Parameters
- kernelSize
- SKSizeI
The kernel size in pixels, in each dimension (N by M).
- kernel
- Single[]
The image processing kernel, with N * M elements in row order.
- gain
- Single
A scale factor applied to each pixel after convolution.
- bias
- Single
A bias factor added to each pixel after convolution.
- kernelOffset
- SKPointI
An offset applied to each pixel coordinate before convolution.
- tileMode
- SKMatrixConvolutionTileMode
How accesses outside the image are treated.
- convolveAlpha
- Boolean
Whether or not all channels are convolved, or just the RGB channels.
- input
- SKImageFilter
The input filter to use.
- cropRect
- SKImageFilter.CropRect
The rectangle to which the output processing will be limited.
Returns
Returns the new SKImageFilter, or null on error.
