ImageResize[image, width]

ImageResize[image, {width, height}]

The Resampling option can be used to specify how to resample the image. Options are:

• Automatic
  
• Bicubic
  
• Bilinear
  
• Box
  
• Hamming
  
• Lanczos
  
• Nearest
  

See Pillow Filters for a description of these.

• • alice = Import["ExampleData/MadTeaParty.gif"]

• • shape = ImageDimensions[alice]

• • ImageResize[alice, shape / 2]

The default sampling method is “Bicubic” which has pretty good upscaling and downscaling quality. However “Box” is the fastest:

• • ImageResize[alice, shape / 2, Resampling -> "Box"]
