IG_vect_ent_rotate

In This Topic

This function rotates the entity on the specified angle about the specified vector.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_vect_ent_rotate( HIG_VECT_ENTITY hEntity, VECT_REAL fAngle, VECT_REAL i, VECT_REAL j, VECT_REAL k, VECT_BOOL bBefore );

Arguments:

Name	Type	Description
hEntity	HIG_VECT_ENTITY	Handle of the entity to be rotated.
fAngle	VECT_REAL	Rotation angle, in radians.
i	VECT_REAL	X coordinate of the rotation vector.
j	VECT_REAL	Y coordinate of the rotation vector.
k	VECT_REAL	Z coordinate of the rotation vector.
bBefore	VECT_BOOL	Specifies how the rotation matrix is multiplied by the entity matrix. TRUE means right multiplication; FALSE means left multiplication.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

This function does not process image pixels.

Sample:

Vector

Remarks:

This function creates rotation matrix using angle fAngle, and rotation vector i, j, k and multiplies it by the correct entity matrix according to the bBefore flag.
