imageScaleTofit Code Examples and CFML Documentation

Argument Reference

name string
Required

The ColdFusion image on which this operation is performed.

fitWidth numeric
Required

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

fitHeight numeric
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

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).

Values:

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

blurfactor boolean

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).

Values:

1-10

Examples

Sample code invoking the imageScaleTofit function

Tag Syntax

This example shows how to resize an image to fit a 100x100-pixel square while maintaining the aspect ratio.
