blur()

static ImageFilter org.skia.jetski.ImageFilter.blur ( float  sigmaX, float  sigmaY, TileMode  tileMode, float  left, float  top, float  right, float  bottom, @Nullable ImageFilter  input  )

inlinestatic

Create a filter that calculates the diffuse illumination from a distant light source, interpreting the alpha channel of the input as the height profile of the surface (to approximate normal vectors).

Parameters

sigmaX	The Gaussian sigma value for blurring along the X axis.
sigmaY	The Gaussian sigma value for blurring along the Y axis.
tileMode	The tile mode applied at edges
left	Left, top, right, bottom are used to make the crop rect
input	The input filter that is blurred, uses source bitmap if this is null.

                                                                {

            nativeInput = input.getNativeInstance();

        return new ImageFilter(nBlur(sigmaX, sigmaY, tileMode.nativeInt,
                                     left, top, right, bottom, nativeInput));
    }

distantLitDiffuse()

static ImageFilter org.skia.jetski.ImageFilter.distantLitDiffuse ( float  x, float  y, float  z, Color  c, float  surfaceScale, float  kd, @Nullable ImageFilter  input  )

inlinestatic

Create a filter that calculates the diffuse illumination from a distant light source, interpreting the alpha channel of the input as the height profile of the surface (to approximate normal vectors).

Parameters

x,y,z	The direction to the distance light.
c	The color of the diffuse light source.
surfaceScale	Scale factor to transform from alpha values to physical height.
kd	Diffuse reflectance coefficient.
input	The input filter that defines surface normals (as alpha), or uses the source bitmap when null.

dropShadow()

static ImageFilter org.skia.jetski.ImageFilter.dropShadow ( float  dx, float  dy, float  sigmaX, float  sigmaY, Color  c, @Nullable ImageFilter  input  )

inlinestatic

Create a filter that draws a drop shadow under the input content. This filter produces an image that includes the inputs' content.

Parameters

dx	The X offset of the shadow.
dy	The Y offset of the shadow.
sigmaX	The blur radius for the shadow, along the X axis.
sigmaY	The blur radius for the shadow, along the Y axis.
c	The color of the drop shadow.
input	The input filter, or will use the source bitmap if this is null.
