ImageScaleToFit

Creates a resized image with the aspect ratio maintained.

ImageScaleToFit( image, fitWidth, fitHeight [, interpolation [, blurFactor ] ] )

Returns: void

Argument Description Default
image
any, required

The image on which this operation is performed.

Alias: name, source

fitWidth
string, required

The width of the bounding box in pixels. You can specify an integer, or an empty string ("") if the fitHeight is specified.

fitHeight
string, required

The height of the bounding box in pixels. You can specify an integer, or an empty string ("") if the fitWidth is specified.

interpolation
string, optional

The interpolation method for resampling. You can specify a specific interpolation algorithm by name (for example, hamming), by image quality (for example, mediumQuality), or by performance (for example, highestPerformance). Valid values are:

  • highestQuality (default)
  • highQuality
  • mediumQuality
  • highestPerformance
  • highPerformance
  • mediumPerformance
  • nearest
  • bilinear
  • bicubic
  • bessel
  • blackman
  • hamming
  • hanning
  • hermite
  • lanczos
  • mitchell
  • quadratic

highestQuality

blurFactor
number, optional

The blur factor used for resampling. The higher the blur factor, the more blurred the image (also, the longer it takes to resize the image). Valid values are 1-10.

myImg = imageNew("",400,400,"rgb","70a1ff");
imageScaleToFit(myImg,80,"","hamming");
