expression near line 8, column 10

The same code does work under Debian Sarge`s Version of Octave and
Octave forge.
