atlc
generates error messages. Most are pretty obvious in meaning, but you might get an error like this, which is not quite so obvious:
% atlc bad-file.bmp Error: The colour r=0x9 g=0xff b=0x9 exists in the image, butYou may get this error if you simply try to use a different colour for another dielectric but forgot to define it. This can also happen if your graphics programme interpolates the colours in your image. For example, assume you intend drawing an elliptical conductor inside a rectangular cross section. The square grid will never fit an ellipse precisely, so the shape will look like this, which is shown on a very low-resolution image to make it more obvious
the programme does not know how to interpret this colour.
This is not a conductor (pure red, green or blue), nor is it
one of the 10 dielectrics that are predefined in Erdata.h,
nor is a corresponding dielectric constant defined on the command line
atlc
. At any sensible size of bitmap, the smoothing will not be obvious, so you may find atlc
exits, when the image looks fine.atlc
is not sure how to interpret.
