C++ (Cpp) imImageCopyData Examples

Example #1

File: im_houghline.cpp Project: Vulcanior/IUP

int imProcessHoughLinesDraw(const imImage* src_image, const imImage *hough, const imImage *hough_points, imImage *dst_image)
{
  int theta, line_count = 0;

  if (src_image != dst_image)
    imImageCopyData(src_image, dst_image);

  listnode* maxima = findMaxima(hough_points, &line_count, hough);

  ReplaceColor(dst_image);

  costab = (double*)malloc(180*sizeof(double));
  sintab = (double*)malloc(180*sizeof(double));

  for (theta=0; theta < 180; theta++)
  {
    double th = (M_PI*theta)/180.;
    costab[theta] = cos(th);

  }

  DrawPoints(dst_image, maxima);

  free(costab); costab = NULL;

Example #2

File: im_render.cpp Project: Vulcanior/IUP
