Dick,
Your last changes in eeschema are very promising.
I noticed you have problems with the "convert" option in component
editor dialog.
This this relative to the "De Morgan" double representation of gates.
Eeschema handles more than one shape for a given component.
(in fact as many shapes as you want)
But usually 2 shapes are enough (i.e. the De Morgan representation of
AND, OR gates like a 74ls00).
I do not know if "De Morgan" has a meaning in USA.
This means only for an AND gate (with active high inputs/outputs) like
a 74ls08 the hability to used it as a NOR gate with active low
inputs/outputs
So an option like convert/normal selection for these gates is usually
enough.
The convert choice select the second shape entered for this component.
Note i used also this feature for some components that have 2 modes of
operation (with very different features in each mode),
to show them with the best appearance according to the selected mode in
my schematic.
The function int LookForConvertPart( EDA_LibComponentStruct* LibEntry )
(in getpart.cpp) returns 0 or 1 for components with a single representation
(or the number of shapes for the same component. Currently <= 2 )
By the way, have you tested the last version of zones handling , with
the last enhancements ?
