Problem with OBJ_BITMAP_LABEL not showing the content properly

[Joe]

Hi all,

i am new to mql4 programming and i would really appriciate your help. I am trying to place a custom picture on the chart. I looked all over for working solution but i can not find it. I followed the example on MQL4 documentation but i can not figure out what i am doing wrong. Could someone with more experience please take a look and let me know what i am doing wrong ?

The entire EA code:

#property copyright "Copyright 2014, MetaQuotes Software Corp."

#property version   "1.00"
#property strict
//+------------------------------------------------------------------+

int OnInit()
  {
   Alert ("random stuff test ON");

   ObjectCreate(0,"BmpLabel",OBJ_BITMAP_LABEL,0,0,0);   
   ObjectSetString(0,"BmpLabel",OBJPROP_BMPFILE,0,"\\Images\\123.bmp");
   ObjectSetInteger(0,"BmpLabel",OBJPROP_XDISTANCE,200);   //x
   ObjectSetInteger(0,"BmpLabel",OBJPROP_YDISTANCE,200);   //y
   ObjectSetInteger(0,"BmpLabel",OBJPROP_XSIZE,30); // width
   ObjectSetInteger(0,"BmpLabel",OBJPROP_YSIZE,30); // height
   ObjectSetInteger(0,"BmpLabel",OBJPROP_HIDDEN,false);
   
   
   return(0);
  }

int deinit()
  {
   Alert ("random stuff test OFF");

   return(0);
  }

The picture is in the MQL4/Images folder. It is in bmp file format and it has 30x30 pixels dimensions.

The code above just creates empty bitmap lable object but no picture is visible..

Thank you so much for the help.

Your bitmap is using compression, which is not managed by OBJ_BITMAP_LABEL. Save it without compression (I opened it with Paint and save it without change, and after that it displayed).

Thank you so much. Yes it works now. This would have never crossed my mind.

Use https://www.xnview.com/en/

MQL expects an older bmp format in order to work.
