Dear experts,

when importing text images I encounter a strange behaviour at least
with MacOS 9.1 and ImageJ 1.35h.

-----------------------------------------
For example:

Tab-delimited Text:

1.000000 0.000000
1.000000 0.000000
0.000000 1.000000
0.000000 1.000000


After import to ImageJ  as "TextImage":

List of "Profile" of first column:

0 1.000000000
1 1.000000000
2 0.000000000
3 0.000000000

List of "Profile" of second column:

0 0.001000000
1 0.001000000
2 0.999000013
3 0.999000013

-----------------------------------------

The first column is represented correctly, the second suffers from
severe lack of grey-value resolution. (32-bit float should be
accurate to about 7 digits.)

Any idea what I'm doing wrong or how to circumvent this problem?

Best
