Showing 2 images side by side

[Richard]

I want to create a plugin that lets me load two images, side by side, and lets me simultaneously zoom in on both of them. My Java skills are rusty and I'm not sure where to start. Can any one give me some advice and point me in the right direction?

at least for the tricky part there is already such functionality: the
"Sync Windows" plugin. So unless you need something very special, there
is no need to re-implement this. On the other side, you could have a
look at the code of this plugin, if you still plan to do something new.

Cheers
Niko

Hi Niko,

Thank you for your quick reply! I have looked at the sync windows plugin. When I zoom the upper left corner of each window remains fixed but the size of the image changes. I need the two windows to remain in the same orientation on the screen, and remain the same size too. The code seems rather complex for my level of skill. Is there a simpler approach?

Thanks for your help,
Richard

that's the default behaviour of ImageJ - you could trick it into keeping
the size by moving the image window to the bottom of the screen, so
ImageJ doesn't have the space to increase the window size. It will zoom
in then, and show the navigation overlay, instead of enlarging the window.

Otherwise, I am not aware of any other way to adjust this behaviour
(except for touching the code). Maybe anyone else?

Cheers
Niko

Hi Niko,

If you don't mind trying things sideways, have a look at Icy's synchronised window system (http://icy.bioimageanalysis.org). You can multiple windows using the padlock symbol, which lets you choose between full X,Y,Z,T sync, or just X,Y, or just Z,T. The zooming always focuses on the mouse cursor position (which also adds a crosshair in all viewers for pixel value checking). Since Icy has ImageJ built-in, you can still use your favourite plug-ins and bridging images to Icy when in need of synchronisation. Worth a try…
