was the compile error you got originally? That's not a valid cast to
be making.
There's a version of fromImage that just takes the
sensor_msgs/Image -- are you sure that srv.response.left_image is a
sensor_msgs/Image?

Hi
all,
I'm trying to convert sensor_msgs/Image to the opencv image. The
sensor_msgs/Image is defined in the ros service as follows.
<temp_srv.srv>
bool isColor
----
sensor_msgs/Image left_image
The problem has happened at the following code.
IplImage* left_image = bridge_.imgMsgToCv((const
sensor_msgs::ImageConstPtr&) srv.response.left_image,
"passthrough");
Without the casting,(const sensor_msgs::ImageConstPtr&), there was
an
compile error. With the casting, there is a runtime error, segmentation
fault. Is there anyone to know how to get the
sensor_msgs::ImageConstPtr& of the sensor_msgs/Image which is
defined in
the ros service?
I confirmed that there are the proper value of each pixel in the
srv.response.left_image.data[] as well as srv.response.left_image.width
and srv.response.left_image.hight.
Thank you for any comments.
Best,
Soonhac
