Computes a CRC Checksum on an image and allows you to specify number of bits of floats/doubles to drop so that the CRC will be same even of this are changed.

        double_bits : int -> int

Parameters

img: Type: GeoEngine.Core.GXNetCIMG
Input image
pul_crc: Type: SystemInt32
Starting CRC (use <define>CRC_INIT_VALUE</define> if none)
float_bits: Type: SystemInt32
<define>IMU_FLOAT_CRC_BITS</define>
double_bits: Type: SystemInt32
<define>IMU_DOUBLE_CRC_BITS</define>

Return Value

Type: Int32
CRC value

Remarks

Very useful for testing where the last bits of accuracy are not as important.
