Transparency in Chart Objects

New comment
 

Dear Fellow

I am looking to add transparency to chart objects such as rectangle / triangles as achieved as shown in the Example.png for Butterfly pattern.

I have come across https://www.mql5.com/en/articles/1341 and https://www.mql5.com/en/articles/4575 articles but not sure if they will be help me to achieve transparency? or if any other article to help on this?

Regards

Do you need more than awkward graphics of moving averages? Do you want to draw something more beautiful than a simple filled rectangle in your terminal? Attractive graphics can be drawn in the terminal. This can be implemented through the CСanvas class, which is used for creating custom graphics. With this class you can implement transparency, blend colors and produce the illusion of transparency by means of overlapping and blending colors.
