I patched this program to remove the crashes, and sent the patches
upstream. I think we can assume upstream has stopped?
The program makes a number of errors in calculations, that result in it
attempting to access memory it shouldn't.
Here is a corrected version of the "mirror" function from filter.c
I will try and dig out the fuller patch I made to filter.c for the
laplace transform.
Simon
void mirror (unsigned char *image, int x, int y, int z)
{
int i, j, k;
unsigned char tmp;
for (i = 0; i < y; i++) {
for (j = 0; j < x/2; j++) {
for (k = 0; k < z; k++) {
/*ow, my brain! */
tmp = image[(i * x * z) + (j * z) + k];
image[(i * x * z) + (j * z) + k] =
image[(i * x * z) - (j * z) + k];
image[(i * x * z) - (j * z) + k] = tmp;
}
}
}
}
