Parameters

userDataPtr

The user-defined data set in the caller function.

nends

The number of contours of the polygon.

pends

Pointer to a long array indexed from 0 to nends, including the indexes of the last vertices of each contour.

ncoos

The number of vertices of the polygon.

pcoos

Pointer to a double array including the projected coordinates of the vertices of the polygon, pcoos [2 * i]: the X coordinate of the i-th vertex, pcoos [2 * i + 1]: the Y coordinate fo the i-th vertex.

fpenind

The pen index of the polygon pattern foreground.

forecolor

The GS_RGBColor of the polygon pattern foreground

bpenind

The pen index of the polygon pattern background.

backcolor

The GS_RGBColor of the polygon pattern background.

fillind

The fill index of the polygon pattern

GSPattern

Fill Pattern

longvals, shortvals

Pointer to a long array with three values (longvals) and pointer to a short array with four values (shortvals) which were defined with the seven parameters of the VOCA statement in GDDL scripts. This additional information is stored in the body record of the 3d data structure

shadowElem

Shadow Element.

addInfo

Additional Information

Return Values

If the function succeeds, the return value is NoError. If the function fails, the return value is the error code.
