Description

cvLine(img0, /* the dest image /
cvPoint(10, 10), / start point /
cvPoint(60, 60), / end point /
cvScalar(0, 255, 0, 0), / the color; green /
4, 8, 0); / thickness, line type, shift */

it works if i change the thickness into 1. but with every other value the program compiles but when i run it crushes. is this a bug? how can i draw k thicker line?

Those code is work fine in my environment without crushing.

My environment is
OpenCV Ver: trunk, rev7054, self build
Compiler: Visual Studio 2010
bits and compiler: x86 debug, x86 release, x64 debug and x64 release.

Do you have any error message?

#include <opencv2/opencv.hpp>

int main(int argc, char* argv[])
{
  cv::Mat img0(128, 128, CV_8UC3);

  cvLine(&(img0.operator [[IplImage]]()), /* the dest image */
  cvPoint(10, 10), /* start point */
  cvPoint(60, 60), /* end point */
  cvScalar(0, 255, 0, 0), /* the color; green */
  4, 8, 0); /* thickness, line type, shift */

  cv::imshow("TEST", img0);
  cv::waitKey();
}
