Bug ID: 1092
Summary: Incorrect units for y and z; subsequent Bio-Formats
bug
Product: Fiji
Version: unspecified
Hardware: PC
OS: Windows
Status: NEW
Severity: normal
Priority: P4
Component: Plugins

This might actually be _two_ bugs.
1) Running 'Image > Properties...' or 'Analyze > Set Scale...' to change the
units and scale will change only the units for x, *not* the units for y and z
directions.
The same problem apparently occurs when saving a virtual stack (with micron
calibration) to a tiff stack: the resulting file will have microns in x and
pixels in y and z.
2) As a consequence, when you save such a "mis-scaled" image and read it with
Bio-Formats Importer, the stack trace pasted below is thrown. Unfortunately,
this breaks any use of the Grid/Collection Stitching plugin because it
exclusively uses Bio-Formats to open even "Standard ImageJ" tiff files.
I suggest that the Bio-Formats Importer should be a bit more forgiving and
issue a warning only, instead of throwing an exception here.
This macro code illustrates both issues:
// ******************************************************
tmp = getDirectory("temp");
file_name = "calibration_bug.tif"
newImage("Calibration_test", "8-bit black", 100, 100, 20);
run("Properties...", "channels=1 slices=20 frames=1 unit=um pixel_width=0.8
pixel_height=0.8 voxel_depth=0.8");
Stack.getUnits(x, y, z, t, val);
print("Units: x=" + x + " y=" + y + " z=" + z + " time=" + t + " value=" +
val);
saveAs("Tiff", tmp + file_name);
run("Bio-Formats Importer", "open=" + tmp + file_name +" color_mode=Default
view=Hyperstack stack_order=XYCZT");
// ******************************************************
Here's the stack trace:
