Description

The function opens the bitmap editor and creates a bitmap. The bitmap is saved in PROJ_PATH+"pictures/bitmapeditortest.bmp"

Example

main()
{
  // bitmap in IPictureDisp
  idispatch ipicture;
  /* the colors that are available in the bitmap editor (see also
  bitmapEditor() )
  */
  dyn_string colors = makeDynString("red", "green", "blue");
  // Default Bitmap size
  dyn_int size = makeDynInt(100, 100);
  // Rückgabewert
  int retVal;
  string filename;
  // Open the file selector
  fileSelector(filename, PROJ_PATH+"pictures"); /* writes the path
  PROJ_PATH+"pictures" into the variable filename */
  if (filename != "")
  {
    /*Loads a picture from the PROJ_PATH+"pictures directory into
    the variable 'ipicture'. If an image does not exist, an image is
    created via the bitmap editor */
    ipicture = OLEPicture(filename);
  }
  else
  {
    //A new image (100x100 Pixels)is created via the bitmap
    editor
  }
  while (true)
  {
    /* open the bitmap editor and create the image. The image is
    saved in the variable ipicture */
    if (bitmapEditor(ipicture, colors, size, retVal) != 0)
    {
      // missing or wrong parameters
      return;
    }
    if (retVal < 1 || retVal > 4)
    {
      // PVSSBitmapEditor.dll was not found
      return;
    }
    else if (retVal == 1) // OK, image changed
    {
      string filename = PROJ_PATH+"pictures/bitmapeditortest.bmp";
      //save the bitmap underbitmapeditortest.bmp
      OLEPictureSave(ipicture, filename);
      // ready
      break;
    }
    else if (retVal == 2) //check if the image was changed
    {
      dyn_float df;
      dyn_string ds;
      string ret;
      ChildPanelOnCentralModalReturn("vision/MessageInfo3", "",
      makeDynString("$1:Save the changes?", "$2:Yes", "$3:No",
      "$4:Cancel"), df, ds);
      ret = ds[1];
      if (ret == "true")
      {
        string filename;
        fileSelector(filename, PROJ_PATH+"pictures");

        {
          OLEPictureSave(ipicture, filename);
          break;
        }
      }
      else if (ret = "false")
      {
        break;
      }
      else //if (ret == "Cancel")
      {
        //continue;
      } 
    }
    else if (retVal == 3) // ok, image unchanged
    {
      break;
    }
    else if (retVal == 4) // cancel, image unchanged
    {
