FW: bug in Histogram / calibration

[Prodanov Dimiter]

Dear all,
I discovered a bug in the image histogram calibration. The image is 16 bit.
I calibrate with density=pixel - 32768 and here is the result I get:

n  No negative value bins are displayed

n  The scale in the graph does not correspond to the numerical values
Best regards,

Dimiter

This problem is caused by a bug in the Analyze>Calibrate command that has been fixed in the 1.43o daily build.
