* (
* . . . contents . . . *
* )
* With:
* SFlags Symbolic or numeric flags, for the element as a whole.
* NFlags Numeric flags, for the element as a whole.
* Desc The description of the element. This is one of the three strings which can be
* displayed on the screen.
* Name The name of the element, usually the reference designator.
* Value The value of the element.
* MX MY The location of the element<6E>s mark. This is the reference point for placing the element and its pins and pads.
* TX TY The upper left corner of the text (one of the three strings).
* TDir The relative direction of the text. 0 means left to right for an unrotated element, 1 means up, 2 left, 3 down.
* TScale Size of the text, as a percentage of the <20>default<6C> size of of the font (the default font is about 40 mils high). Default is 100 (40 mils).
* TSFlags Symbolic or numeric flags, for the text.
* TNFlags Numeric flags, for the text.
*
* Elements may contain pins, pads, element
*
* ElementLine [X1 Y1 X2 Y2 Thickness]
* ElementLine (X1 Y1 X2 Y2 Thickness)
*
* ElementArc [X Y Width Height StartAngle DeltaAngle Thickness]
* ElementArc (X Y Width Height StartAngle DeltaAngle Thickness)
* (rotation in clockwise)
* ( Note: Pad is a SMD Pad in Pcbnew, and Pin is a through hole Pad in Pcbnew )
* Pad [rX1 rY1 rX2 rY2 Thickness Clearance Mask "Name" "Number" SFlags]
* Pad (rX1 rY1 rX2 rY2 Thickness Clearance Mask "Name" "Number" NFlags)
* Pad (aX1 aY1 aX2 aY2 Thickness "Name" "Number" NFlags)

* Pin [rX rY Thickness Clearance Mask Drill "Name" "Number" SFlags]
* Pin (rX rY Thickness Clearance Mask Drill "Name" "Number" NFlags)
* Pin (aX aY Thickness Drill "Name" "Number" NFlags)
* Pin (aX aY Thickness Drill "Name" NFlags)
* Pin (aX aY Thickness "Name" NFlags)
*
* Object Flags :
*
* Note that object flags can be given numerically (like 0x0147) or symbolically (like
* "found,showname,square". Some numeric values are reused for different object types.
* The table below lists the numeric value followed by the symbolic name.
* 0x0001 pin
* If set, this object is a pin. This flag is for internal use only.
* 0x0002 via
* Likewise, for vias.
* 0x0004 found
* If set, this object has been found by FindConnection().
* 0x0008 hole
* For pins and vias, this flag means that the pin or via is a hole without a copper
* annulus.
* 0x0010 rat
* If set for a line, indicates that this line is a rat line instead of a copper trace.
* 0x0010 pininpoly
* For pins and pads, this flag is used internally to indicate that the pin or pad
* overlaps a polygon on some layer.
* 0x0010 clearpoly
* For polygons, this flag means that pins and vias will normally clear these polygons
* (thus, thermals are required for electrical connection). When clear, polygons
* will solidly connect to pins and vias.
* 0x0010 hidename
* For elements, when set the name of the element is hidden.
* 0x0020 showname
* For elements, when set the names of pins are shown.
* 0x0020 clearline
* For lines and arcs, the line/arc will clear polygons instead of connecting to
* them.
* 0x0020 fullpoly
* For polygons, the full polygon is drawn (i.e. all parts instead of only the biggest
* one).
* 0x0040 selected
* Set when the object is selected.
* 0x0080 onsolder
* For elements and pads, indicates that they are on the solder side
* 0x0080 auto
* For lines and vias, indicates that these were created by the autorouter.
* 0x0100 square
* For pins and pads, indicates a square (vs round) pin/pad.
* 0x0200 rubberend
* For lines, used internally for rubber band moves.
* 0x0200 warn
* For pins, vias, and pads, set to indicate a warning.
* 0x0400 usetherm
* Obsolete, indicates that pins/vias should be drawn with thermal fingers.
* 0x0400 Obsolete, old files used this to indicate lines drawn on silk.
* 0x0800 octagon
* Draw pins and vias as octagons.
* 0x1000 drc
* Set for objects that fail DRC.
* 0x2000 lock
* Set for locked objects.
* 0x4000 edge2
* For pads, indicates that the second point is closer to the edge. For pins, indicates
* that the pin is closer to a horizontal edge and thus pinout text should be vertical.
* 0x8000 marker
* Marker used internally to avoid revisiting an object.
* 0x10000 nopaste
* For pads, set to prevent a solderpaste stencil opening for the pad. Primarily
* used for pads used as fiducials.
