•  Set Resizer to Bicubic A=-1.00 (PS 2.0).
  

 

 

 

 Other resizer algorithms:

• Nearest neighbor : use nearest neighbor image scaling algorithm. This method produces blurred images.
  
• Bilinear : Bilinear is the most simple scaling algorithm. Its requires least computing power. It uses CPU for executing scaling algorithm.
• Bilinear (PS 2.0) :  Uses Bilinear resizer algorithm. Its requires least computing power. It uses GPU pixel shader v2.0 (if available) for executing scaling algorithm.
• Bicubic A=-0.60 (PS 2.0)  :  Uses Bicubic scaling algorithm which produces better image compared to linear resizer. Its requires low computing power. It uses GPU pixel shader v2.0 (if available) for executing scaling algorithm. 
• Bicubic A=-0.75 (PS 2.0)  :  Uses Bicubic scaling algorithm. Its requires low computing power. It uses GPU pixel shader v2.0 (if available) for executing scaling algorithm. With parameter A=-0.75 it produces sharper images compared to A=-0.60.
• Bicubic A=-1.00 (PS 2.0)  :  Uses Bicubic scaling algorithm which produces better image compared to linear resizer. Its requires low computing power. It uses GPU pixel shader v2.0 (if available) for executing scaling algorithm. With parameter A=-1.00 it produces sharper images.
