Hi, Tim-<br>
Interesting idea!<br>
May I request the infrastructure to implement a slight embellishment
on the server-side?<br>
Many of us use online virtual-slides for testing medical students.<br>
It would be useful to have a mechanism to "shift" the locations in
both X and Y by moving the origin.<br>
If we randomly changed the origin on the Slide-Server with each
session, no student could cache that information for the next
examinee.<br>
Hope this makes sense.<br>

<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am working on a project at NIST (National
Institute of Standards and Technology) that deals with image
stitching. The images are acquired using a microscope stage
that takes overlapping images. One of the results of the
stitching yields an 80k x 80k pixels image. I am looking into
visualization software for these very large images and
stumbled across open slide.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I should not have a problem with outputting
the final image into a format that is supported by OpenSlide,
but the idea came to me that it might be exciting to provide a
position list to OpenSlide instead.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I was wondering if it would be possible
for me to add support into OpenSlide to visualize images that
are constructed using a CSV file that contain ‘path_to_file,
x_pixel_position, y_pixel_position’. Now the tricky part with
this technique is we would need to do blending on the
overlapping regions, so either linear, average, or overlay;
however, I think that it will not be expensive to do blending
on the fly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have peaked around the source code and
looked at various image format vendors, and wanted to get some
input on where to start with this project and what would be
the best way to hook it into OpenSlide.<o:p></o:p></p>
