Ok. I'll close the report. If there is reason to conclude the problem may be with Octave, we can reopen it.

Works for me on Debian wheezy, octave dev branch, with integrated Intel graphics:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

Both gnuplot and fltk draw for me using your 501x200 example.

it works on another Debian PC, which is attached an NVIDIA GPU. it didn't works on an onboard Intel GPU PC. it may be an OpenGL driver problem, not but an octave.

Hi Doug,
Hmm....Are you using fltk backend? In my Debian(squeeze), it works with gnuplot backend, but not works with fltk backend.

I just happend to find a bug about drawing image.
It occurred under using both "imagesc(), image()" and "axis image" routines.
Apparently, the matrix size of 501xN is not drawn.

%% CODE EXAMPLE %%

N=200; % any value
imagesc(rand(499,N));axis image; % OK
imagesc(rand(500,N));axis image; % OK
imagesc(rand(501,N));axis image; % BUG(NOT DRAWN)
imagesc(rand(502,N));axis image; % OK
imagesc(rand(503,N));axis image; % OK

imagesc(rand(499,N));axis equal; % OK
imagesc(rand(500,N));axis equal; % OK
imagesc(rand(501,N));axis equal; % OK
imagesc(rand(502,N));axis equal; % OK
imagesc(rand(503,N));axis equal; % OK

imagesc(rand(499,N)); % OK
imagesc(rand(500,N)); % OK
imagesc(rand(501,N)); % OK
imagesc(rand(502,N)); % OK
imagesc(rand(503,N)); % OK
