Hello, Maximiliano, > ... oregano uses cairo now ....
thanks for that inside information you give! > So, removing the option from the export window might be the best option. Technically, yes, that'd fix this bug. But only in a formal manner. Individual circuit elements come out red, connecting wires partially red, partially blue, connection points black, writing in green. (I enclose an example.) These colors are useful for me while working in Oregano. But they are no longer useful in the exported end result circuit diagram. From an end result perspective, these colors do not make sense; not for my purpose, anyway. Again: > So, removing the option from the export window might be the best option. Ok - but I'd be asking for a black and white option, as a "wishlist" feature request. (If you develop folks think two steps are a good way to handle this, we can do it that way.) Finally, for the record: As my workaround, I presently use something like pngtopnm < XYZ-color.png | ppmtopgm | pgmnorm -wvalue 255 -bvalue 180 | pnmtopng > XYZ.png > I might be able to hack something for the png export, but for the other > formats > I'm not really sure how to convert them. You may be able to hack something equivalent to my pipe for the png export. In my opinion (and I'm somewhat of a developer myself), it'd smell like a kludgy hack. There should be a cleaner way. But then, I don't know anything about cairo.
