imagej/fiji xor selection with overlays
i’m using imagej/fiji.

$ imagej --headless --console -eval "print(getversion());" | tail -n 1

2.1.0/1.53g

given two region of interest, i know how to select the xor between the region of interest. in roi manager window, i will find the option xor in the more menu.

i’m searching of how can…
the imagej 1.53h20 daily build adds an overlay.xor(indexes) macro function that creates a new roi by xoring all the rois in the overlay with indexes in the array ‘indexes’. here is an example:

run("blobs (25k)");

makeoval(44, 31, 112, 106);

overlay.addselection;

makeoval(86, 74, 112, 106);

hi [@jason.danforth](/u/jason.danforth),

all objects in the document are stored in the objecttable (rhino.docobjects.tables.objecttable). if you just want to select them, you can loop through them and use objecttable.select() method

import rhino

for robj in rhino.rhinodoc.activedoc.objects:

if robj.isnormal:

… you could use kangaroo, but i don’t think it’s needed here.

instead i’d use inverse distance weighting to make a height field like this.

the key step here is making a mesh with vertices on the curves you want to keep sharp. one way of doing this is to split a s… hi [@jeffb](/u/jeffb),

i did some digging: imagej1 by default exports regular tiff files, even if those turn out to be larger than 4g. those files can magically still be read by imagej1, but since are not proper bigtiffs not by other tools. you can replicate this issue easily by trying to import one of your large files via file > import > image in imagej/fiji.

in order to open such files in knime, they have to be proper bigtiffs. you can export them via bio-formats, i.e. plugins > bio-formats > bio-formats exporter, by using the btf file extension for your files. i am not entirely sure if bf has a check built in that would make it a bigtiff even if the file extension were tif. this way, however, i was able to import a 6g btf file with the image reader.

if you want some more details, this issue has them:

stefan thanks everyone for your suggestions. i went with a modified version of [@weekend](/u/weekend)’s:

It appears that the resolution of the image is quite low so that it will suffer pixelization with any enlargement at all. Fidelity of a raster image is always dependent on how much effective resolution (what its resolution is at the size it is to be used) the image has. So a 72 ppi image will only have 36 ppi if it is enlarged to 200%. Use File>Export As and export at 300 ppi or higher and see if that makes a dif... yes for current region you can use a range 
  
something like this 
  

  

  

```
With Worksheets("sheet1")
.range("A1:e10").copy
```

  

  
the dot before "range" is important.
  

  
it will copy only from A1 to E10. modify to suit you this is my first time digging into the processing source code so i hope this helps. the problem you are facing is more of a java problem though than a processing one.

by extending pgraphics you would have to replace the renderer implementations to inherit from your subclass(tgraphics) and not pgrap… Are you talking about computer or camera card "root folder"?


Can you NOT check the Import option-

The computer "root" folder is not a good location to have photos.


When I select my Local Disk (C:) without any photo files, and have the option [Include Subfolders] unchecked, I see this-
