  206 dst.global_alpha = 0xFF;
  207 dst.rd_mode = 0;
  208
  209 //color conversion
  210 int ret = imcvtcolor(src, dst, src.format, dst.format);
  211 if (ret != IM_STATUS_SUCCESS) {
  212 printf("RGA imcvtcolor failed: %d\n", ret);
  213 }
  
  
  why this code is not working?
  what i'm missing?
  Can anyone please help with this issue.
