BitmapShader

FILTER_MODE_DEFAULT

static val FILTER_MODE_DEFAULT: Int

This FilterMode value will respect the value of the Paint#isFilterBitmap flag while the shader is attached to the Paint.

The exception to this rule is when a Shader is attached as input to a RuntimeShader. In that case this mode will default to FILTER_MODE_NEAREST.

Value: 0

FILTER_MODE_LINEAR

static val FILTER_MODE_LINEAR: Int

This FilterMode value will cause the shader to interpolate the output of the shader from a 2x2 grid of pixels nearest to the sample point (i.e. bilinear interpolation).

This value will override the effect of Paint#isFilterBitmap.

Value: 2

FILTER_MODE_NEAREST

static val FILTER_MODE_NEAREST: Int

This FilterMode value will cause the shader to sample from the nearest pixel to the requested sample point.

This value will override the effect of Paint#isFilterBitmap.

Value: 1

BitmapShader

BitmapShader(
    bitmap: Bitmap, 
    tileX: Shader.TileMode, 
    tileY: Shader.TileMode)

Call this to create a new shader that will draw with a bitmap.

getFilterMode

open fun getFilterMode(): Int

Returns the filter mode used when sampling from this shader

getMaxAnisotropy

open fun getMaxAnisotropy(): Int

Returns the current max anisotropic filtering value configured by setFilterMode(int). If setFilterMode(int) is invoked this returns zero.

setFilterMode

open fun setFilterMode(mode: Int): Unit

Set the filter mode to be used when sampling from this shader. If this is configured then the anisotropic filtering value specified in any previous call to setMaxAnisotropy(int) is ignored.

setMaxAnisotropy

open fun setMaxAnisotropy(maxAnisotropy: Int): Unit

Enables and configures the max anisotropy sampling value. If this value is configured, setFilterMode(int) is ignored. Anisotropic filtering can enhance visual quality by removing aliasing effects of images that are at oblique viewing angles. This value is typically consumed as a power of 2 and anisotropic values of the next power of 2 typically provide twice the quality improvement as the previous value. For example, a sampling value of 4 would provide twice the improvement of a sampling value of 2. It is important to note that higher sampling values reach diminishing returns as the improvements between 8 and 16 can be slight.

setOverrideGainmap

open fun setOverrideGainmap(overrideGainmap: Gainmap?): Unit

Draws the BitmapShader with a copy of the given gainmap instead of the gainmap on the Bitmap the shader was constructed from
