Generate ramp data into a LUT buffer.

Syntax

void MgenLutRamp(
    AIL_ID     LutBufId,    //out
    AIL_INT    StartIndex,  //in
    AIL_DOUBLE StartValue,  //in
    AIL_INT    EndIndex,    //in
    AIL_DOUBLE EndValue     //in
)

Description

This function generates a ramp, inverse ramp, or a constant in the specified LUT buffer region (StartIndex to EndIndex). The increment between LUT entries is the difference between StartValue and EndValue, divided by (the number of entries - 1).

If you need to generate a more complex LUT, use MgenLutFunction or generate the values with your Host system and load them into an Aurora Imaging Library LUT buffer, using MbufPut1d or MbufPutColor.

Parameters

LutBufId (out, AIL_ID)

Specifies the identifier of the LUT in which to generate values. This parameter must be given a valid LUT buffer identifier. Allocate a LUT buffer, using MbufAlloc1d or MbufAllocColor.

StartIndex (in, AIL_INT)

Specifies the first LUT index for which to generate a value.

StartValue (in, AIL_DOUBLE)

Specifies the starting value from which the increment is calculated; that is, the first LUT entry.

EndIndex (in, AIL_INT)

Specifies the last LUT index for which to generate a value.

EndValue (in, AIL_DOUBLE)

Specifies the ending value from which the increment is calculated; that is, the last LUT entry. If both StartValue and EndValue are the same, the entire LUT range is filled with this value. If EndValue is smaller than StartValue, an inverse ramp is generated. This parameter accepts only an integer value, except when using a floating-point LUT buffer.
