Shears an image either horizontally or vertically.

`imageShear(name, shear [, direction] [, interpolation]) `

*→ returns void*

`someImage.shear(shear [, direction] [, interpolation])`

Required

The image on which this operation is performed.

Required

Shear value. Coordinates can be integers or real numbers.

Default:

`horizontal`

Shear direction
**Values: **

`horizontal`

`vertical`

Default:

`nearest`

Type of interpolation
**Values: **

`nearest: Applies the nearest neighbor method of interpolation. Image quality is lower than the other interpolation methods, but processing is fastest.`

`bilinear: Applies the bilinear method of interpolation. The quality of the image is less pixelated than the default, but processing is slower.`

`bicubic: Applies the bicubic method of interpolation. Generally, the quality of image is highest with this method and processing is slowest.`

CF 11+ Shear the image by a factor of 1 on a horizontal axis

```
imgObj = imageRead("http://cfdocs.org/apple-touch-icon.png");
imgObj.shear(1);
cfimage(action="writeToBrowser", source=imgObj);
