Import error: invalid rotation angle

pdumon

I'm getting an error 'Invalid rotation angle (450 is less than -360 or larger than 360) (...)' on a file. I'm not sure the Gdsii stream spec limits the ANGLE to -360 to 360? (not in the spec I have). Anyway, maybe (dis)allowing this as a GDSII reader option or so?

Hallo,

this is actually just a warning. It indicates that there may be something weired going on, but KLayout will reduce the angle to a range between 0 and 360 degree. I think it is worth mentioning strange angle values because that may indicate some other issue (i.e. a corrupt file). Still the file can be perfectly valid.

Best regards,

I wanted to add that for text rotations, the angle is limited to multiples of 90 degree. The GDS spec allows any angle.

Best regards,

Well, KLayout gives this and when clicking the OK button, just exits. So it's not just a warning apparently.

Hallo,

you're right, it's a warning for texts but an error for instances.

I'll change it to a warning in the next release.

If you're able to build KLayout, you can replace the error around line 894 of dbGDS2ReaderBase.cc by a warning:

 warn (tl::sprintf (tl::translate ("Invalid rotation angle (%g is less than -360 or larger than 360)").c_str (), angle_deg));

instead of

 error (..., angle_deg));

Best regards,

Matthias
