使用improcess, 从源buf的指定sx,sy,sw,sh复制一个区域到目标buf指定dx,dy,dw,dh,其中sw=dw,sh=dh,图像显示错位问题？

问题：使用improcess, 从源buf的指定sx,sy,sw,sh复制一个区域到目标buf指定dx,dy,dw,dh,其中sw=dw,sh=dh,图像显示错位，不知是对improcess的理解不正确，还是这是一个BUG，向各位讨教。

librga源码中没有这样使用的例子，是我参考imtranslate源码实现，imtranslate与我代码不同点仅是imtranslate中sx,sy为0。

代码如下：

void drm_2da_cp_rect(uint8_t * dst, uint8_t * src, int bw, int bh, int sx,int sy, int sw, int sh, int dx,int dy) {
int usage = 0;
int ret = 0;
rga_buffer_t pat;

    im_rect srect;
    im_rect drect;
    im_rect prect;

rga_buffer_t     rga_src;
rga_buffer_t     rga_dst;

static im_handle_param_t param;

param.width = bw;
param.height = bh;
param.format = RK_FORMAT_RGBA_8888;

    rga_buffer_handle_t src_handle = importbuffer_virtualaddr(src, &param);
if (src_handle <= 0) {
	printf("Failed to import virtualaddr for src channel!\n");
	return;
}

rga_buffer_handle_t dst_handle = importbuffer_virtualaddr(dst, &param);
if (dst_handle <= 0) {
		printf("Failed to import virtualaddr for dst channel!\n");
	return;
}

rga_src = wrapbuffer_handle(src_handle, bw, bh, RK_FORMAT_RGBA_8888,bw,bh);
rga_dst = wrapbuffer_handle(dst_handle, bw, bh, RK_FORMAT_RGBA_8888,bw,bh);

empty_structure(NULL, NULL, &pat, &srect, &drect, &prect);

    if ((rga_src.width != rga_dst.width) || (rga_src.height != rga_dst.height))
       return;

srect.x = sx;
srect.y = sy;
srect.width = sw;
srect.height = sh;

drect.x = dx;
drect.y = dy;
drect.width = sw;
drect.height = sh;

ret = imcheck(rga_src, rga_dst, srect, drect);
if (ret != IM_STATUS_NOERROR) {
	printf("%d, check error! %s \n", __LINE__, imStrError((IM_STATUS)ret));
} else {
	usage |= IM_SYNC;
	printf("src buff: %d-%d    dst Buff: %d-%d \n", rga_src.wstride,rga_src.hstride,rga_dst.wstride,rga_dst.hstride);
	printf("sx:%d  sy:%d  sw:%d  sh:%d  dx:%d  dy:%d  dw:%d  dh:%d \n",srect.x,srect.y,srect.width,srect.height,drect.x,drect.y,drect.width,drect.height);
	ret = improcess(rga_src, rga_dst, pat, srect, drect, prect, usage);
	if (ret != IM_STATUS_SUCCESS) 
		printf("%d, rga copy error! %s \n", __LINE__, imStrError((IM_STATUS)ret));
}
releasebuffer_handle(src_handle);
    releasebuffer_handle(dst_handle);

}

Sorry, I am only mirroring this code and am not familiar with the internal code or API specs.
However, I will keep this Issue open in the future as there may be others who can advise me.
