PNG image on the MT4 Chart is not working!

[Anass Habrah]

Hello,

I'm tryng to show png image on the chart when i do run the EA, below the related script:

int init() {
    ShowImage("image.png", 0, 0);

    return INIT_SUCCEEDED;
}

void OnDeinit(const int reason)
  {
   ObjectDelete("ChartImage");
  }
  
void ShowImage(string imageName, int xOffset, int yOffset)
  {
   string objectName = "ChartImage";
   
   ObjectDelete(objectName);
   
   if(!ObjectCreate(0, objectName, OBJ_BITMAP_LABEL, 0, 0, 0))
     {
      Print("Failed to create the object: ", objectName);
      return;
     }
   
   // Set the image properties
   ObjectSetInteger(0, objectName, OBJPROP_XSIZE, 500);
   ObjectSetInteger(0, objectName, OBJPROP_YSIZE, 500);
   ObjectSetString(0, objectName, OBJPROP_TEXT, imageName);
   ObjectSetInteger(0, objectName, OBJPROP_CORNER, CORNER_LEFT_UPPER);
   ObjectSetInteger(0, objectName, OBJPROP_XDISTANCE, xOffset);
   ObjectSetInteger(0, objectName, OBJPROP_YDISTANCE, yOffset);
  }

as you see in the attached screenshot, it is showing the object in the objects list, but not showing it in the chart actually.

please advise where is the wrong ?

You should study the documentation. Just a glance and I realized there is a property called: OBJPROP_BMPFILE.

You can Also check this topic.

If you want to include png file in ex4, then unfortunately in Mql4 there is no such possibility as in mql5:

#resource "//Images//image.png" as uchar image[]

but there is a possibility:
