PNG image displayed larger in wx widget without any scale change

Hi all,

I have a problem figuring out why PNG image is displayed larger in a wx 
widget than its actual size without making any scale change(Python 3.10, 
wxpython 4.2.0, Windows 10). I have tried wx.ScrolledWindow/wx.Panel with 
wxStaticBitmap, wx.lib.statbmp.GenStaticBitmap and overwrite of 
wx.lib.statbmp.GenStaticBitmap's OnPaint method and debugged height, width 
and scale members on every object up to wx.DC and I have not found any 
explanation: height and width are actual height and width  the image and 
scale is 1.0. I have attached picture where in left size is image with its 
real size and in right side is how it is displayed in wx.ScrolledWindow.
I would need first to understand why PNG image is displayed larger in a wx 
widget than its actual size and second to display PNG image in 
wx.ScrolledWindow at its actual real size.

Regards and thank you in advance,
Alexandra
