Hi Curtis,<br><br>Thanks for the information.<br>We are currently testing the following method to open image tile by tile:<br> byte[] openBytes(int no, byte[] buf, int x, int y, int w, int h)<br><br>but it appears that all reader do not support it very well, we tested both on JPEG and NDPI reader and obtained errors in both case. Is there any way to know how much this method is supported ?<br><br>Glad to hear about the IJ2 work on smart image disk caching, i am impatient to see that in action :)<br><br>Cheers,<br><br>- Stephane<br><br><br>Le lundi 29 avril 2013 17:40:21 UTC+2, Curtis Rueden a écrit :<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;"><div dir="ltr">Hi Stephane & everyone,<div><br></div><div><div>> We are also developing a plugin which may be used to split very large</div><div>> images in tiles but again we are very dependant to what the</div>

This week, the ImageJ2 team will be working on the underpinnings in ImgLib2 for a SCIFIO-driven CellImg with intelligent disk caching.

We are also developing a plugin which may be used to split very large images in tiles but again we are very dependant to what the Bio-Formats library is able to do so it could be limited in some way. Did you try to re open your image with the last version of Bio-Format ? you should have received an automatic update last friday.<br>

Hi again, thank You for Your reply. Is there a quick way to reduce
the X/Y in images, or has that to be done <u>before</u> importing
them to ICY or maybe even when the slides are beeing scanned?<br>

4 or 5 GB is really huge image, if the X/Y dimension is too large
(> 32000x32000) then you may experience problems to open them.<br>

<div>hi, thanks for Your reply. we will be able to scan to
.tiff soon, that should resolve the issue. FYI the mirax
files are aprox 4.5-5 GB, dont have the x/y</div>

<div>Hello,<br>
<br>
Sorry for the delay !<br>
Actually mirax format is not yet supported by Bio-Formats
(the library we use to open image files) :<br>

<br>
But at some point they will add support for it.<br>
From the error message we counld think your image is too
big to be laoded, do you know the size (X / Y dimension)
of your image ?<br>
