Thank you Wayne for your rapid response to the bugs I posted yesterday!
Here is another macro-reproducible problem:
Rotate selection around image centre does not work for line selections.
It works correctly for all other selection types.
The below macro illustrates the issue.
The selection is placed in the corner, rotated around itself, then rotated around the image centre.
saveSettings;
run("Colors...", "foreground=black background=white selection=red");
run("Close All");
newImage("Rectangle", "8-bit white", 500, 500, 1);
makeRectangle(50, 100, 100, 10);
for (i = 0; i<360; i+= 30) {
run("Add Selection...");
run("Rotate...", " angle=30");
}
//ok
for (i = 0; i<360; i+= 30) {
run("Add Selection...");
run("Rotate...", "rotate angle=30");
}
//ok
newImage("Straight Line", "8-bit white", 500, 500, 1);
makeLine(50, 100, 150, 100);
for (i = 0; i<360; i+= 30) {
run("Add Selection...");
run("Rotate...", " angle=30");
}
//ok
for (i = 0; i<360; i+= 30) {
run("Add Selection...");
run("Rotate...", "rotate angle=30");
}
//failed, the line was rotated around itself instead of the image centre
run("Tile");
restoreSettings;
