What is the second piece of code? what is supposed to do?

its a structure that is used in the first piece of code . without it you will get errors

I tried Nikolai's code in MT5. It is constantly resizing the bitmap, I tried to turn that code to a function in which we give new size and it just shows the bitmap with new size, but does not work, when I call CImage Image(bmp,100,100,1); It does not show any thing in the chart, This is my code.
Maybe I should try to work with your own code.

I tried your code, again it seems to be working very well, well done  Lorentzos.

in this case, the code for MT4 and MT5 is the same.

try this mql4 version

@Fatemeh Ameri Use these , they are faster and they don't just shrink the image.

Thank you very much for all your help.

Thanks very much Nikolai Semko, The file works very well, I was wondering what is the issue with MQL5 code, It shows the bitmap on the chart while it is constantly resizing, but when I want to only put it on the chart with a new size and be stable, It does not show any thing. The single line of "CImage Image(bmp,0,0,Transp);" must show the bitmap on the chart, but it does not. what is the error you think?

Permanent resizing was implemented to demonstrate performance.

It's impossible to understand the problem without seeing the code.


PS   Perhaps you have used the function Finish() (I have unsuccessfully named this function, it would be more correct to call it Destroy()), not only in OnDeinit().

The code is very simple, I used your Cimage library, I took it from your MT5 version of ScalingBmp. Like the MT4 version here I expected that it shows the bitmap on the chart with new image size, but it does not show anything. (I attached your MT5 version for reference)
