Parameters:This function takes one $paramter method that matches one of INTERPOLATE constants . We can also pass the constant directly as
setImageInterpolateMethod (Imagick::INTERPOLATE_BICUBIC);,The list of Interpolating constants is given below:
  • imagick::INTERPOLATE_UNDEFINED (0)
  • imagick::INTERPOLATE_AVERAGE (1)
  • imagick::INTERPOLATE_BICUBIC (2)
  • imagick::INTERPOLATE_BILINEAR (3)
  • imagick::INTERPOLATE_FILTER (4)
  • imagick::INTERPOLATE_INTEGER (5)
  • imagick::INTERPOLATE_MESH (6)
  • imagick: : INTERPOLATE_NEARESTNEIGHBOR (7)
  • imagick::INTERPOLATE_SPLINE (8)
Returned value:This function returns TRUE on success. The programs below illustrate the Imagick::setImageInterpolateMethod() functionin PHP:Program 1:

 
// Create a new imagick object $imagick = new Imagick ( https://media .engineerforengineer.org / wp-content / uploads / engineerforengineer-13.png );  
// Set the interpolation method $imagick -> setImageInterpolateMethod (imagick::INTERPOLATE_BILINEAR);  
// Get the interpolation method $interpolateScheme = $imagick -> getImageInterpolateMethod(); echo $interpolateScheme ; ?>
Output:
3 // Which corresponds to imagick::INTERPOLATE_BILINEAR.
Program 2:  
// Create a new imagick object $imagick = new Imagick ( https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-13.png );  
// Set the interpolation method $imagick -> setImageInterpolateMethod (imagick::INTERPOLATE_NEARESTNEIGHBOR);  
// Get the interpolation method $interpolateScheme = $imagick -> getImageInterpolateMethod(); echo $interpolateScheme ; ?>
Output:
7 // Which corresponds to imagick::INTERPOLATE_NEARESTNEIGHBOR.
