2个错误在行中frameo(&Ovl)(预期为")",预期表达式).

desttemp = dest1;
res1 = contour8(&Area,x0,y0,~2,threshold,length,&desttemp);

最后一个错误位于最后一行(long类型的参数与U32类型的参数不兼容).contour8的函数签名是I32 contour8(image *a, I32 x0, I32 y0, I32 dir, I32 thr, …

我尝试使用以下签名调用函数:

I32 contour8(image *a, I32 x0, I32 y0, I32 dir, I32 thr, U32 lng, U32 **dst);

使用此代码:

int posx = 100, posy = 100, dx = 300, dy = 300;
long length = 5000;
int threshold = 125;
int lx, x0 = 0, y0 = 0;
int res1 = 0, res2 = 0, *rlc, *input, i;
long dest1, dest2, desttemp, addr;
char c;
image Area;

desttemp = dest1;
res1 = contour8(&Area, x0, y0, ~2, threshold, length, &desttemp);

但是在编译时我得到以下错误:
