Wired Problem when use AlphaData
显示 更早的评论
I am using R2010 Matlab (7.10.0). I meet a very strange problem when I use set(h, 'AlphaData', 0.3) to generate the transparent image, the output image is transparent but with interleaved white strips (horizontally). Say the following is my code:
figure, h = imshow(image) % correct output image
set(h, 'AlphaData', 0.3) % problem occurs
I tested many images, it seems that RGB images don't have the problem; all the gray images have this issue no matter they are double or unit8.
Does anyone have any clue what's happening??
Thank you in advance.

Which OS are you using? And which java version ?
I suggest you try
opengl software
drawnow
and see if that helps.

I do not know what the real cause of the problem is, just the solution.
R2010b (I think it was) had graphics oddities on Windows;
R2011a (I think it was) had graphics oddities on Linux;
R2011a and R2011b had graphics oddities on OS-X Lion, and (different) graphics oddities on OS-X Leopard and Snow Leopard in conjunction with a Java security fix that was implemented at the same time that OS-X Lion was released.
Versions above are from memory, as I do not have any of those myself.
