Details:
There was an original bug on this bug #48764 which now works in the current
version. But with a bigger image you still get a blank figure, image not
displayed and no error messages.
Octave 5.1.0 and image 2.10.0 package
It seems to be the x,y pixel size that is an issue it is not affected by mono
or rgb images.
In its simplest form
img_data = uint8(randn(6000, 8400)*255);
figure(); imshow(img_data);
Just displays a blank figure, although the pixel position display is showing
correctly or bigger in x or y (See fail image attached)
but
img_data = uint8(randn(6000, 8399)*255);
or
img_data = uint8(randn(8399, 6000)*255);
or smaller work fine.
(see pass image attached)
I don't think it makes a difference but it is on Windows 10 Pro 64bit i7 with
16GB memory latest download of everything (see splash screen attached)
Any insight very much appreciated
