PNG Export not exporting expected layers

[Girvin Herr]

PCB version 4.1.3 and older. First experienced in 2015.
Refer to gEDA user's forum thread with subject "PCB 4.1.3 png export acting weird" dated 1/29/19.

With unwanted layers turned off, leaving only "top silk", "outline", and "pins/pads". Exporting to PNG file with "Only-visible" and "Monochrome" options checked, the resulting file contains the unexpected "Component" and "Solder" layers (traces) as well as the three wanted layers. When choosing "screen-layer-order" and not changing anything else, the resulting file contains only the "top silk" layer.

This behavior has been reproduced by Chad Parker and DJ Delorie.

Temporary work-around: The "signal2" layer was used to create a box around the circuit board. Then checking "screen-layer-order" in the PNG dialog will produce the expected "top silk", "outline" and "pins/pads" layers in the PNG file. If "screen-layer-order" is left unchecked, the PNG file will contain the unwanted layers.

Hi,

If "Pins/Pads" and "Vias" are set to visible they are not exported either.

Kind regards,

Bert Timmerman.
