Public methods

create

Added in API level 19
static fun create(
    rs: RenderScript!, 
    e: Element!
): ScriptIntrinsicHistogram!

Deprecated: Deprecated in Java.

Create an intrinsic for calculating the histogram of an uchar or uchar4 image. Supported elements types are Element.U8_4, Element.U8_3, Element.U8_2, Element.U8

Parameters
rs RenderScript!: The RenderScript context
e Element!: Element type for inputs
Return
ScriptIntrinsicHistogram! ScriptIntrinsicHistogram

forEach

Added in API level 19
fun forEach(ain: Allocation!): Unit

Deprecated: Deprecated in Java.

Process an input buffer and place the histogram into the output allocation. The output allocation may be a narrower vector size than the input. In this case the vector size of the output is used to determine how many of the input channels are used in the computation. This is useful if you have an RGBA input buffer but only want the histogram for RGB. 1D and 2D input allocations are supported.

Parameters
ain Allocation!: The input image

forEach

Added in API level 21
Deprecated in API level 31
fun forEach(
    ain: Allocation!, 
    opt: Script.LaunchOptions!
): Unit

Deprecated: Deprecated in Java.

Process an input buffer and place the histogram into the output allocation. The output allocation may be a narrower vector size than the input. In this case the vector size of the output is used to determine how many of the input channels are used in the computation. This is useful if you have an RGBA input buffer but only want the histogram for RGB. 1D and 2D input allocations are supported.

Parameters
ain Allocation!: The input image
opt Script.LaunchOptions!: LaunchOptions for clipping

forEach_Dot

Added in API level 19
fun forEach_Dot(ain: Allocation!): Unit

Deprecated: Deprecated in Java.

Process an input buffer and place the histogram into the output allocation. The dot product of the input channel and the coefficients from 'setDotCoefficients' are used to calculate the output values. 1D and 2D input allocations are supported.

Parameters
ain Allocation!: The input image

forEach_Dot

Added in API level 21
Deprecated in API level 31
fun forEach_Dot(
    ain: Allocation!, 
    opt: Script.LaunchOptions!
): Unit

Deprecated: Deprecated in Java.

Process an input buffer and place the histogram into the output allocation. The dot product of the input channel and the coefficients from 'setDotCoefficients' are used to calculate the output values. 1D and 2D input allocations are supported.

Parameters
ain Allocation!: The input image
opt Script.LaunchOptions!: LaunchOptions for clipping

getFieldID_Input

Added in API level 19
fun getFieldID_Input(): Script.FieldID!

Deprecated: Deprecated in Java.

Get a FieldID for the input field of this intrinsic.

Return
Script.FieldID! Script.FieldID The FieldID object.

getKernelID_Separate

Added in API level 19
fun getKernelID_Separate(): Script.KernelID!

Deprecated: Deprecated in Java.

Get a KernelID for this intrinsic kernel.

Return
Script.KernelID! Script.KernelID The KernelID object.

setDotCoefficients

Added in API level 19
fun setDotCoefficients(
    r: Float, 
    g: Float, 
    b: Float, 
    a: Float
): Unit

Deprecated: Deprecated in Java.

Set the coefficients used for the RGBA to Luminocity calculation. The default is {0.299f, 0.587f, 0.114f, 0.f}. Coefficients must be >= 0 and sum to 1.0 or less.

Parameters
r Float: Red coefficient
g Float: Green coefficient
b Float: Blue coefficient
a Float: Alpha coefficient

setOutput

Added in API level 19
fun setOutput(aout: Allocation!): Unit

Deprecated: Deprecated in Java.

Set the output of the histogram. 32 bit integer types are supported.

Parameters
aout Allocation!: The output allocation
