Hi all, I've been using Kicad for a while in a 'mucking around' sense, supporting the capture and layout done by contractors of ours.
I have noticed that gerbv is failing to correctly represent gerbers that they have sent for inspection. The gerbers were created by Protel DXP. What appears to be happening is that a single gerber layer contains multiple elements which should be 'xor'ed drawn to create image, however gerbv is 'or'ing the elements together to produce a solid block of colour. I have upload a screen shot to my files showing the issue: http://f1.grp.yahoofs.com/v1/kOaMR_6BSh9DwyfY_QBJla5pSuWqFYKfCbYgbtH-jYzGOCIXLeWs5oktFQtDZbdihOZUVw6cOsKqr9BZ2v7nJuYHKT0a_Jq3/Mungewell/gerbv_failure.PNG The hidden elements of the gerber are visible as the gerbv layer is zoomed in/out, suggesting that they are drawn and then overdrawn/masked by other elements in the layer. On the left in the screenshot is another 'free' (beer) viewer which correctly renders the same layer. It has a mode setting 'colours merged' which will result in the same 'solid block' output as gerbv, normal setting is 'colours solid'. Any suggestions welcome, if not can someone add this as a low priority bug for gerbv. Cheers, Mungewell.
