Rendering Problem?

[Edward Ando']

Dear All,
We have a Windows XP-64 machine with quad Xeons and 24Gb of ram. This
machine has ImageJ 1.43r (but the error occurs even with previous
versions), and has 22GB of RAM assigned to it. I have tried to reduce
the allocated memory to less than 1GB but the error stills occurs.

On this machine alone, when using 32 or 16 bit tiffs, they are rendered
in a fragmented way. If one double clicks in the window or resizes it,
this can sometimes cause the image to be drawn properly.

I attach an image where there should be a circle of grains in the
middle.

Any ideas?

Thanks,
Edward

Edward,

I am pretty new to ImageJ so I may not be correct here. But I have seen this
behavior when trying to display tiled tiffs (as opposed to stripped tiffs).
However if this is the case I do not think a window resize would fix it.
Again I'm not sure. Can you find a program to determine if the data is
stored as tiles?

I have a problem that looks like this on my computer except that
images are broken up and displayed in vertical strips.  Each strip is
256 pixels wide.  If I shrink the view so that the entire image fits
into a box less than 256 X 256, then the whole image as a thumbnail
looks ok.  Also, A screen snap of the image looks wrong but saving the
image directly within ImageJ saves the correct data.

Here are some of the computer specs.
AMD Athlon 64 X2 Dual Core 4800+
2.00 GB
32-bit Windows Vista Home Premium
NVIDIA GeForce 6150SE nForce 430

Thanks for your replies,
The tiff are saved line by line (we are also seeing this behaviour with
raw files). I also get the same "rendering only" problem whereby if one
saves the images, they are fine, it is just their display that doesn't
work.

Any further ideas about what I could do?
Thanks,
Edward

Hi Edward,

just a few fairly trivial ideas, maybe you have tried all this already:
- are there any updates to the graphics card drivers?
- any updates to the Java version you are using?
- I don't know for Windows 64, but on XP many graphics cards have  
advanced settings where one can reduce the graphics acceleration  
settings and disable 'write combining' in case of problems with the  
display.
