Description

When adding a Calibration Bar via Analyze->Tools and setting a low zoom level of, e.g., 0.1 (which is often necessary when adding calib. bars to very zoom in content), the calibration bar is not drawn correctly any more. As shown in the image below, the colored stripes protrude through the black border:

Please provide a small macro I can use to reproduces this bug.

Sethur commented 7 months ago

@rasband Sorry for the slow response. Here is a macro for reproduction:

run("CT (16-bit DICOM)");
run("Fire");
run("In [+]");
run("In [+]");
run("In [+]");
run("In [+]");
run("In [+]");
run("In [+]");
makeRectangle(488, 212, 26, 34);
run("Calibration Bar...", "location=[At Selection] fill=None label=White number=5 decimal=0 font=12 zoom=0.3 overlay");

This will create a misrendered calibration bar in the top right of the zoomed part of the image. The misrendering happens when low zoom factors are set in the calibration bar tool (such as the 0.3 here), which is needed for high zoom levels.
