LVectorBase::ConvertPointToUnit

Summary

Converts the values from point units to other unit types. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Syntax

virtual L_INT LVectorBase::ConvertPointToUnit(pptDst, pptSrc, UnitToUse)

Parameters

pVECTORPOINT pptDst

Pointer to VECTORPOINT structure to be updated with the converted values.

const pVECTORPOINT pptSrc

Pointer to VECTORPOINT structure that contains the source values to be converted.

pVECTORUNIT UnitToUse

Pointer to the VECTORUNIT structure that contains unit types to which the values are converted.

Returns

Comments

To convert values from point units to other unit types, call the LVectorBase::ConvertPointFromUnit function.

To change or retrieve the currently used unit type in the vector toolkit, call the LVectorBase::SetUnit or LVectorBase::GetUnit function.

Example

This example converts values from points unit to Inches unit.

L_INT LVectorBase__ConvertPointToUnitExample(LVectorBase *pVector, pVECTORPOINT pPoint) 
{ 
   VECTORPOINT ConvetedPoint; 
   VECTORUNIT  VecUnit; 
   L_INT nRet = 0 ; 
 
   VecUnit.nSize = sizeof(VecUnit); 
   VecUnit.Unit = VECTOR_UNIT_INCHES; 
 
   nRet = pVector->ConvertPointToUnit( pPoint, &ConvetedPoint, &VecUnit); 
   if(nRet == SUCCESS) 
      nRet = pVector->SetUnit( &VecUnit); 
 
   return nRet ;
