passing Jbytearray to unsigned char
Hello Group:
I am newer in JNI and I have a little problem:
I have a native method with the follow signature:
public native int enroll(byte[] template);
now I have it type data in C:
typedef unsigned charFPIMAGE;/* fp image data object */
Implementing my native method i need to call a function of a library to proccess this image(in this case the byte[]) but the signature of this method is:
FPCODE *cA = bd_fpCode(FPIMAGE *A, int xh, int yw, FPCODE *buf, int*qval);
A = pointer to the fingerprint image pixel matrix
xh = number of rows (height)
yw = number of columns (width)
buf = pointer to an external buffer with minimum size of FPC_MAXLEN bytes as destination for the created fingerprint code
qval = fingerprint image quality value (in %)
cA = pointer to fp-code (cA == buf) or NULL, if processing failed
There is my problem i don't now how to pass o convert my byte[] template to a object FPIMAGE.
you can help me please!
