Functions

computeBorder

open override fun computeBorder(texWidth: Int, texHeight: Int): MarginInt

The number of pixels the passed texture should be bigger at each direction: left, right, top, left.

expandedBorderRectangle

fun Filter.expandedBorderRectangle(inp: Rectangle): Rectangle

getBorder

fun Filter.getBorder(texWidth: Int, texHeight: Int): MarginInt

render

open override fun render(ctx: RenderContext, matrix: Matrix, texture: Texture, texWidth: Int, texHeight: Int, renderColorMul: RGBA, blendMode: BlendMode, filterScale: Double)

The method in charge of rendering the texture transformed using ctx and matrix. The method receives a texture that should be the original image with computeBorder additional pixels on each side.

renderToTextureWithBorder

fun Filter.~~renderToTextureWithBorder~~(ctx: RenderContext, matrix: Matrix, texture: Texture, texWidth: Int, texHeight: Int, filterScale: Double, block: (Texture, matrix: Matrix) -> Unit)

renderToTextureWithBorderUnsafe

fun Filter.renderToTextureWithBorderUnsafe(ctx: RenderContext, matrix: Matrix, texture: Texture, texWidth: Int, texHeight: Int, filterScale: Double, result: RenderToTextureResult = RenderToTextureResult()): RenderToTextureResult
