What are you doing? Why do you need such a linkage - to price via pixels?
Trying to conquer the world.)
In fact, I want to transfer a couple of products to MT5. They have such a specificity that it won't work without XY.
Try to output/update the canvas not more than 30 times per second
To speed up the tester? Well not much time has passed yet, I will be poking buttons and trying different manipulations.

That's what I'm asking. ?
Nikolai, I have a question about kanvas. I also have one trading panel on MT4.
I'm thinking of rewriting graphics to look nice on MT5 at different screen resolutions. The only problem is that almost all graphics are in bmp.
Is it realistic to monitor the font size and make a "rubber design" of the panel changing the size of bmp files? Or, is it easier to make two bmp graphics - "normal" and 4k?

I haven't experimented with this kind of kanvas yet.
There might be a more ideal solution here.

Of course it is possible. The main advantage of kanvas is 100% flexibility and possibility of everything and no limitations. The main thing is creativity.
You can download my latest free product, open the panel and scale the MT5 window.
Even bmp can be scaled in kanvas. I gave you an example somewhere.
Here it is:

you can use my better (in terms of image) algorithm or the simpler and faster one by Yuri.

Just don't forget about the parameter

Thank you. I think if I'm pressed for time, it's easier to freelance for rewriting graphics through kanvas.
By the way, the optimization is slowly starting to work out. The tester is now faster than it was. The only thing left to do is to find and fix why the histogram does not shift during the operation.
I am also a bit annoyed by MT5 for loading of quotes and the effect it produces in the process. Here's a description and a prototype -https://www.mql5.com/ru/forum/373465
I'm doing a cross-link, because who knows if that topic will be seen or not, and there are strong progers here, and maybe they'll pay attention.Thank you. I think if time is tight, it would be easier to freelance to rewrite the graphics through Canvas.
I doubt it can be done in freelance. If you want to be sure that the entrance to the site is already opened and the entrance to the site is already open, then the entrance is closed.

I'm making a cross-link, since who knows if they will see that thread or not, and there are strong progamers here, and maybe they will pay attention.That's why I don't like objects, because they have their own life in their flows, the control over which is not available to you. With kanvas on the contrary - everything is in your hands. That's why I have to write additional code for the tester with canvas not to slow down when calculating frames at each tick more than 30 times per second.
Also, working with TFs and history loading is very unreasonable and inefficient in MT5. Only M1 are loaded, and in an unpacked form, while others are only calculated from M1. Therefore, if you enable MN1 for the first time, 100 bars will take more than 10 seconds to load. I had to write the bar load myself and convert M1 to packed form and have all calculated TFs in memory. All my TFs together with M1 take up a fraction of the space in RAM than just the regular M1 in MT5.

Why don't the Admins and programmers of the project react? This is the primary basis. I've heard that some traders find it hard to switch to MT5 because of the slowness with switching timeframes.
But I did not understand it until I faced it myself. And now it turns out that programmers write their own loader for convenience.
But I have a rectangle chart written through a canvas that is not flashing but bouncing left/right
