LVectorBase::ApplyTransformation

#include "ltwrappr.h"

virtual L_INT LVectorBase::ApplyTransformation(L_VOID)

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

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

This function will apply 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 opens an image, rotates it, and saves the result as a .dxf file. The vector is saved as transformed.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT LVectorBase__ApplyTransformationExample(HWND hWnd) 
{ 
   L_INT          nRet; 
   LVectorBase    Vector; 
   RECT           rect; 
   //Load the drawing 
   nRet = Vector.Load(MAKE_IMAGE_PATH(TEXT("random.dxf"))); 
   if(nRet != SUCCESS) 
      return nRet; 
   //Attach to window 
   nRet = Vector.AttachToWindow(hWnd); 
   if(nRet != SUCCESS) 
      return nRet; 
   //Set viewport 
   GetClientRect(hWnd, &rect); 
   nRet = Vector.SetViewport(&rect); 
   if(nRet != SUCCESS) 
      return nRet; 
   //Rotate 
   VECTORPOINT rotatePoint; 
   nRet = Vector.GetRotation(&rotatePoint); 
   if(nRet != SUCCESS) 
      return nRet; 
   rotatePoint.x += 30.0F; 
   rotatePoint.y -= 100.0F; 
   rotatePoint.z += 50.0F; 
   Vector.SetRotation(&rotatePoint,NULL,NULL); 
   //Make transformations apply to save 
   nRet = Vector.ApplyTransformation(); 
   if(nRet != SUCCESS) 
      return nRet; 
   //Save 
   Vector.SetFileName(MAKE_IMAGE_PATH(TEXT("image.dxf"))); 
   nRet = Vector.Save(FILE_DXF); 
   if(nRet != SUCCESS) 
      return nRet; 
   return SUCCESS;
