LOGPEN info  Overview  Group

The LOGPEN structure defines the style, width, and color of a pen. The CreatePenIndirect function uses the LOGPEN structure.

typedef struct tagLOGPEN { // lgpn 

    UINT     lopnStyle; 

    POINT    lopnWidth; 

    COLORREF lopnColor; 




Specifies the pen style, which can be one of the following values:




Pen is solid.


Pen is dashed.


Pen is dotted.


Pen has alternating dashes and dots.


Pen has dashes and double dots.


Pen is invisible.


Pen is solid. When this pen is used in any graphics device interface (GDI) drawing function that takes a bounding rectangle, the dimensions of the figure are shrunk so that it fits entirely in the bounding rectangle, taking into account the width of the pen. This applies only to geometric pens.

Specifies the POINT structure that contains the pen width, in logical units. If the pointer member is NULL, the pen is one pixel wide on raster devices. The y member in the POINT structure for lopnWidth is not used.
Specifies the pen color.


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 GDI objects except polygons and polylines. If the pen color does not match an available red, green, blue (RGB) value, the pen is drawn with a logical (dithered) color. If the pen width is less than or equal to 1, the PS_INSIDEFRAME style is identical to the PS_SOLID style.
