ImageGear .NET v25.1 - Updated
Shear Method




ImageGear.Processing.Advanced Assembly > ImageGear.Processing Namespace > ImGearEffects Class : Shear Method
Image to apply shear effect to.
The array of offsets to move the image by. Every offset is in the range -1 to 1. Negative values shift the raster/column to the left, while positive values shift it to the right. The number of offsets is equal to the image width or height depending on the direction of movement (horizontal or vertical).
Specifies how the empty image area is filled.
If true, interpolation is used to smooth shifted pixel values.
If true, the direction of motion is vertical. Otherwise, the direction is horizontal.
Background color to use for filling empty image area. Only used if the specified fill style uses a fill color.
Applies a shearing effect to an image, moving the image rasters or columns according to the specified offsets.

Parameters

page
Image to apply shear effect to.
curvePoints
The array of offsets to move the image by. Every offset is in the range -1 to 1. Negative values shift the raster/column to the left, while positive values shift it to the right. The number of offsets is equal to the image width or height depending on the direction of movement (horizontal or vertical).
fillStyle
Specifies how the empty image area is filled.
interpolate
If true, interpolation is used to smooth shifted pixel values.
vertical
If true, the direction of motion is vertical. Otherwise, the direction is horizontal.
color
Background color to use for filling empty image area. Only used if the specified fill style uses a fill color.
