Specifies a logical pen. Pens draw lines and borders.

lopnStyle

Pen style. GDI requires that drivers support at least the following pen styles:

Value	Meaning
LS_SOLID (0)	Draws solid lines.
LS_DASHED (1)	Draws dashed lines.
LS_DOTTED (2)	Draws dotted lines.
LS_DOTDASHED (3)	Draws lines with alternating dots and dashes.
LS_DASHDOTDOT (4)	Draws lines with a repeating pattern of a dash followed by two dots.
LS_NOLINE (5)	Nothing is drawn.
LS_INSIDEFRAME (6)	Creates a pen with which a line is drawn inside the frame of ellipses and rectangles. If the width of the pen is greater than 1 and the pen style is PS_INSIDEFRAME, the line is drawn inside the frame of all primitives except polygons and polylines; the pen is drawn with a logical (dithered) color if the pen color does not match an available RGB value. The PS_INSIDEFRAME style is identical to PS_SOLID if the pen width is less than or equal to 1.

lopnWidth

A POINT structure with an x member that contains the pen width in device units. A zero-width pen is drawn with the system's smallest width. Negative-width pens have no width and are NULL pens. The y member is ignored.

lopnColor

Color for the pen. Pen colors are specified as physical colors. For palette-capable devices, the value is a color index if the high byte is 0x0FFH.

lopnStyle2

Alternate pen style. May be one of the following:

Value	Meaning
LS_ENDCAP_FLAT (0x01)	End caps are flat.
LS_ENDCAP_ROUND (0x02)	End caps are round.
LS_ENDCAP_SQUARE (0x04)	End caps are square.
LS_JOIN_BEVEL (0x08)	Joins are beveled.
LS_JOIN_MITER (0x10)	Joins are mitered when they are within the current limit that the application set by the SetMiterLimit function. If it exceeds this limit, the join is beveled.
LS_JOIN_ROUND (0x20)	Joins are round.

lopnhcmXform

Transformation for image color matching.
