L_LVKRN_API L_INT L_VecSetViewMode(pVector, nMode)

pVECTORHANDLE pVector;	/* pointer to a vector handle */
L_INT nMode;	/* the view mode to set */

Sets the view mode.

Parameter	Description
pVector	Pointer to the vector handle.
nMode	The view mode to set. Possible values are:
	Value	Meaning
	VECTOR_VIEWMODE_FIT	Fit the drawing on the view-port, keeping the aspect ratio.
	VECTOR_VIEWMODE_SNAP	Snap the drawing into the view-port.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function will set the view mode used when drawing the vector handle.

The view mode is used with the view port to determine the resulting physical drawing extents.
