L_VecApplyTransformation

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecApplyTransformation( pVector)

/* pointer to a vector handle */

Applies the current transformation to the vector image. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
pVector	Pointer to a vector handle referencing an image drawing.

Returns

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

Comments

This function will apply the current transformation (Rotation, scaling and translation) to the vector image. The vector image objects will be changed.

After a call to this function, rotation, scaling and translation values will be reset.

Example

This example loads a vector drawing, applies some transformation then saves it back.

L_INT VecApplyTransformationExample(L_TCHAR* pszFile)
{
   L_INT nRet;
   VECTORHANDLE TmpVector;     /* Vector handle for initial loading */
   VECTORPOINT point;

   /* Load the drawing */
   nRet = L_VecLoadFile( pszFile, &TmpVector, NULL, NULL );
   if(nRet != SUCCESS)
      return nRet;

   /* Rotate 30 degrees along the 3 axes */
   point.x = 30.0;
   point.y = 30.0;

   nRet = L_VecSetRotation( &TmpVector, &point, NULL, NULL, 0L );

   /* Scale to 200% */
   point.x = 2.0;

   point.z = 2.0;
   nRet = L_VecSetScale( &TmpVector, &point, NULL, NULL, 0L );

   /* Apply the transformation to the image */
   nRet = L_VecApplyTransformation( &TmpVector );

   /* Saves it back */
