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.

Required DLLs and Libraries

LVKRN

For a listing of the exact DLLs and Libraries needed, based on the toolkit version, refer to Files To Be Included With Your Application.

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; 
}
